Both a whale giving birth to a calf and bacteria replicating through cloning are examples of biological processes that require energy, although the processes and energy requirements differ significantly between the two.

1. Whale Giving Birth: The process of gestation and giving birth requires considerable energy. The mother whale must invest energy in nourishing the developing calf, which involves metabolic processes that sustain both her own body and the growth of the calf. This energy is derived from the whale's diet and stored reserves.

2. Bacterial Replication: Bacteria replicate through binary fission, a form of asexual reproduction. While this process is much simpler than mammalian reproduction, it still requires energy. Bacteria need energy to synthesize the cellular components necessary for cell division, replicate their DNA, and ultimately divide into two separate cells. This energy is obtained from nutrients in their environment, which are converted into usable forms through metabolic processes.

In summary, both processes illustrate the need for energy in biological systems, but they do so at different scales and complexities.
