Document Summary

Definitions: ecology study of interactions between organisms and their environment, determining the distribution and abundance of those organisms. If trait is heritable, frequency in the population should increase: producer make their own food for energy, consumer eat other organisms to obtain energy, nutrient cycle consumption, decomposition, root uptake. Testing ecological hypotheses: observational experiments observing and describing, controlled lab experiments control and experimental group for comparison in lab, controlled field experiments control and experimental group for comparison in field. Absorb heat around equator, head north, cool down and fall back to south. Latent heat loss release of energy when water evaporates. Terrestrial biomes are defined by vegetation type: 9 different biomes (large biological community shaped by environment). Lentic ecosystems: lakes and ponds, effected by depth, water temperature, clarity and chemistry, spatial zones of a lake: Littoral zone macrophytes live here: pelagic zone open water, small animals live here, photic zone where the light goes to.
