Definition
receive relatively large inputs sediments, organic material, and inorganic nutrients from their surroundings allowing them to support Dan’s plant communities.
Term
Aphotic zone
Definition
where nearly all the energy needed to support life is extracted from the excrement and bodies of organisms that sink or swim into this deep region.
Term
Biodiversity
Definition
refers to the total number of species within an ecosystem and the resulting complexity of interactions among them.

littoral waters are also home too small, unattached organisms collectively called…
Term
Profundal zone
Definition
where light is too scarce to support photosynthesis.
Term
Rain shadow
Definition
he cool, dry hair is warm again as it travels down the far side of the mountain and absorbs water from the land creating a local dry area called a rain shadow.
