A biome is a group of ecosystems that share similar abiotic and biotic conditions

describes the average conditions, including temperature and precipitation over long periods in a given area

the day to day conditions in Earth´s atmosphere

to describe the conditions in a biome

Net primary production

is the organic matter, or biomass that remains after cellular respiration

tall trees form a dense covering called canopy that towers 50 to 80 meters above the ground

The tallest trees pop through the canopy and make up the top layer known as the emergent layer

The canopy keeps the forest dark and damp, shorter trees and plants make up the understory

are plants that grow on other plants instead of soil

trees lose their leaves and stop photosynthesis during part of the year

When conditions are dry some animals enter a deep sleeplike period of dormancy called estivation

trees, trees that produce seed-bearing cones

is a deep sleeplike state that an animal enters for most of the winter

Because of the cold climate underground soil remains frozen year-round, and is called permafrost

salinity measures the amount of salts discovered in water

The uppermost layer of an aquatic ecosystem, where there is enough sunlight for photosynthesis is called the photic zone

The very bottom of a body of water is called the benthic zone

The shallow near-shore-portion of the photic zone is named the littoral zone here the water is shallow enough that aquatic plants grow from mud and reach above the water´s surface

The Limnetic zone is farther from the shore where there are no rooted plants

Wetlands are areas of land that are flooded with water at least part of the year

Areas nearest at a river´s course that are flooded periodically are said to be within the rivers flood plain

Estuaries are bodies of water, partly enclosed by land, that occur where fresh water from land drainage meets the water of an ocean or inland sea

The vertical flow of cold, nutrient-rich water toward the surface, occurs where horizontal currents diverge or flow away from one another

Below the photic zone is the aphotic zone where no sunlight penetrates and photosynthesis cannot occur

Term	Definition
Biome	A biome is a group of ecosystems that share similar abiotic and biotic conditions
Climate	describes the average conditions, including temperature and precipitation over long periods in a given area
Wheather	the day to day conditions in Earth´s atmosphere
Climatograph	to describe the conditions in a biome
Net primary production	is the organic matter, or biomass that remains after cellular respiration
Canopy	tall trees form a dense covering called canopy that towers 50 to 80 meters above the ground
Emergent layer	The tallest trees pop through the canopy and make up the top layer known as the emergent layer
Understory	The canopy keeps the forest dark and damp, shorter trees and plants make up the understory
Epiphyte	are plants that grow on other plants instead of soil
Deciduous	trees lose their leaves and stop photosynthesis during part of the year
Estivation	When conditions are dry some animals enter a deep sleeplike period of dormancy called estivation
Coniferous	trees, trees that produce seed-bearing cones
Hibernation	is a deep sleeplike state that an animal enters for most of the winter
Permafrost	Because of the cold climate underground soil remains frozen year-round, and is called permafrost
Salinity	salinity measures the amount of salts discovered in water
photic zone	The uppermost layer of an aquatic ecosystem, where there is enough sunlight for photosynthesis is called the photic zone
Benthic zone	The very bottom of a body of water is called the benthic zone
Littoral zone	The shallow near-shore-portion of the photic zone is named the littoral zone here the water is shallow enough that aquatic plants grow from mud and reach above the water´s surface
Limnetic zone	The Limnetic zone is farther from the shore where there are no rooted plants
wetland	Wetlands are areas of land that are flooded with water at least part of the year
Flood plain	Areas nearest at a river´s course that are flooded periodically are said to be within the rivers flood plain
Estuary	Estuaries are bodies of water, partly enclosed by land, that occur where fresh water from land drainage meets the water of an ocean or inland sea
Upwelling	The vertical flow of cold, nutrient-rich water toward the surface, occurs where horizontal currents diverge or flow away from one another
aphotic zone	Below the photic zone is the aphotic zone where no sunlight penetrates and photosynthesis cannot occur
