Term
Biome
Definition
A place characterized by the organisms that live there and the abiotic factors like rainfall and temperature. It can contain one or more ecosystems.
Term
Temperate grassland (land biome)
Definition
has small, seed eating mammals, large herbivores and few trees.
Term
Savanna (land biome)
Definition
large herbivores live and graze on grass here, scattered clumps of trees.
Term
Desert (land biome)
Definition
- plants grow far apart to reduce competition for water
- receives the lowest average yearly rainfall
- plants have fleshy stems and quick blooming flowers
Term
Tundra (land biome)
Definition
characterized by permafrost-(soil that stays frozen all the time which prevents rain from draining), no trees
Term
Temperte Deciduous Forest (land biome)
Definition
- most trees are deciduous (lose their leaves in the Fall to help conserve water so they can survive winter)
- soil is fairly rich and plants cover the forest floor
- animals eat nuts, leaves, and berries
Term
Coniferous Forest (land biome)
Definition
- contains conifers- trees that produce their seeds in cones and do not lose their leaves in Fall
- they conserve water in the winter with the help of needlelike leaves & a waxy coating on their leaves
- the trees block most of the light from the forest floor so few plants can grow
Term
Tropical Rainforest (land biome)
Definition
- most biologically diverse (the most different types of plants and animals)
- soil is wet and has poor nutrients
- receives the highest yearly average rainfall
- Plants on the forest floor have large leaves to catch more light.
Term
Freshwater (water biome)
Definition
characterized by a major abiotic feature→ the speed at which water moves
- The speed of the current determines what type of organisms live in a stream or river.
Term
Tributary
Definition
each trickle, stream or river that joins a larger trickle, stream or river.
Term
Estuary
Definition
an area where fresh water from streams and rivers spills into the ocean (so the fresh and salt water mix).
Term
Wetland
Definition
an area of land where the water level is near or above the surface of the ground for most of the year. This area is plentiful in nutrients so it has many varied plants and a large capacity for photosynthesis.
Term
Swamp
Definition
type of wetland characterized by flooded trees draped with Spanish moss and vines.
Term
Marsh
Definition
a treeless wetland ecosystem where plants such as cattails and rushes grow .
Term
Littoral zone (Freshwater Zone)
Definition
area where the water meets the land
Term
Open-water zone (Freshwater Zone)
Definition
extends from the point where water meets the land across the top of the water
Term
Deep-water zone (Freshwater Zone)
Definition
part of the water where no light reaches and organisms feed on dead organic material
Term
Marine
Definition
These biomes are based in salty water and contain the largest organisms in the world. Phytoplankton are very small photosynthetic plant-like protists that float near the surface of the ocean. (Phytoplankton are producers.) Zooplankton are very small animal-like protists (protozoa) that live in the ocean and eat phytoplankton (Zooplankton are 1st level consumers.) These biomes at the poles contain ice.
Term
Intertidal zone (Marine Zone)
Definition
area where ocean meets the land.
- sea grasses, periwinkle snails & birds live here.
Term
Neritic zone (Marine Zone)
Definition
area where water becomes gradually deeper on the edge of the continental shelf
- you can find seaweeds, coral reefs, sea turtles, and dolphins living here
- Coral reefs are structures that are formed as a result of a long term build-up of coral skeletons.
Term
Oceanic zone (Marine Zone)
Definition
extends across the ocean waters, and down about 200m.
- whales, squid and animals adapted to darkness & high pressure live here.
Term
Benthic zone (Marine Zone)
Definition
the sea floor, most areas do not receive sunlight.
- worms, sea urchins and bacteria live here.
- extends from the bottom of the intertidal zone to the bottom of the deepest ocean floors.
