JT016, yup!
Decomposers are usually bacteria or fungi that actually break down organic matter, while detritivores can be heterotrophs that feed on organic matter, or just consume the decaying organisms/not actual recycle the nutrients back into the ecosystem.
Your turn!

Thanks for the clarification!
What is an ocean dead zone, and what is 1 cause of a dead zone?

An ocean dead zone is a region of extremely hypoxic water with insufficient dissolved oxygen to sustain aquatic heterotrophs.
A cause of an ocean dead zone would be eutrophication caused by the input of a limiting nutrient (commonly nitrogen in the oceans).

Correct! Your turn :D

a. weather conditions
b. deforestation (affects amount of shade a body of water receives)
c. global warming

Okay, I'll accept that. A couple other factors include: changes in turbidity (which may be caused by changes in the rate of soil erosion (another possible effect of nearby deforestation)) and discharge of industrial coolant water (commonly from electricity generation).

Alright, let's keep this marathon rolling. What is nonpoint source pollution? Give an example of nonpoint source pollution as well.

Non-point source pollution is pollution that is caused by the diffusion of pollutants (I'm not too sure on the wording of that definition). An example would be runoff from a car, which would cause water pollution.

Yep, your turn.
