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
