what is the relationship between humans animals and plants

Humans are a type of animal but the difference is that we can think in a much more complex way and we've built real and legitamite civilizations. Not here's the . Interrelation of Soils and Plant, Animal, and Human Nutrition .. and the ash of plants grown on different soil types; that there was a direct relationship between. Plants and animals evolved together, so they have complex relationships. The age-old relationships between plants and pollinators is threatened, As more land is cleared for human habitation, bees, butterflies, bats, and.

Students develop food chains based on the relationships they have discovered between the plants and animals. Students make posters about their food chains using pictures as illustrations.

Once the individual food chains are completed, they are studied by the class to see if there are any common organisms and pathways.

Plant/Animal Relationships

The food chains are then combined into a food web. They draw the food web in their Science Journals. Students investigate other ecosystems and habitats that they have not studied or that are not found in New Jersey.

They make diagrams in their Science Journals to illustrate the food chains and make them into food webs. Students investigate the marine environment and the food chains that are present in the ocean. They learn that the ocean will be called upon to provide more and more food in the future, a field known as aquaculture. Students investigate nutrient cycles in the environment. Animals played an important part in all sorts of labor-intensive tasks up until the development of advanced technology.

Horses provided fast transportation before the development of cars.

They could pull trees from the ground, pull plows to till fields and carry building materials long distances, allowing people to build tougher homes and barns in a wider variety of places. Dogs assisted people in hunting.

Certain breeds were developed to hunt in different ways, from terriers that dug up rodents and other small pests from the ground to pointers that helped hunters locate birds or deer in tall brush. In some cases, dogs could even be trained to chase, kill and retrieve animals at a hunter's command, making in unnecessary for humans to risk injury in order to obtain meat. In parts of the world where the latest technology is unavailable, animals are still used to perform tasks that would otherwise be difficult or impossible.

Plants and Animals Used as Tools Animal bone could be carved into knives, spears and other useful instruments. Animal bladders were sometimes used to create bags, while hollowed-out horns from animals like rams could be used to transmit sounds over long distances.

Wood from trees was used to build everything from the bodies of spears to hunting bows. Later on in human history, wood was used in the creation of the first guns. Bird feathers were often used to balance arrows, or to add warmth to clothing, especially moccasins.

Early hunters usually tried to use every part of an animal's body, if possible, to maximize its usefulness. If an animal such as a buffalo was killed, the buffalo's own horns and skull fragments might be used to remove fur from the hide so that the hide could be tanned. Magnesium is closely associated with calcium and phosphorus, both in its distribution and metabolism, and among other things it appears to assist in the normal functioning of nerves.

The lack or unavailability of iodine in soils and crops results in human and animal goiter. Before iodine feeding was practiced in Montana, it is estimated that goiter caused an annual loss of many thousands of pigs. According to Maynard the principal demand for iodine in farm animals occurs during pregnancy.

The Production and Use of Energy The importance of continuing investigations to determine which elements are essential not only for the best development of plants but for the production of the highest quality plants—which, when consumed, will meet the nutritional requirements of man and animals—is evident.

Importance of Plants to humans and animals in everyday's life

Many factors affect the growth of plants and their value as food. Nutrient materials must be either in solution or capable of becoming dissolved at the margin of the root hair before they enter the plant body.

After their entrance they become a part of the vast complex of compounds that make up the plant body, and when the plants are consumed by man or animals, the nutrients included become part of their bodies. It is the capacity of green plants for manufacturing food—for accumulating energy as food—that makes them prominent in any system of economy dealing with living things. Green plants, in the presence of sunlight, accomplish this by combining the carbon dioxide of the air and water to form carbohydrates.

The minerals and other substances absorbed by the plant from the soil, water, or atmosphere are combined with the carbohydrates or other materials formed from them and help make up such compounds as proteins, fats, vitamins, and other growth and regulatory factors. These combinations of foods, both simple and complex, found in plants are the chief source of energy and are essential for the health of man and animals.

The importance therefore of producing plants of the highest nutritional quality can easily be appreciated. In addition the nutritive value of animal products as regards mineral content and, in a large part, vitamins is dependent on the plant foods they consume.

