California State Standards •Students will know a vital part of an ecosystem is the stability of its producers and decomposers. •Students will know that at each link in a food web some energy is stored in the newly made structures but much energy is dissipated into the environment as heat. This dissipation may be represented in an energy pyramid. •Students will know how water, carbon, and nitrogen cycle between abiotic resources and organic matter in the ecosystem and how oxygen cycle through photosynthesis and respiration. •Students know how fluctuations in population size in an ecosystem are determined by relative rates of birth, immigration, emigration, and deaths. •Students will know how to analyze changes in an ecosystem resulting from changes in climate, human activity, introduction of nonnative species, or changes in population size. •Students will know that biodiversity is the sum total of different kinds of organisms and is affected by alteration of habitat.
