In the process of eating the remains of dead organisms and their wastes, earthworms aerate and fertilize the soil. They are also a source of food for
many birds, snakes, and insects. Which term best describes the earthworm's
role in its habitat?
A. Decomposer
B. Protist
C. Producer
D. Abiotic Factor

The answer is earthworms

Explanation:

Earthworms are a bigger decomposer that eats what's left of a dead animal and adds nutrients to the soil. I hope this helped! :D

As the person above me said, it is Decomposers

Explanation:

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
