1.In some cases humans may consume other animals as food. Sponges are not a good option. Why do you think they are inedible?

Sponges are made of material that is, first of all, hard to eat. Second of all, sponges don't provide many nutrients that would make eating the sponge worth it in the first place

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)
