BSC 101 Lecture Notes - Lecture 10: Arizona Transition Zone, Commensalism, Parasitism
Document Summary
Section 4. 3a and 4. 3b: how organisms acquire resources and resource requirements. Section 4. 4: changes in environmental factors and resources. Section 5. 3: how organisms interact: competition, keystone species, mutualism, commensalism, parasitism. These notes represent a detailed interpretation of the professor"s lecture. Gradebuddy is best used as a supplement to your own notes, not as a substitute. Carrying capacity: how much a habitat can sustain their population size with resources available at the time. Recall that a community consists of multiple populations of many species living in the same location. Species diversity: the number and density of a species in one location. (biological census). Transition zone: a location where the biological world and environmental conditions of the adjacent habitats blend together. The conditions of the blended habitat support species and contain ecological niches found in habitats on both sides of the zone. Recall that an ecosystem is made up of multiple communities and habitats: identified using dominant features.
