Plants, animals, and the environment are not dependent on each other for the use of Carbon and Oxygen.

Animals and humans depend on plants for many things, and without plants, there could be no life on Earth.

Explanation:

1. Plants are the primary producers. They are the only organisms that can make their own food. Animals, who are incapable of making their own food, depend on plants for their supply of food.

2.The oxygen that animals breathe comes from plants. Through photosynthesis, plants take energy from the sun, carbon dioxide from the air, and water and minerals from the soil. They then give off water and oxygen. Animals then use oxygen process called respiration. Respiration is the process used by organisms to release energy from food, and carbon dioxide is given off.

3.Plants also provide habitat for many species of animals. The plants provide food, shelter from weather (rain, sun), nesting place, sleeping ground and hideout from predators.

For example: Different animals live in different parts of the rainforest. Scientists divide the rainforest into zones based on the living environment.
