Detailed explanation-1: -A food chain shows how energy is transferred from one living organism to another via food. It is important for us to understand how the food chain works so that we know what are the important living organisms that make up the food chain and how the ecology is balanced.

Detailed explanation-2: -A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees and shrubs, the giraffes (that eat trees and shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link.

Detailed explanation-3: -Interdependency of Plants and Animals Animals breathe oxygen and exhale carbon dioxide. Plants take in carbon dioxide and release oxygen back into the air. 2. Animals need plants for food and shelter.

Detailed explanation-4: -The food chain describes who eats whom in the wild. Every living thing-from one-celled algae to giant blue whales-needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight. A rabbit eats the grass.

Detailed explanation-5: -Therefore, the food web depends on a constant supply of energy from producers and nutrients that are recycled by the decomposition of organisms. As food is passed along the food chain, only about 10% of the energy is transferred to the next level.
