What is an organism that relies on other organisms for its food and energy supply; also called a heterotroph?

Consumer

Consumers are organisms who rely on others and CONSUME others to gain energy and nutrients.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

this is a good question! i'll do some research and come back when i have the answer!
