Food of life!

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Food is the basic requirement of all living organisms including animals. Food is required not only to satisfy the hunger of an animal but it is needed to regulate the energy flow in animals. Animals need energy to perform daily activities.

If we take an example of wild animals- an herbivore like deer requires a lot of energy to escape from its predators. On the other hand, a predator like a leopard also needs tremendous energy to chase its prey and hunt.

The birds that live on or near water have adapted to be able to find food during the entire year. Waterbirds such as herons, cranes, ducks, loons, geese, grebes, and coots dine on combinations of water bugs, aquatic vegetation, small fish, invertebrates, frogs, seeds, grains, and nuts.
