Concept:A savanna is a tropical grassland biome with scattered fire-resistant trees and many large herbivores.Explanation:Savannas receive moderate rainfall with a distinct dry season. Grasses are the dominant vegetation and provide food for large herbivores. Trees are few and scattered because drought, fire, and poor soils limit their growth. These trees survive fires due to adaptations such as thick bark and deep roots. The open environment allows large herbivores to move freely and graze on abundant grass. Carnivores also thrive by preying on these herbivores. Tropical rain forests have dense canopies and high rainfall, not scattered trees. Montane forests grow on mountains and become colder with altitude. Deserts receive very little precipitation and support sparse life. Therefore, the described biome is savanna.Answer:A. savanna
