Describe gastrulation. Why are the three layers important in development?​

Explanation:

Cells in each germ layer differentiate into tissues and embryonic organs The ectoderm gives rise to the nervous system and the epidermis, among other tissues

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)

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
