1 An Introduction To Ecology Chapter 52

2 Ecology – study of interactions between organisms and environment. Consists of abiotic (nonliving; i.e. temperature, light, etc) and biotic (living) factors.

4 Population – group of individuals of same species living in an area. Community – all organisms of all species that live in an area. Ecosystem – above plus abiotic factors. Biosphere – sum of all ecosystems.

6 Distribution affected by temperature, water, sunlight, wind, and rocks and soil. Type of each will determine what can live there.

8 Temperature and water are biggest factors. Biomes – major types of ecosystems. Determined by proximity to equator, closeness to ocean, mountains, etc.

10 Aquatic biomes 2 types – marine and freshwater. Stratified vertically – photic zone (light) and aphotic zone (little light). Bottom of aquatic is benthos – food is detritus that falls from above.

12 Freshwater – close to shore – littoral zone. Open water – limnetic zone. A Lakes classified by nutrients – 1 eutrophic – shallow and nutrient- rich; 2 oligotrophic – deeper and nutrient-poor.

15 B Wetlands – area covered with water; supports plants. C Estuaries – area where freshwater meets ocean. Intertidal zone – land meets water. D Coral reefs – dominated by coral.

19 E Oceanic pelagic biome – away from shore. Abyssal zone – lowest part of benthos; deep-sea hydrothermal vents help chemoautotrophic organisms.

21 Terrestrial biomes Defined vertically from the canopy at top to the permafrost at the bottom. A Tropical forest – little light reaches ground because of deep canopy. Rainfall determines life in area.

23 B Savanna – scattered trees and grasses. Fire helps increase diversity. Has rainy season. C Temperate grassland – seasonal drought, fires prevent tree growth. Most used for farming.

26 D Deserts – sparse rain, some are cold. Plants have structures to allow survival (i.e. water storage, alternative forms of photosynthesis) E Chaparral – evergreen shrub; long, hot, dry summers with fires.

29 F Temperate deciduous forest – small mammals, leaves fall during autumn. G Taiga – cone-bearing trees, trees have needles. H Tundra – permafrost covers ground, low diversity.
