Ecosystem Types Flashcards
ecosystems in which an abundance of flora, or plants, is seen so they have a big number of organisms which live in relatively small space.
density of living organisms is high
Forest ecosystem
forests that receive a mean rainfall of 80 for every 00 inches annually
dense vegetation comprised of tall trees at different heights
Tropical evergreen forest
shrubs and dense bushes with broad selection of trees
has a large variety of fauna and flora
Tropical deciduous forest
few number of trees; majority are mosses and ferns
trees have spiked leaves to minimize transpiration
Temperate evergreen forest
located in moist temperate places that have sufficient rainfall
summers and winters are clearly defined
Temperate deciduous forest
situated before arctic regions
defined by evergreen conifers
during non-winters, it buzzes with migratory birds and insects
Taiga
located in regions that receive an annual rainfall less than 25
occupies 17% of all the land on our planet
low water availability and intense sunlight
vegetation is mainly shrubs, bushes, few grasses, rarely trees. leaves of the plants are modified to conserve water
Desert ecosystem
located in tropical and temperate regions
mainly compromise grasses; little trees and shrubs
a lot of grazing animals, insectivores, and herbivores inhabit this ecosystem
vegetation: grasses, plants, and legumes
Grassland ecosystem
Tropical grasslands
dry seasonally
few individual trees
large number of predators and grazers
Savanna
temperate grassland
devoid of large shrubs and trees
mixed grass, tall grass, and short grass
Prairies
biggest ecosystem
high amounts of minerals and salts
Marine ecosystem
relatively shallow part of oceans which lies on the continental shelf
Oceanic
deep of bottom water
profundal
bottom substrates
benthic
place between low and high tides
inter-tidal
tidal mouth of large river, where tide meets the stream
estuaries
underwater ecosystem characterized by reef-building corals
coral reefs
coastal wetlands that are flooded and drained by salt water brought by the tides
salt marshes
where chemosynthetic bacteria make up the food base
hydrothermal vents
covers only 0.8% of Earth’s surface and contains 0.009% of the total water
Freshwater ecosystem
Slow-moving or still water like pools, lakes, or ponds
Lentic
Fast-moving water such as streams and rivers
Lotic
places in which the soil is inundated or saturated for some lengthy period of time
wetlands