This emphasizes the importance of knowing whether the necessary and desirable nutrients are available in the different soil types of the various regions in the country—to insure not only crop productivity but also that such crops may contain these elements.

As previously mentioned, evidence indicates that this is not so in many instances. In other words, certain minerals are not present or available in sufficient amounts in some soils for the most satisfactory growth and development of many crop plants. It can be assumed, therefore, that the plants produced in such areas might not furnish certain of the important minerals and compounds needed for the best development and health of man and animals.

This fact takes on considerable significance when we realize that large segments of the population in certain areas of this and other countries obtain practically all their food directly from the plants or from animals that eat the plants produced in their own local communities. Although food products are better distributed today than ever before and more variety is available from a much larger area, thus lessening but not eliminating the possibilities of certain deficiencies, there are still great groups of people who are not in a position to purchase much food in addition to that which they produce.

Accordingly, in such groups the diet is limited. Even in cities certain low-income groups have a restricted diet. Such dietary deficiencies no doubt result primarily from too low an intake of certain classes of foods, such as milk, green vegetables, fish, and lean meats.

If such foods are also deficient in certain essential elements, the probability of physiological disturbances and reduced vitality is increased. In the past serious bone, skin, digestive, and nervous disorders, among other maladies, occurred in certain localities. It is now known that many of these troubles resulted from restricted diets or from eating plant and animal products produced on soils either deficient in certain elements or containing elements injurious to health.

Even today there are regions where troubles such as goiter, skin diseases, weak and deformed leg bones, mottled and furrowed teeth, and nervous disorders are all too common. The book by J. I am well aware that dietary deficiencies among large groups of people can be traced to economic causes—the lack of sufficient income to obtain a good diet easily.

But this rather emphasizes than minimizes the responsibility of the agricultural scientist to discover ways of improving limited diets. He may feel rather helpless when it comes to the question of how to increase the purchasing power of large numbers of people, but the other problem—improving the quality of the foods they do get—should be within his grasp.

Analyses of the same kind of plant grown in different regions and showing striking differences in composition are recorded. But even making such allowances, the differences in percentages of some elements are so large as to leave little doubt that they are due to the presence or absence of certain elements in the soil.

It is well known that the chemical composition of plants—with respect to both their mineral and organic content—may be greatly changed by modifying various treatments, such as fertilizer, irrigation, or pruning practices. It is thus possible to change the food value of the plants in either the fresh or the cured condition through methods of treatment and handling of the soil and plants.

In general there is not a direct, simple relation but a complex one between water supply and available nutrients.

Plants and Animals in the Environment

Increasing the amounts of mineral nutrients if water is deficient or increasing the available water if minerals are deficient is ineffective in promoting crop yield. In addition to considering methods of handling the soil as regards the absorption and utilization of minerals, the synthesis of foodstuffs, and the energy accumulation by plants, attention must also be given to the way in which the top of the plant is managed as affecting these processes.

Too often practices applied to the soil have been antagonistic in their effects to those applied to the part of the plant above the soil. Thus the time of pruning or cutting plants in relation to their stage and type of growth, as affecting later composition and response, is important.

The differences in palatability and composition of certain vegetables grown by different methods and at various stages of growth are well known. Protein content decreases and crude fiber increases with maturity. Proper curing and storage keeps leaves from shattering and retains a good green color—the best indicator of high vitamin A content. Thus, by practices such as spraying, pruning, and shading, the horticulturist can influence the capacity of plants to synthesize, translocate, and store carbohydrates.

The agronomist accomplishes the same end by cutting, mowing, pasturage, and other practices. The interrelation of the various cultural and management practices as affecting the composition and growth of plants has been well described by Kraus and Kraybill5 and need not be discussed here.

Suggested Investigations and Objectives Scientists have used water cultures for many years to determine those elements essential for plant growth and will continue to make valuable contributions by this method. The importance, then, of knowing more about the soils of the country—with particular reference to their origin, chemical and physical composition, amenability to various treatments, and effectiveness in producing plants of high quality—seems clear.

The fact that many of the sandy soils of the Coastal Plain, certain calcareous soils, and the muck soils, as well as other types, are deficient in some of the minerals essential for plants, animals, and man has been pointed out. Similarly, the presence of toxic elements such as selenium and fluorine in certain soil areas has been noted.
