APES Unit 1 Flashcards

(1.2) Temperate Forests have nutrient..

..rich because lots of dead organic matter and leaves get decomposed thanks to warm temperature and high moisture.

(1.2) Boreal forests have nutrient..

..poor soil because of low temperatures and low decomposition rates of dead organic matter.

(1.2) Tropical rainforests have nutrient..

..poor soil due to high competition from so many different plant species.

(1.2) Tundra and Boreal biomes are found..

..above 60 degrees North latitude.

(1.2) Temperate biomes are found..

..between the 30-60 degrees latitude.

(1.2) Tropical biomes are found..

..along the equator.

(1.2) Biomes shift because..

..of the tundra permafrost soil melting leading to lower latitudes to become too warm for Aspen and Spruce.

What do freshwater biomes include?

They include streams, rivers, ponds, and lakes.

What is considered a marine biome?

Oceans, coral reefs, marshland, estuaries.

The biggest suppliers of Earth’s oxygen

Algae in marine biomes.

(1.3) Salinity is..

..how much salt there is in a body of water which determines how drinkable it is.

(1.3) Littoral

Shallow water of a lake with emergent Plants.

(1.3) Limnetic

Where light can reach and photosynthesize in a lake.

No rooted plants and only phytoplankton are found in which part of a lake?

Limnetic zone

(1.3) Profundal zone

Too deep for sunlight meaning no photosynthesis

What level of a lake contains a murky bottom where bugs and nutrient rich sediments reside?

Benthic Zone

Stores excess water during storms, recharges ground water

Wetland (1.3)

Estuaries along coast in temperate climates are..

Salt Marshes

The relationship between coral reefs and algae

Mutualism

How does coral maintain mutualistic relationships between surrounding marine plants?

Coral takes CO2 out of the ocean to create calcium carbonate to provide CO2 to algae living in Reefs.
