What Is a Grassland Food Chain?

On an Africansavanna, zebrasgrazeon grasses. A lion creeps closer, hidden in the dry grass. The lion charges, capturing a zebra. Lions, zebras, and grass are part of a grassland food chain.

All living things needenergyto live and grow. They get energy from food. Plants and animals that live in the samehabitatare connected to one another by the flow of energy.

The energy in food chains begins with the Sun. Green plants use the Sun’s energy to make food through a process calledphotosynthesis.

Many animals get energy andnutrientsby eating plants. Animals use that energy to move, sleep, grow, and live. Other animals hunt for food. Their energy and nutrients come from theirprey.

Thîs îon îs gettîng ready to attack zebras on a savanna în Tanzanîa.
