Question

explain how the terms in each set below are related.

1. heterotroph, omnivore, carnivore
2. food chain, food web, trophic level
3. decomposer, heterotroph, carnivore
4. autotroph, food chain, heterotroph

Explanation:

• For 14: A heterotroph is an organism that cannot produce its own food. Omnivores (eat both plants and animals) and carnivores (eat only animals) are types of heterotrophs.
• For 15: A food chain is a linear sequence of organisms where each is eaten by the next. A food web is a complex network of interconnected food chains. Trophic levels are the positions (e.g., producer, primary consumer) in a food chain or food web.
• For 16: A decomposer (e.g., fungi, bacteria) breaks down dead organic matter. It is a type of heterotroph. Carnivores are also heterotrophs (they consume other organisms).
• For 17: An autotroph (e.g., plants) produces its own food. In a food chain, autotrophs are the producers, and heterotrophs (consumers) depend on them for energy.

Answer:

• 14: Omnivore and carnivore are types of heterotroph.
• 15: Food chain is simple, food web is complex (interconnected chains), and trophic level is position in chain/web.
• 16: Decomposer and carnivore are types of heterotroph.
• 17: Autotroph is producer in food chain, heterotroph is consumer.
