Verified step by step guidance1
Understand the roles of different types of consumers in an ecosystem: primary consumers are typically herbivores that eat producers (plants), while secondary consumers are carnivores or omnivores that eat primary consumers.
Identify the characteristics of omnivores: they can consume both plants and animals, allowing them to function as both primary consumers (when they eat plants) and secondary consumers (when they eat animals).
Consider the role of herbivores: they primarily consume plants, making them primary consumers, but not secondary consumers.
Evaluate the role of decomposers: they break down dead organic material, recycling nutrients back into the ecosystem, but do not fit the role of primary or secondary consumers.
Analyze the role of carnivores: they primarily consume other animals, making them secondary or tertiary consumers, but not primary consumers.
