Carbon cycle

Nutrient cycles

nutrient recycling

allows elements like carbon and nitrogen to exchange between living and non living parts ecosystem(allows nutrients to be reused)

what is the function carbon cycle

so carbon dioxide can be converted to carbon in living things(carbs proteins lipids)

description carbon cycle(plants)

plants absorb co2 from atmosphere by photosynthesis to make glucose(carbs)(also break down glucose to release co2)fossil fuels form which stores carbon. combustion results co2 being released into atmosphere.

description carbon cycle (animals)

animals consume co2 by eat plants. animals return carbon back into atmosphere by respiration. animals die and decay release co2 into atmosphere. bacteria and fungi act decomposers return co2 back into atmosphere(also carry out respiration)

processes involved carbon cycle.

photosynthesis respiration decomposition combustionb

what function of nitrogen cycle(why do organisms need nitrogen)

living things use nitrogen for the formation of protein and nucleic acid(converts nitrogen gas into forms living things use)

nitrogen cycle description first 2 steps

gas converted into nitrates by nitrogen fixing bacteria in the soil(nitrogen fixation) lightning also does this. nitrate in soil absorbed by roots of plants by active transport form plantprotein (or DNA or RNA)

what are nitrates

usable form nitrogen(minerals in soil)

nitrogen cycle next steps

plants consumed by animals(plant to animal protein) animals plant die decompose(by fungi bacteria) which release nitrogen in soil called ammonia. nitryfying bacteria in soil now convert ammonia into nitrites and then nitrates. some nitrates absorbed by plants some back into nitrogen gas

what also forms ammonia

excretion urine

nitrogen fixation

when nitrogen gas is converted into nitrates by nitryfing bacteria

what is the name of the process where nitryfyinng bacteria in soil convert ammonia into nitrites then nitrates

nitrification

how do nitrates convert back into nitrogen gas and what is this process known as

denitryfying bacteria and denitrification

decomposition

bacteria, that live in the soil, decompose dead plants and animals to produce ammonia

Nitrogen Fixation

he conversion of gas nitrogen,  to nitrates,

absorption

Once nitrogen fixation has occurred, plants will absorb the nitrates to make DNA, RNA, and protein

Nitrification

the conversion of ammonia, into nitrites,  and then into nitrates. by nitrifying bacteria
