Question

described interdependence of biotic and abiotic components by taking nitrogen cycle as an example

Answer 1

Not only are all plants, animals and human beings dependent on their environment, but they are also interdependent upon each other in several ways. For example, plants are eaten by animals as food. Through photosynthesis, plants produce oxygen, which is necessary for the survival of all living organisms. Forests are the natural habitats of wild animals, while the woods of trees are used by humans for various purposes like building houses, boats, furniture, etc.

On the other hand, animals help plants reproduce by helping in the pollination of se eds. Nitrogen is essential for the survival of plants, and they are provided with this nitrogen by the bacteria that live in the soil and in the roots of some plants. Photosynthesis, which is the way by which plants make their food, depends upon factors like sunlight, water and carbon dioxide. The carbon dioxide is provided by humans and animals through respiration.
