Question Answer
contain standing water lentic
water is constantly moving lotic
very low in nutrients, populations of plankton and algae are very low oligotrophic
have greater concentrations of nutrients, removes a growth limiting factor for algae and plankton eutrophic
narrow channels of water, moves rapidly across rocks and down waterfalls stream
generally cold, rich in oxygen, and low in nutrients source zone
streams widen, become deeper and are warmed by the sun transition zone
low-lying areas experience wide, slow-moving rivers that occasionally flood and deposit material flood plain zone
fresh water mixes with saltwater, forming brackish water mouth
do not have trees marsh
do have trees swamp
wetlands characterized by plants that produce acidic secretion, slows down action of decomposers bog

areas of land that are fully saturated with water at least part of the year coastal wetlands
gravitational pull of the moon and sun causes tides to rise and fall – submerged during high tide and exposed during low tide intertidal zone
network of leftover skeletons creating crevices and ledges.. coral reef
sufficient sunlight for photosynthesis 200m in depth photic zone
little to no sunlight 200m-1500m in depth; also known as the bathyal zone aphotic zone
no sunlight (ocean floor) 1500m-10,000m in depth; also known as the abyssal zone benthic zone
