Population growth using the exponential growth model a increases at a constant rate b has an increasing intrinsic growth rate c represents ideal conditions that rarely occur in natural populations d incorporates the carrying capacity of the population

ocean expansion, global warming is melting icebergs and causing water levels to rise.

equal distribution i think.

atp is used for energy.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
