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 different trophic levels: The main trophic levels are primary producers, primary consumers, secondary consumers, and tertiary consumers.
Define primary producers: These are typically plants or algae that produce energy through photosynthesis and form the base of the food chain.
Define primary consumers: These are organisms that eat primary producers. They are usually herbivores, meaning they consume plants or algae.
Recognize that herbivores, which eat plants, occupy the primary consumer level in a food chain, as they directly consume the primary producers.
