Environmental Biology Test Gross primary productivity Rate at which an ecosystem’s producers capture and store a given amount of chemical energy as biomass in a given length of time Habitat Refers to a place or type of place where an organism or population of organisms lives Refers to the location and conditions of an environment in which a species lives Ex: dolphin in the ocean Nitrogen fixation The process of converting atmospheric nitrogen gas into forms useful to plants by lightening, bacteria and/or cyanobacteria. It is part of the nitrogen cycle Eutrophic Refers to a lake with a large or excessive supply of plant nutrients, mostly nitrates and phosphates Refers to a lake that has high primary productivity and is subject to algae blooms (poor water conditions) Rain shadow effect Refers to the effect of low precipitation on the leeward side of a mountain when prevailing winds flow up and over a high mountain or range of high mountains, creating semiarid and arid conditions on the leeward side of a high mountain range The rain cannot make it over the to the leeward side, making it arid or semiarid Upwelling A result of La Nina Movement of nutrient-rich bottom water to the ocean’s surface It can occur far from shore but usually takes place along certain steep costal areas were the surface layer of ocean water is pushed away from shore and replaced by cold, nutrient-rich bottom water The prevailing winds blow/push warm water westward allowing the cold nutrient-rich bottom water to come to the coast This creates a very biodiverse environment because the conditions created are better suited for different types of species
