We need to see an ecosystem that goes with the rat to answer this question.
Cell divison is necessary to replace cells that are worn and aging. Cells do not have an indefinite life span. Fo example, the life span of a red blood cell is about 120 days.
The
infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the
toucan's muscle cells would not be able to obtain as much chemical energy as
they normally do. This chemical energy will be converted into mechanical energy
or heat flow, which the toucan uses to fly.
Therefore, the lower amount
of mechanical energy and heat flow from the muscle contractions, it would
result into a reduced amount of kinetic energy of motion when the toucan is
flying.
I'm fairly sure it would be windward and leeward. So C
