Document Summary
> an ecosystem integrates the idea of systems thinking and how you think of an area. > negative feedback loops are more for things like density dependent, population regulation, stabilizing, etc. An example is a person who is in a bad mood and someone calms them down. > systems resists change and remains stable despite a disturbance. > an example of resistance, is being able to resist if someone pushes you and you don"t fall. > when we look at an ecosystem, we look at its: a) abiotic environment (water, soil minerals, atmospheric gases, etc), b) producers, c) consumers, d) decomposers. > succession is how ecosystems change over time: what two words have the same roots and come from the greek word okos? . > plants need sunlight, nutrients, water and co2. > the real limiting factors are often precipitation which limit production. > camels often sit down carefully, perhaps their joints creak.
