Document Summary
I1) given a scenario, identify the level of ecological organization. Explain why a population perspective" is important in our study of ecology. Organismal: how do individuals interact with each other & their physical environment. Explore morphological, physiological, behavioural adaptations that allow individuals to live in a particular area. Communities: nature of interactions b/t species & the consequence of those interactions. How groups respond to fires, floods & other disturbances. Ecosystems: study how nutrients move among organisms & through the surrounding atmosphere through sold or water. Look at impact of pollution & increased temperature on disturbances. I2) describe & identify factors that affect species distribution (range) & dispersion. Abiotic factors: include chemical, oxygen levels, ph, light availability, climate. Biotic: presence or absence of other species affects interactions & changed distributions- predators, competitors, pathogens, invasive species results in new biotic interactions. I3) explain why population density is more informative that population size.
