Trophic levels
-
-
-
-
-
The population vary depending on how many of the tier below there are, E.g: If their is an abundance in level 2, level 3 may begin to rise, and level 1 will drop
water and carbon cycles
-
carbon cycle
carbon is cycled by biotic and abiotic factors, as well as microorganisms
-
How does carbon cycle
-
respiration
all living organisms respire, releasing carbon
feeding
when one organism eats another, the biomass is transferred from one to the other
-
Biomass
-
made by producers, passed down ( not much of it)
in a biomass pyramid, The biomass would decrease along each level, as Not every level will eat every organism in the prior level, so not all energy will be passed down. Also some will be lost naturally through processes like respiration
decomposition
-
when decay occurs without oxygen, anaerobic decay transpires. This produces methane
-
