Document Summary
Hierarchical: individuals/organism > population > community > ecosystem. Ca current - 30 degrees n - north pacific subtropical gyre. Biotic factors are living components of an ecosystem such as other living organisms, living food. Abiotic factors are non-living components of an ecosystem afecting an organism such as temperature, light, moisture, air currents etc. Consists of all organisms in community and all abiotic factors with which they interact. The law of physics and chemistry apply to ecosystems, particularly regarding the conservation of energy. Energy is conserved by degraded to heat during ecosystem processes. The weather in some location averaged over some long period of time. Depends on the tilt of the earth, which is retained throughout the. Seasons (annual variations in weather) exist in the northern and. Southern latitudes and hinges on which latitude is receiving more direct solar radiation. Climate diagrams can be used to get a good idea of seasonal weather patterns.
