Which process plays an important role in the biogeochemical cycles of carbon, nitrogen, and phosphorus?

a.) photosynthesis
b.) transpiration
c.) decomposition
d.) respiration

Decomposition is the process that plays an important role in biogeochemical cycles of carbon, nitrogen and phosphorus.

Decomposition is the process of breaking down the wastes materials and the dead remains of plants and animals to generate nutrients such as carbon, nitrogen and phosphorus for the soil.

Keywords: Decomposers,decomposition, importance of decomposition to an ecosystem.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
