Explanation:

Classify each organism

• Producer: Organisms that can make their own food through photosynthesis (like plants). Seaweed, grass, and apple tree are producers.
• Consumer: Organisms that eat other organisms. Duck, hawk, ants, people, rabbits, bees, and beetle are consumers.
• Decomposer: Organisms that break down dead organisms. Bacteria and earthworm are decomposers.

• Producers (like plants) use photosynthesis to make their own food.
• The sun is the ultimate source of energy for most ecosystems (used in photosynthesis).
• Food chains combine to form food webs (a complex network of feeding relationships).
• The role of an organism in its ecosystem is called its niche.
• Decomposers break down dead organisms and return nutrients to the soil.
