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 like "sunny and humid" or "cold and snowy".

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.

The tallest trees pop through the canopy and make up the top layer of the rain forest.

Are plants that grow on other plants instead of in soil

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

When conditions dry, some animals enter deep. sleep like period of dormancy.

Trees that produce seed-bearing cones

Is a deep, sleeplike state that an animal enters for most of winter.

Because of the cold climate, underground soil remains frozen year-round

Measures the amount of salts dissolved in water

The uppermost layer of an aquatic ecosystem, where there is enough sunlight for photosynthesis

Where no sunlight penetrates and photosynthesis cannot occur

The very bottom of a body of water

The shallow near shore portion of the photic zone

Is farther from the shore, where there are no rooted plants

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

Areas nearest a river's course that are flooded periodically

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 converge, or come together
