Which of the following statements is true?

a)water and energy are not recycled in an ecosystem.
b)weathering is the main way phosphorous is recycled.
c)the total amount of energy in an ecosystem continuously increases.
d)the organism at the top of a food chain receives the most energy from the sun.

Option b

Explanation:

Phosphorous is an important component that is circulated throughout the earth. The phosphorous cycle passes through the soil, water and sediments.

Over time, rain and weathering releases phosphorous ions into the water and travels to reach the soil.

The plants take the phosphorous from the soil and water.This process is known as mineralization.

The phosphorous from the soil is also carried towards the ocean and then it gets inside the sediments.
