1. Producers: These are organisms like plants and algae that make their own food through photosynthesis. They form the base of the food chain.
2. Consumers: These organisms get their energy by eating other organisms. Examples include herbivores (eat plants), carnivores (eat animals), and omnivores (eat both plants and animals).
3. Decomposers: These organisms break down dead organisms and waste products, returning nutrients to the ecosystem. Examples include bacteria and fungi.
4. Herbivores: These are animals that eat plants, like deer, rabbits, and caterpillars.
5. Carnivores: These are animals that eat other animals, like lions, wolves, and sharks.
