Document Summary
Hypothesis: supposition or proposed explanation made based on limited evidence as a starting point for further investigation. Actual change in the dna of an organism. Carrying capacity: maximum number of individuals that the environment can support. Theory: system of ideas intended to explain something. Positive feedback: enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedback: new input results in opposite direction reduces any changes in the system, therefore helps stabilize it. Autotroph: self-feeders, organisms capable of making their own food. Heterotroph: must take in energy from outside sources, cannot make their own (i. e. animals) Species: group of interbreeding individuals capable of producing viable offspring. Keystone species: certain species have an especially large impact on a community. It may not be the most abundant species and may not be a top predator.
