In this work, we will consider the scheme: what do plants give animals and humans. Without our green counterparts, life on Earth would have been completely impossible. They give us the most necessary - oxygen. Life is impossible without breathing, even fish underwater use the result of plant photosynthesis for breathing .
In addition, many animals use them for food and as a source of water. The scheme we are considering: what plants give to animals and humans will contain all the elements that are used by plants in the process of oxygen reproduction.
It is necessary to mention one more fact: although plants produce oxygen, they nevertheless consume it. The amount of production far exceeds consumption, so we use it also. But we will talk more about this later.
Breath
The scheme presented in this section: what plants give to animals and humans shows the process of gas reproduction, which all living creatures of our planet breathe. This process in biology is called photosynthesis. Let's look at how this happens.
The scheme presented by us: what plants give to animals and humans shows that the process of photosynthesis is actually very complicated. Let's take a look at how it happens:
- the plant takes water from the soil;
- the special substance chlorophyll and sunlight help in the process of photosynthesis;
- the plant receives the necessary energy;
- photosynthesis waste (oxygen) is released into the environment.
From all that has been said, it becomes clear: photosynthesis has two advantages at once: saturation of plants with energy and enrichment of the atmosphere with oxygen.
Food
So, what do plants give animals and humans? The scheme (class 3), the photo of which we provided, shows us: many animals feed on green plants.
Our planet has a large number of herbivores. Moreover, they all eat different parts of green plants. This makes it possible for many species of herbivores to inhabit the same territory without a struggle for food. So, some can pinch grass, and eat leaves from shrubs and trees, some reach even the highest sections of trees. For example, an elephant can both pinch grass with a trunk and reach leaves on trees, and giraffes, thanks to their long necks, can feed on leaves located at the very top. This allows these animals to live in the same territory without competition for food.
