Food Webs – Who Eats What?

“When we try to pick out anything by itself, we find it hitched to everything else in the Universe.”

John Muir, naturalist, explorer, and writer (1838-1914)

Paraphrased: When one tugs at a single thing in nature, he finds it attached to the rest of the world.

Who Eats What?

A food-web is several food-chains connected together.

A food-chain only follows just one path as animals find food.

For example:

1) Leaves of plants are eaten by caterpillars, and

caterpillars are eaten by birds.

2) Flower nectar is eaten by butterflies, butterflies are eaten by lizards and lizards are eaten by birds.

3) Both flower nectar and pollen are eaten by bees, bees are eaten by assassin bugs, and assassin bugs are eaten by birds.

All living things need food to give them energy to live.

All plants and animals need food, which provides the energy they need to grow and for animals to move. A food-chain shows how each living thing gets its food. A food-chain always starts with a green plant. All plants are producers. Plants are eaten by animals. All the animals in the food-chain are consumers.
