SLS Bio11 Ecology MW

carrying capacity the number of living organisms that a region can support without environmental degradation
cellular respiration what cells do to break up sugars into a form that the cell can use as energy
chemical equation a balanced chemical equation shows how many of what molecules react, how many of what molecules result
climax community ecological community that has reached the final stage of ecological succession
commensalism relationship between two organisms in where one benefits and the other is neither benefited nor harmed
consumer an organism that generally obtains food by feeding on other organisms or organic matter
cyclic population growth occurs when there is a low amount of population, food is very high, & the population explodes
decomposer an organism, especially a soil bacterium, fungus, or invertebrate, that breaks down organic material
density-dependent factors where effects on size and growth of population vary with the population density
density-independent factors where effects on size and growth of population are not influenced by population density
ecological succession gradual process where ecosystems change and develop over time; nothing remains the same and habitats are constantly changing
energy flow movement of energy around an ecosystem by biotic & abiotic means
exponential growth where the population keeps growing and growing (no limiting factors)
logistic growth where the population is limited by limiting factors such as food shortage and shortage of shelter and space
mutualism symbiotic relationship that is beneficial to both organisms involved
parasitism non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host
photosynthesis process where green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
pioneer species durable species who are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession
population all the organisms of the same group or species, which live in the same geographical area (ability to interbreed)
producer organisms that make their own energy through biochemical processes
products something manufactured by an organelle
pyramid of energy graphical model of energy flow in a community
reactants substance taking part in a chemical reaction
steady state state where matter is flowing and all components remain at a constant concentration
symbiosis relationship between two different species of organisms that are interdependent; each benefits from the other
