Ecology is the study of... - CORRECT ANSWER the relationship between an organism
and its environment & involves scientific study of the interactions determining the
distribution and abundance of organisms
Levels of Ecology (in order from biggest to smallest) - CORRECT ANSWER biosphere,
ecosystems, communities, populations, organisms
Biosphere - CORRECT ANSWER the sum of the surfaces, atmosphere and
hydrosphere of the earth which is occupied by lining organisms
Biomes - CORRECT ANSWER major habitat; aquatic, forests, grasslands, wetlands
Aquatic biomes - CORRECT ANSWER found within a body of water; includes
freshwater and marine
Freshwater - CORRECT ANSWER defined by very low concentration of salt; includes
ponds, lakes, streams and rivers
Marine - CORRECT ANSWER defined by a high concentration of salt; includes oceans
and estuaries
Forest biomes - CORRECT ANSWER dominated by trees; includes tropical, temperate,
taiga
Tropical forests - CORRECT ANSWER most diverse of all ecosystems; lacks seasonal
climate, but can have wet and dry seasons
Temperate forests - CORRECT ANSWER includes deciduous and coniferous forests;
has a seasonal climate
Taiga forests - CORRECT ANSWER northernmost forests with seasonal climate
including long winters and short summer: mostly coniferous trees
Grassland biomes - CORRECT ANSWER are dominated by grasses and are mostly
devoid of trees and shrubs; includes temperate & tropical grasslands
Temperate grassland - CORRECT ANSWER present in temperate climates
Tropical grasslands - CORRECT ANSWER found in warm or hot climates
, Wetland biomes - CORRECT ANSWER are dominated by aquatic vegetation and
poorly draining soils; includes bogs, fens, marshes, & swamps
Bogs - CORRECT ANSWER wetland which accumulates dead plant material
Fens - CORRECT ANSWER wetlands with grasses and mineral rich water
Marshes - CORRECT ANSWER wetland dominated by emergent vegetation
Swamps - CORRECT ANSWER wetland dominated by trees
Ecosystems - CORRECT ANSWER the ecological level at which biotic and abiotic
elements interact within a biome & the flow of energy and chemical materials occurs
(shaped by interactions of abiotic climate, elevations & topography w/ biotic elements)
Communities - CORRECT ANSWER the ecological level that are the assemblage of
different populations of flora and fauna species in an area (Ex: all species living on a
dead tree, all species living in a pond)
Populations - CORRECT ANSWER the ecological level that are groups of organisms of
the same species occupying a particular space at the same time
Organisms - CORRECT ANSWER the ecological level that are individual members of a
population; can either be a producer or consumer
Producers - CORRECT ANSWER organisms which produce food or biomass through
the process of photosynthesis
Consumers - CORRECT ANSWER organisms which obtain food and energy through
the consumption of other organisms
Photosynthesis - CORRECT ANSWER the process by which green plants and algae
convert sunlight to plant tissue from carbon dioxide and water (requires the presence of
chlorophyll, green pigments, to absorb light)
Niches - CORRECT ANSWER describe how organisms match specific environmental
conditions and respond to distribution of resources and competitors
Niches can be influenced by... - CORRECT ANSWER competition with other species,
predation, parasitism, mutualism
List the ecological interactions btw organisms - CORRECT ANSWER mutualism,
commensalism, competition, predation
Mutualism - CORRECT ANSWER when two species benefit from ecological interaction
