Verified step by step guidance1
Step 1: Understand the concept of primary producers. Primary producers are organisms that can produce their own food through photosynthesis or chemosynthesis. They form the base of the food chain in an ecosystem.
Step 2: Identify the savanna ecosystem. A savanna is characterized by grasslands with scattered trees and shrubs, typically found in tropical and subtropical regions.
Step 3: Recognize the role of grasses and scattered trees in the savanna. These organisms are autotrophs, meaning they use sunlight to produce energy through photosynthesis, making them primary producers.
Step 4: Evaluate the other options provided. Lions and hyenas are carnivores, termites and dung beetles are decomposers, and vultures and eagles are scavengers. None of these groups are primary producers because they do not produce their own food.
Step 5: Conclude that grasses and scattered trees are the primary producers in a savanna ecosystem, as they are the organisms responsible for converting solar energy into chemical energy through photosynthesis.
