Explanation:
The Chesapeake Bay is an example of an estuary that is located in the United States. It is a source of edible marine creatures such as oysters, crabs, prawns e.t.c
Over the years, non - sustainable harvesting of oysters by farmers have been happening at Chesapeake bay, resulting in a reduction in the amount of oysters present.
Plants absorb the water from the soil ( through their roots) and then release it back into the atmosphere by transpiration (evaporation from the leaves)
The group in an experiment that all the conditions stay the same is the control group.
