Energy & Matter
Conservation of Energy & MatterEnergy/Matter can neither be created or destroyed, only transformed from one form to the other. Cycling of matter through ecosystems begins with incorporation of substances into bodies of living organisms from non-living reservoirs
materials pass from organisms that first acquire them into bodies of organisms that eat them until they complete the cycle and return to the nonliving world, through decomposition.

Matter Cycling Through Abiotic & Biotic FactorsMatter cycles continually through both biotic and abiotic components of ecosystems called biochemical cycles.
cyclic pathways involving biological, geological and chemical processes driven directly or indirectly by incoming solar radiation and gravity connect past, present, future forms of life. |
Photosynthesis & Cellular RespirationCellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
