What is Photosynthesis?
Photosynthesis is the conversion of solar energy to chemical energyto be used as food it can be carried out by plants, algea, and some bacteria
What are Tropic levels?
Tropic levels are catagories of organisms defined by how the organisms gain energy.
What is Biomass?
Biomass is the total mass of living organisms in a defined group
What is Trophic efficency?
Tropic efficency is the measure the amount of enrgy or biomass that is passed down from one organism to the next
What is Bioaccumualation?
Bioaccumualation isa process in which materials especially toxins are ingested by an organismat a rate greater than they are elimenated
What is Biomagnification?
Biomagnification is the increase of concentration on the toxins as it moves from one tropic level to the next

What is Fermentation?
Fermentation is the process of using yeast or bacteria to convert sugar or other carbohydrates into an acid
What are green house gasses?
Green house gasses are gasses that go to the atmosphere weaking our ozone layer hence being more prominent to sunlight. Ex: carbon
What is Green house effect?
Green house affect is when gasses such as carbon go into our atmosphere therefor damaging the ozone layer as the gases cannot escape. Increasing the amount odf sunlight in a given area
What is acid precipitation?
Acid precipitation is when carbon dioxide is put into the atmosphere and goes throught the water cycle this event makes the Carbon dioxide become sulfric asid when percipitation occures
