BIO 182 - Exam #4 Lisenbee
The biotic components of terrestrial ecosystems are referred to as - -Biomes
-Biomes - -groupings of plants and animals (communities) defined by a
dominant vegetation type
-Two abiotic factors - -Climate
Weather
-Climate - -prevailing, long-term weather conditions found in the area
-Weather - -specific, short-term weather atmospheric conditions of
temperature, moisture, sunlight, and wind
-What is the taxonomic grouping of humans / primates / great apes primarily
- -family Hominidae / Humans thought to be closely related to bonobos
(pigmy chimps)
-Net Primary Productivity (NPP) - -the total amount of carbon that is fixed
per year minus the amount of fixed carbon that is oxidized during cellular
respiration.
-aboveground biomass - -total mass of living plant tissues in a given area
(excluding roots)
-Tropical wet forests - -found in equatorial regions of the globe where temps
and rainfall are high and annual variation is low
-Subtropical Desert - -away from equator, characterized by high average
annual temps, moderate variations in temp and very low precipitation.
Low productivity
-Temperate Regions - -Moderate temperatures relative to the tropics and
polar regions, and temperatures vary greatly with the season
-Temperate Grasslands - -Includes steppes and prairies that form in
temperate regions with relatively low precipitation
-Boreal Forest / Taiga - -forms on subarctic lands just south of the Arctic
Circle. Characterized by very cold winders and short, cool summers;
temperature variation is extreme.
-Hadley Cell - -Major cycle in global air circulation. Responsible for the
pattern of moisture lost and dry environments around 30N and 30S latitude.
