Question

1. what would happen if all individuals in a species were sterile (not able to have babies)?

Explanation:

Reproduction is essential for a species' survival. If all individuals in a species are sterile, there will be no new offspring. Over time, as the existing individuals die (due to natural lifespan, predation, disease, etc.), the population of the species will gradually decrease until there are no remaining individuals, leading to the extinction of that species. This is because without the ability to reproduce, the species cannot replace or add to its population, and the existing members will eventually be lost.

Answer:

If all individuals in a species were sterile (unable to reproduce), the species would become extinct. As existing individuals die (from natural causes, predation, disease, etc.) and no new offspring are produced to replace them, the population would gradually decline until there are no members of the species left.
