The Carbon Cycle

?
What are detritivores?
Digest some waste material. Feed on detritus and increase surface area for saprobiotic organisms. Excrete waste products and aerate the soil.
1 of 6
What are saprobiotic organisms?
Microbes that live on detritus. Use extracellular digestion to absorb nutrients through active transport and diffusion. CO2 is released back into the atmosphere when they respire.
2 of 6
Carboniferous rocks
Contains 99% of the earth's carbon which is released by weathering.
3 of 6
Ocean
CO2 reserve that keeps atmospheric levels constant.
4 of 6
Feeding
Transfers complex organic molecules in producers to consumers.
5 of 6
Death and decay
Saprobiotic organisms break down complex molecules aided by detritivores and release simple organic molecules.
