Verified step by step guidance1
Understand the concept of a food chain: A food chain is a linear sequence of organisms where nutrients and energy pass as one organism eats another.
Identify the role of producers: Producers, such as plants, are organisms that can make their own food through photosynthesis, using energy from the sun.
Define primary consumers: Primary consumers are organisms that feed directly on producers. They are typically herbivores, meaning they eat plants.
Define secondary consumers: Secondary consumers are organisms that feed on primary consumers. They are often carnivores or omnivores, meaning they eat other animals or both plants and animals.
Clarify the energy flow: Primary consumers obtain energy by consuming producers, while secondary consumers obtain energy by consuming primary consumers. This illustrates the transfer of energy through the food chain.
