water and carbon cycles
Calcium hydroxide Ca(OH)2 (called slaked lime)Added:Even more 'naturally occurring' is Calcium carbonate, CaCO3 , which is the main component of shells of marine organisms, snails and eggshells. Calcium carbonate (commonly called limestone) is the active ingredient in agricultural lime as 'anti-acid'.

The two main phases of cell cycles are the interphase and the mitotic phase.
Hydrogen -> Helium
The flow of a nutrient from the environment to living organisms and back to the environment. Main reservoir for the nutrient is in the environment.
Recessions and periods of economic growth as the efficient response to exogenous changes in the real economic environment.

what are the two main types of environment
Peridotite rocks are coarse-grained, dark-colored igneous rocks. They are the main source of all chromium ore and naturally occurring diamonds. Their magnesium content helps mitigate global warming.
what are the two main types of environment
It is the main idea of the story
Yes - and no. Carbon Dioxide occurs naturally in the atmosphere. It's a waste product of respiration. However - it's also a waste product of many industrial processes. Since humans are responsible for ALL industrial processes - WE are the ones causing a build-up of greenhouse gasses !
