Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

If the paramecium was not able to contract its contractile vacuole, it would be in danger of bursting. The cell would not be able to hold too much water. This would happen faster if the paramecium was in water with a low salt concentration because there is more water and less salt, so the water would accumulate faster.
