Ecology Notes

Biomagnification A pollutant moves up the food chain It affects organisms at the top of the food chain the most.

Renewable resources Replenish themselves over time.

Freshwater zones Littoral: near the shore Limnetic zone: open water Benthic zone: lake bottom

Ocean zones Intertidal: shoreline between high and low tides. Like th elittoral zone Neritic zone: shore to edge of continental shelf Bathyal zone: open water down to about 2000 meters Abyssal zone: >2000 meters to bottom. No light

Terrestrial zones Polar: between poles and arctic or antarctic circle Temperate: between Arctic circle and Tropic of Cancer or Antarctic circle and the Tropic of Capricorn Tropical: from Tropic of Cancer to Tropic of Capricorn
