warmer, wider, and slower

as they flow down a mountain to flatter ground, rivers generally become

the secretion of calcium carbonate by tiny marine animals

coral reefs are intricately shaped rock-like structures that are formed as a result of

barrier

long, thin island that typically runs parallel to the shore

salt marsh

marine ecosystem dominated by grasses

mangrove swamp

marine ecosystem dominated by trees with silt-like root system

benthos

mussels, worms, and barnacles

wetlands are limited to inland freshwater environments

not a characteristic of wetlands

increasing runoff

not and environmental function of wetlands

flat, poorly drained land

swamps are commonly found on

shallow, coastal waters

the majority of marine organisms are found in

the amount of sunlight available, the presence of nutrients, the temperature of the water

the types of organisms found in a pond or lake depend on

there is no sunlight

why doesn't photosynthesis occur in deep ocean water

coastal wetland

coastal land covered by salt water much of the time

estuary

ecosystem where a river empties into the ocean, mixing fresh and salt water

nekton

free swimming organisms

freshwater wetland

land periodically cover with water of extremely low salinity

microscopic

phytoplankton and zooplankton

littoral zone

region of shallow water near the shores of lakes and oceans
