Calcium cycle
What Is Calcium?
Entering the soil
-It is one of the mineral cycles in earth
-It shows how calcium is extracted from earth and living organisms
-It also shows how it is returned to earth
-Soft gray alkaline earth metal
-Chemical symbol Ca
-Atomic number 20
-Atomic mass 40.078 amu
-Water moves calcium to and from soil by weathering
-In the soil,calcium is broken down until its in usable form
-it can be stored in rocks
-It can return from root leakage
-It can be absorbed by plant roots
Calcium In Human Bodies
How it Begins
When In Plants
Steps Of The Calcium Cycle
-From birth to death calcium is an element for human being
-beside its presence in bones and teeth the mineralized tissues contain 99% of the body's calcium
-it is present in blood,fluids, within the cells of tissues such as muscles
-necessary for release of energy in muscular contraction for nerve transmission, regulation of heart
-When taken in by plants, calcium is in an organic state
-Can be recycled between roots and soil
-If herbivores eat the plant, calcium becomes biosphere
-If plant or animal dies, calcium is returned to water or soil
Step 1: Weathering Away of rocks that contain calcium carbonates
Step 2: Calcium flows into the ocean and stays there for years
Step 3: Eventually it returns to the land due to precipitation
-It enters the biosphere from organisms or dust
-The calcium in animals bodies are decomposed and enter soil when they die
Calcium Importance to Life
The Calcium Cycle
-In early life, it helps build strong bones and teeth
-Helps muscle contraction, body processes
-Plants need calcium to help cell wall and metabolism
-Calcium is a mineral necessary for life
