Answer:
3. Fewer deer and more competition for panthers.
Explanation:
The answer that is most probable in this situation is that the number of panthers has decreased, causing there to be more deer for the leopards to prey on. Before this occurred, the leopards and panthers probably competed to prey on deer. If there are significantly less panthers around, more leopards will be able to prey on the deer in the ecosystem.This can also decrease the deer population and make more competition for the panthers, as their numbers would be small compared to those of the leopards.
However, in Earths First Billion years and over the past 4.5 billion years, the main source of water was from comets. We know that comets consist chiefly of chemical compounds that are either gases or liquids at earth-surface conditions: methane is one common component of comets and water is another.
