The plants use the sun as their energy, using photosynthesis.
The insect and animals get their energy from the food they eat.
And bacteria get their energy by decomposing dead organisms.

You might have to do the research on what each animal eats if you need specific answers.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
