What gas do a rabbit and flower need for aerobic respiration?

Both a rabbit and a flower need oxygen for aerobic respiration.

Here's why:

* Aerobic respiration is the process of breaking down glucose (sugar) in the presence of oxygen to release energy.

* Oxygen is the final electron acceptor in this process, allowing for the efficient production of ATP (the energy currency of cells).

While both rabbits and flowers use oxygen for respiration, they obtain it in different ways:

* Rabbits breathe air through their lungs.

* Flowers obtain oxygen through tiny pores on their leaves and stems called stomata.
