A group of ecosystems that share similar biotic and abiotic conditions.

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

The day-to-day conditions in earths atmosphere.

Describes the conditions in a biome.

Net primary production

The organic matter, or biomass, that remains after cellular respiration.

Tall trees that form a dense covering.

The top layer of the rain forest.

Layer of vegetation that grows beneath the canopy.

Plants that grow on other plants instead of soil.

Trees that lose their leaves and stop photosynthesis during part of the year.

A deep, sleep-like period of dormancy during lack of resources.

Trees that produce seed-bearing cones.

A deep, sleep like state that an animal enters for most of the winter.

Underground soil that remains frozen year round.

The amount of salts dissolved in water.

The uppermost layer of an aquatic ecosystem, where there's enough sunlight for photosynthesis.

Where no sunlight penetrates, and photosynthesis cant occur. Below the photic zone.

The very bottom of a body of water.

The shallow, near-shore portion of the photic zone.

Where there are no rooted plants, farther from the shore.

Areas of land that are flooded with water at least part of the year,

Areas nearest to a rivers course that are flooded periodically.

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.
