1 of 7
Draw a diagram for the carbon cycle
:
2 of 7
Explain the decompostion stage of the carbon cycle
decomposers break down carbon compounds in dead organisms by secreting ezymes they then absorb the products of digestion to use in respiration, this feeding method is called saprobiontic nutrition
3 of 7
What is the name for the decompostion of nitrogen compounds? what is the product?
ammonification, produces ammonium compounds
4 of 7
what happens during dentrification?
dentrifying bacteria use nitrates to repire anerobically which produces nitrogen gas
5 of 7
how is atmospheric nitrogen reduced to ammonia to be used by plants?
reduced by rhizobium bacteria founds in root nodules of leguminous plants. have mutalistic relationship as provide plants with nitrgoen whilst plants provide carbohydrates to them
6 of 7
What is nitrification?
nitrifying bacteria turn ammonium compounds to nitrites then Nitrobacter turns them to nitrates
