Considering the following statements;
A. It can exist without a constant source of energy input
B. It must contain consumers but can exist without producers.
C. It involves interactions between biotic and abiotic factors.
D. It can exist on land, but it cannot exist in lakes, rivers, or oceans.
The correct statement is C. that an ecosystem involves interactions between biotic and abiotic factors.
Biotic factors are the living things in an ecosytem, they include plants, animals, bacteria, fungi and others.

The two types of factors are crucial for an ecosystem to exist and thrive.
I believe that the cells will decrease in size as water flows out of it. The red blood cell is hypotonic to the the solution while the solution is hypertonic, therefore, the blood cells losses water osmotically and decrease in size. Water moves from inside the cell to the outside by osmosis. The end result is the shrinking of the red blood cells.
