Ecological diseases, also known as wildlife diseases, can significantly impact various wildlife populations. For example, White-nose Syndrome in bats and Chytridiomycosis in frogs are both ecological diseases that have caused significant declines in these populations.

The other two statements are not entirely accurate. Human activities can often influence the spread and impact of ecological diseases. For instance, habitat destruction can make wildlife more susceptible to disease. Additionally, some wildlife diseases can also affect humans, either directly or indirectly. For example, Lyme disease is an ecological disease that can be transmitted to humans by ticks.
