I will give brainliest Convoluta worms hatch in early spring. They crawl about in the mud feeding on algae, which find their way into the skin of the worms. There they prosper as they worms feed on the sun-warmed surface mud.

The worms become greener and greener as they mature. Gradually their mouths seal shut, leaving only an internal garden of algae to provide them with food. As winter approaches, their food supply is exhausted, and the worms grow pale again. They lay their eggs in the mud just before they starve to death.

How do you think both worms and algae benefit from this relationship? WHY??

1. seamount a raised footwall block between normal fault creates this 2. syncline break between rocks where a hanging wall rises relative to a footwall 3. hot spring on rolling hills, this a dip between hills 4. volcanic neck created when a block with hanging walls slips down between normal faults 5. caldera underwater volcano that never reaches above sea level 6. horst natural hot water on earth's surface containing many minerals 7. graben underwater volcano whose top is eroded flat by waves 8. crater less than a mile in diameter; looks like a bowl at the top of a volcano 9. guyot magma that filled the central vent that remains after the volcano has eroded 10. reverse fault over 1 mile in diameter; looks like a bowl over a volcano
