the organisms rely on each other for survival.
PGAL (aka phosphoglyceraldehyde) is a chemical compound that occurs as an intermediate in several central metabolic pathways of all organisms.
heterotrophsFungi are not autotrophic actually they are heterotropic
A community of organisms together with their physical environment, viewed as a system of interacting and interdependent relationships and including such processes as the flow of energy through trophic levels and the cycling of chemical elements and compounds through living and nonliving components of the system. hope this helps
Researchers interested in the evolution of eukaryotic cell division have observed in modern organisms what they believe are mechanisms of division intermediate between the binary fission of bacteria and mitosis as it occurs in most eukaryotes. These schematic diagrams of a proposed evolutionary sequence do not show cell walls.

Interdependent relationships involve to organisms that rely on each other and both benefit from the other in equal ways.
ecosystem
Stabilizing selection occurs when organisms with intermediate phenotypes are selected for.
Symbiosis is the relationship between two different species of organisms that are interdependent and each benefits from the other.
Mutualism is the relationship between two different species of organisms that are interdependent and each benefits from the other.
Interdependent organisms that live together defines a community for an animal. The community can also be called a habitat or an ecosystem.

the Calvin cycle of photosynthesis requires CO2 (carbon dioxide) organisms that are heterotrophs, like us, which cannot produce their own food consume autotrophs like plants, which do produce their own food. a by-product of cellular respiration is CO2 a by-product of photosynthesis is O2 organisms like us need O2 to live organisms like plants need CO2 to live (and to support us in life--we eat them because they have sugar [i.e., glucose])
The organisms in the aphotic zone depend on the organisms in the photic zone above to die, then drift down into the deep to provide food for the organisms down in the deep. I believe that the dependence of the photic organisms upon the aphotic organisms has to do with the necessity of breaking down the biomaterials and recycling the nutrients back into the system.
