Calcium Cycle By: Chaney Durham and Brittany Ford
From the biosphere… • Calcium enters from biosphere in dust or from organisms • Like phosphorous, there is no gaseous state so it does not stay in the atmosphere • When animals die, the calcium in their bodies are decomposed and go into soil
In the soil… • Water can carry calcium to or from soil through weathering • When in the soil, calcium is in an insoluble form until it is broken down by microbes into a usable form • Mineralization can store calcium in rocks • Calcium can be returned from root leakage • Calcium can be absorbed by plant roots
In plants… • When absorbed by plants, calcium is now in an organic state • The calcium can continually be recycled between the plant roots and soil • OR herbivores can eat the plants or drink the water and the calcium returns to the biosphere • If the plant or animal dies, decomposers break down the organism and calcium is returned to water or soil
Importance to Life • Calcium is a mineral necessary for life • In early life, calcium helps build strong bones and teeth • Helps with muscle contraction and other body processes • Plants need calcium to help in cell wall development and their metabolism; stronger cell walls protect from pathogens
