VERY EASY QUESTION. WILL MARK BRAINLIEST Most aquatic organisms are adapted to a narrow range of salinity. Why must aquatic organisms living in coastal areas be adapted to survive in both low and high salinity?

During high tide, organisms are exposed to air, lowering salinity.

During low tide, the ocean water becomes concentrated, increasing salinity.

Ocean currents bring in deep-ocean water with high salinity concentrations.

Temperature fluctuations can cause changes in the salinity levels of the water.

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
