CA State Standards addressed:
Ecology
- Stability in the ecosystem is a balance between competing effects. As a basis for understanding this concept:
- Students know biodiversity is the sum total of different kinds of organisms and is affected by alterations of habitats
- Students 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 know how fluctuations in population size in an ecosystem are determined by the relative rates of birth, immigration, emigration, and death
- Students know how water, carbon, and nitrogen cycle between abiotic resources and organic matter in the ecosystem and how oxygen cycles through photosynthesis and respiration
- Students know a vital part of an ecosystem is the stability of its producers and decomposers
Students know at each link in a food web some energy is stored in newly made structures but much energy is dissipated into the environment as heat. This dissipation may be represented in an energy pyramid.
