Honors Biology 1-2: Species, Populations, & Communities

This video focusses on how Biological species interact as populations and communities. It highlights the learning goals of:
a. Distinguish between the different levels of ecological organization from species to the biosphere
b. Analyze data that depict changes in the abiotic components of an ecosystem and changes in the biotic components of an ecosystem over time (e.g., percent change, average change, correlation and proportionality). Evaluate claims of possible relationships between the changes in the abiotic components and the biotic components of the environment.
c. Explain the difference between exponential and logistic growth patterns and be able to relate these to the current pattern of human population growth
d. Describe how density dependent and density independent factors influence population growth
e. Describe the different ways that populations can interact over time
- Predator-prey interactions
- Competition (competitive exclusion)
- Symbiosis (parasitism, mutualism, commensalism)
