Document Summary
When species appear outside of its range we"re very interested. Grey owl - normally extends to northern but also in southern ontario (1x) Ecology is derived from energy = currency by which org interact. Earth is bomboarded with energy but small proportion ends up in biomass of plants (1%) And into herbivores a small amt of biomass - (10%) then to others and others. Energy is important b/c quickly drops off to amt of total energy available. If nrg transfer efficient should see plant grows leaves it"s eaten right away. Nrg is limited especially for top predator so how they find nrg is important to their survival. Also why we don"t see top top top predators (min nrg available to sustain population) Autotrophs either thru photo or chem. Take c02 and water and turning into sugar 02. 1935 1st time to view a system this way : pond. All the mutual interactions are possible b/c of input of solar radiation.
