1) A food is something that provides nutrients. ... energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.
2)Plants have leaves, roots, stem, flowers as their parts. We consume almost every part of the plant (root, stem, leaves, flowers, fruits, etc) as food. Fruits, vegetables, grains, seeds, herbs, are the food we eat that are obtained from the plant sources.
3) Animals that eat plants exclusively are herbivores, and animals that eat only meat are carnivores. When animals eat both plants and meat, they are called omnivores. ... These carnivores may eat insects and worms. Carnivorous animals have strong jaws and sharp teeth to enable them to tear and rip prey.
4) Scavengers can be animals such as birds, crabs, insects, and worms. They can be also called as detritivores. Decomposers are manly fungi. Earthworms and bacteria are also decomposers.
