Savanna and Grassland Biomes Answers

Savannas and grasslands are both open ecosystems dominated by grasses, and both are shaped by fire, grazing, and limited water. Savannas are usually tropical, with wet and dry seasons and scattered trees. Temperate grasslands generally have fewer trees and larger seasonal temperature changes.

Savanna plants have adapted to the long periods of drought in a variety of ways. Some savanna plants have the ability to store water. Other plants have long roots which allow them to reach the water table.

Burrowing animals and ground-dwelling birds are common in grasslands because there are very few trees in which birds and animals can take shelter. Burrowing also affords animals some protection from the fires and high temperatures that are common in grasslands during the dry season.

Wildfires prevent trees and shrubs from taking over, which helps keep savannas and grasslands open. They also return nutrients to the soil and encourage new grass growth.

Servals have long legs that help them move through tall grass and pounce on prey. Their large ears help them hear small animals hidden in the grass, and their spotted coats provide camouflage.
