D

Verified step by step guidance1
Understand the concept of a food chain: A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
Identify the roles within a food chain: Primary producers (usually plants) create energy through photosynthesis, herbivores (primary consumers) eat the plants, carnivores (secondary consumers) eat the herbivores, and tertiary consumers eat the secondary consumers.
Recognize the role of tertiary consumers: Tertiary consumers are typically carnivores that eat other carnivores, placing them higher up in the food chain.
Differentiate between decomposers and consumers: Decomposers break down dead organic matter, recycling nutrients back into the ecosystem, but they are not considered consumers in the context of a food chain.
Conclude that tertiary consumers are carnivores that eat other carnivores, as they occupy a higher trophic level in the food chain.
