Which process plays an important role in the biogeochemical cycles of carbon, nitrogen, and phosphorus?
a) photosynthesis
b) transpiration
c) decomposition
d) respiration

Decomposition.

Explanation: The biogeochemical cycle cycle can be defined as the abiotic cycle such as carbon, nitrogen and phosphorous cycle.

The interaction between the abiotic components and biotic components aids in the availability of these nutrients into the soil.

The producers take nutrients from the soil and carbon dioxide from atmosphere for manufacturing food and when the plants and animals die the decomposers recycles the nutrients back into the soil.

So, decomposition is an important role in the biogeochemical cycles .

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
