Honors Biology Study Guide Test 2 Fall: Ecology Ecological Interactions Ecosystem. Abiotic v. Biotic Niche vs. habitat Intra- & Inter-specific competition Ms. Z Population vs. Community Fundamental vs. realized niche Energy Flow: where does energy come from? Energy Conversion rates Ecological Pyramids Food chains vs. webs: predict consequences of changes Ecological Relationships Producers v. Consumers Autotrophs v. Heterotrophs Symbiotic Relationships Decomposers v. detritivores Competition Competitive Exclusion: what happens as a result? Fundamental v. Realized Niche Adaptations o Structural/morphology o Behavior: how an organism acts in response to a situation o Physiological: how the body functions Populations Examples of adaptations organisms have evolved to survive and maybe reproduce? Natural Selection Main three features: size, distribution, density Closed vs. Open populations Population dynamics: natality, mortality, emigration, immigration Population Models: Types of Curves & phases of growth curves o Logistic vs. Exponential Carrying Capacity? r-strategists vs. k-strategists Density-independent factors & Density-dependent factors & Limiting Factors Examples Biogeochemical Cycles Types: ex. H2O, C, P, N How does energy flow through ecosystems? What do these factors do to a population? How do materials cycle within environments between biotic and abiotic features? Why is water important to living things? Random Terms: Succession & pioneer species Biodiversity Photosynthesis vs. cell respiration Keystone Species Honors Biology Specialists v. Generalists Humans impact on the environment: two examples Study Guide Test 2 Fall: Ecology Ms. Z
