Ch 51-54 Ecology Test Topic Study Guide: Multiple choice and Writing
Topic study guide: Remember that this list is NOT all-inclusive. Try to list as many things about each topic as you can, without the assistance of your notes.
Organization/Characteristics/Examples (Biosphere through organism)
Population density
Dispersion – random, uniform, clumped
Population growth – types, curves (shapes) (Gause)
K-selected vs. r-selected organisms – features/characteristics
Survivorship – Type I, II, III – characteristics
Age structure
Consumers (different levels), producers, heterotrophs, autotrophs, carnivore, herbivore, detrivore, saprobe, decomposer
Ecological niche, habitat, limiting factors
Primary and secondary succession
Competition – intraspecific, interspecific – competitive exclusion
Plant/animal defenses – chemical/ physical (mimicry, camouflage, etc.)
Mycorrhizae – mutualism, commensalism, parasitism, predator/prey
Energy flow through an ecosystem
Food webs, food chains, trophic levels, energy pyramid, pyramid of numbers, biomass pyramid
Net primary productivity
Biogeochemical cycles – carbon, water, nitrogen – parts/steps
Biomes – characteristics (tundra, taiga, chaparral, desert, savanna, temperate rain forest, tropical ran forest, etc.)
Aquatic biomes – zones of water (depth vs. distance), characteristics; types (estuary, river, lake, ocean, etc.), marine snow
