Which is the final event that occurs when a star is forming?

the outer layer of the star expands

Explanation:

Gravity pulls gas and dust together. A protostar forms as mass increases. A black hole forms as the core collapses.

Hence, the final event that occurs when a star is forming is that nuclear fusion begins under high pressure.

Explanation:

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)

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)
