The hydrologic cycle is different from other nutrient cycles in that water is not recycled, but flows one way through ecosystems.
a. the biotic part of the cycle plays only a small role.
b. the ocean is involved.
c. the soil is not involved.
d. the atmosphere is involved.

Option C

Explanation:

The hydrologic cycle or water cycle can be defined as the movement of water across earth. The per cent age of water on earth remains same so the amount of water that is evaporated is the amount of water which is precipitated.

The statement that the soil is not involved in the water cycle is wrong. Actually soil plays a major role in water cycle.

It is very important as it provides water to the plants, animals and other biotic factors. The water infiltrates through the soil and then moves to other places where the water is available.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
