Flexi Says: Tropical grasslands are tropical biomes with relatively low rainfall where the primary producers are grasses. Tropical grasslands are found mainly in Africa, where they are called savannas. They have high temperatures year-round, but relatively low precipitation. Moreover, most of the precipitation falls during a single wet season, leaving the rest of the year very dry. The climate during the dry season is disastrous to animal and plant life as there is less amount of water and food. However, during the wet season, there is a good amount of rainfall that leads to the sprouting of healthy plants. This gives plenty of food and water for the survival of animals.
