11-2 What are consumers?
Aim: What are consumers?
OBJECTIVE: Identify different feeding levels of consumers.
Key Terms
consumer: organism that obtains food by eating other organisms
herbivore: consumer that only eats plants
carnivore: consumer that only eats animals
omnivore: consumer that eats both plants and animals
scavenger (SKAV-ihn-juhr): animal that only eats dead organisms
cellular respiration: process by which a cell releases energy from food molecules
Lesson Summary
• Many organisms are consumers, or heterotrophs.
• Consumers that eat plants are herbivores.
• Consumers that eat animals are carnivores.
• Consumers that eat both plants and animals are omnivores.
• Primary consumers are animals that eat producers.
• Secondary consumers are animals that eat primary consumers.
• Tertiary consumers are animals that eat secondary consumers.
• Cellular respiration is the process by which organisms release the energy contained in food.
Byproducts of cellular respiration are water and carbon dioxide.
