The populations of parrotfish and long-spined sea urchins have changed primarily due to overfishing, habitat loss, and the impacts of climate change. Parrotfish are often targeted for their meat, leading to declines in their numbers, while long-spined sea urchins faced massive die-offs due to disease and environmental stressors. Additionally, the decline of coral reefs, which provide essential habitats, has further disrupted these species' populations. The changes in their populations can significantly affect coral reef ecosystems, as both play crucial roles in maintaining coral health and structure.

I really don't know
new species form.
In biological terms it is the change in certain characteristics of populations of organisms of the same species
Crissy Briana Neally is truly awesome(: *yeeeaaah!
On the local scale tornadoes can kill large numbers of animals.
Parrotfish have specialized beak-like teeth that allow them to scrape algae off coral reefs. They also have a mucous cocoon that they excrete to protect themselves from parasites while sleeping at night. Some parrotfish can change color to blend in with their surroundings or to communicate with other fish.

Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.

Yes. While it's running, it can damage habitats and it can drop the populations by ALOT!! It can change the species type, because alot of species are endangered, and some hurricanes (if they hit in the right spot) can actually make the species go endangered. Hope this helped!!
