Botany - Ecosystem Question with Solution | TestHub

In nature, there is a need for continuous recycling of mineral which has have been removed from nature or environment, so some nutrient cycles are operated in nature. These cycles are mainly divided into 2 categories as gaseous cycles (like carbon cycle) and sedimentary cycles (like phosphorous cycle). There are two major and important differences between carbon and phosphorus cycle which are:
$\left(\mathrm{a}\right)$Atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs.
$\left(\mathrm{b}\right)$Gaseous exchanges of phosphorus between organism and environment are negligible, where the carbon inputs are prominent.
