Front

Explain the significance of food chains and food webs.

Back

Food chains and food webs illustrate the flow of energy and nutrients through an ecosystem, showing how different organisms are interconnected.

Front

What do the arrows in a food chain represent?

Back

The arrows in a food chain indicate the direction of energy flow from one organism to another, showing who eats whom.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy.

Front

Differentiate between herbivores and omnivores.

Back

Herbivores are animals that primarily eat plants, while omnivores consume both plants and animals.
