In an ecosystem, what do primary consumers typically eat?
A
Decomposers
B
Other primary consumers
C
Producers such as plants and algae
D
Secondary consumers
Verified step by step guidance1
Understand the concept of trophic levels in an ecosystem. Trophic levels represent the feeding positions in a food chain, starting with producers at the base, followed by primary consumers, secondary consumers, and decomposers.
Recognize that producers, such as plants and algae, are organisms that can create their own food through photosynthesis. They form the base of the food chain and provide energy for other organisms.
Learn that primary consumers are herbivores or organisms that feed directly on producers. They rely on plants, algae, or other autotrophs for their energy and nutrients.
Differentiate primary consumers from secondary consumers, which are carnivores or omnivores that feed on primary consumers, and decomposers, which break down dead organic matter.
Conclude that primary consumers typically eat producers, such as plants and algae, as they occupy the second trophic level in the food chain.
