Unformatted text preview: ntertidal zone - area that is periodically submerged & exposed by tides P elagic biome - phytoplankton & zooplankton are dominant; ocean- many freeswimming animals present C oral reefs - photic zones; require high O2 content M arine Benthic zone - sea floors; dark & cold 17. Vertical stratification is important; Upper canopy= low tree stratum-shrub understory-ground layer of herbaceous plants-forest floor-root layer Terrestrial biomes usually grade into one another, layer of intergradation= ecotone Biomes are dynamic and disturbance, rather than stability, is the rule. 18. T ropical forest - 200-400 cm rainfall, intense competition for light, greatest animal diversity D esert - at 30 degrees north and south; low rainfall, vast temperature ranges S avana - Equatorial and subequatorial; drought resistance grasses and few trees. Most prominent herbivore is insects C haparral - mid latitude coastal regions; rainfall highly seasonal. Dominated by shrubs and trees; has deer, goats, and a variety of small animals T emperate grasslands - plains and prairies; rainfall highly seasonal. Mainly grasses and forbs; has large grazers (bison) and burrowing animals C oniferous forest s- largest terrestrial biome on Earth; contains moose, brown bears, Siberian tigers, and birds migrate. Includes terrestrial rainforests; dominant plants are cone bearing trees T emperate broadleaf forests - mainly mid-latitudes of northern hemisphere; main plant is the deciduous tree, mammals hibernate and birds migrate T undra - Covers expansive areas of the Artic; winters long and cold-summers short. Contains lichens, grasses, and forbs; has large musk, ox, and reindeer. Predators are bears, wolves, and foxes 19. Climate determines why a particular terrestrial biome is found in a certain area. 20. Hurricanes, fires, etc. can affect where biomes exist Chapter 53: Population Ecology 1. P opulation ecology - the study of populations in relation to their environment, including environmental influences on population density and distribution, age structure, and variations in populati...
