Document Summary

Climatic: temperature cold = less biodiversity, water availability change b/w wet/dry environments, modify continents, wind churn water, keep planet at constant t, light more c = higher t. Non-climactic: salts minerals, allow for biochemical rxns, ph 7 - 7. 5 to maintain life. Organism becomes better suited for its environment. Better adapted = more likely to survive / reproduce. No photosynthesis occurs b/c < 1% light penetrates. Inhabitants must be able to live in complete darkness. Oceans: horizontal oceanic zone, freshwater: horizontal limnetic zone. Ecological region @ lowest level of aquatic environments. Oceans: horizontal oceanic zone, freshwater: horizontal limnetic + littoral zone. Layer lining body of water, includes: sand bottoms, rock outcrops, corals and bay mud. Variation of life forms w/i one ecosystem or entire earth. Measures health of system, indicates threat of extinction. Total mass of living matter in one area at one time. (mass / unit area) or total mass in community.
