Document Summary
Bsc2011 - integrated principles of biology 2 - lecture 27: ecology and climate. The study of house (environment) in which an animal lives. Also considers the disturbances in the are like hurricanes and fires. The scientific study of relationships between organisms and their environments. Test your hypothesis by doing an experiment. Ecological systems vary over space and time. Solar energy input and topography shape earth"s physical environments. Population: this is multiple organisms from the same species in the same geographical region. Population dynamics, unit of evolution, demography, and sex ratios are studied. Community: multiple species interact in a given environment. Interactions among populations, species diversity, trophic dynamics, competition, and succession are looked at. Studies energy flux and nutrient cycling, primary productivity, and material fluxes. Biosphere: global processes (how climate change changes globally), includes biotic and physical systems, oceans, atmosphere, geology. All these organizations are not independent of each other. Variations in solar energy drive patterns of weather and climate.
