Ecology Human Impact on The Environment and Ecosystems

Standards: BI.6.b.-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. BI.6.c.-Students know how fluctuations in population size in an ecosystem are determined by the relative rates of birth, immigration, emigration, and death. BI.6.d.-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.

Objectives: Describe how organic matter is cycled in ecosystems through different biological processes. Analyze the impact of human activity on ecosystems. Explain the various factors that cause population increases and decreases in an ecosystem.
