Characteristics of oceanic zones
What is euphotic- sunny, high oxgen concentrations and life; bathyal- low sunlight, low oxygen content, less quantity of life; abyssal- very dark, cold, and very little life?
300
Location of coral reefs

Benefits of coral reefs
What is habitat for a variety of species, medicinal purposes, tourism and recreational activities, reduce the greenhouse effect?

Describe the steps of the nitrogen cycle
What is nitrogen fixation- bacteria converts atmospheric nitrogen to nitrogen that can be used by decomposers nitrification- nitrogen is transformed to a type that plants can use. assimilation- fixing it in the plant and animal can eat plant and therefore take up N. ammonification- break down N containing compounds and return N to soil. denitrification- bacteria convert N in an O2 poor environment back to atmospheric nitrogen?
500
nitrogen fixation vs. denitrification
What is coverting atmospheric nitrogen to a form that plants and animals are able to use (fixation); coverting nitrogen from ammonium to atmospheric nitrogen (N2) and returning nitrogen back to the atmospehre?
500
Effects of eutrophication
What is algal blooms, decrease in dissolved oxygen concentrations, and decrease in biodiversity?
500
Characteristics of lake zones
What is littoral- top section that recieves the most sunlight, limnetic- middle section that recieves little sunlight, profundal- that recive little/no sunlight and is located at the bottom of a lake or pond?
