Verified step by step guidance1
Understand the concept of a food chain: A food chain represents the flow of energy and nutrients through an ecosystem, starting with primary producers and moving through various levels of consumers to decomposers.
Define the roles in a food chain: Primary producers (e.g., plants) create energy through photosynthesis. Primary consumers (herbivores) eat the producers. Secondary consumers (carnivores or omnivores) eat primary consumers. Apex predators are at the top of the chain, and decomposers break down organic matter.
Identify the term 'intermediate consumer': This refers to an organism that is not at the base (primary producer) or the top (apex predator) of the food chain but occupies a middle position, typically feeding on primary consumers.
Match the term 'intermediate consumer' with the correct role: A secondary consumer fits this description because it feeds on primary consumers and is not at the top of the food chain.
Conclude that the correct answer is 'secondary consumer,' as it aligns with the definition of an intermediate consumer in a food chain.
