Probably some of them (example:crocodile). The crocodile is a modern species of what use to be a prehistoric creature. The species would adapt based on the environment due to natural selection.
just to expand on that the croc has remained unchanged since the time of the dinosaurs,
they did not need to adapt why would they? what would they have to adapt to? what environment change are you talking about? The people were there and that was it.
If an animal were to adapt to a salt marsh, they would have to adapt to the climate. It varies sometimes but mostly they would have to adapt to the water source. In a salt marsh, they have brachish water, which is a mixture of salt water and fresh water, and it usually leads out into another river or stream somewhere close by, but they would have to adapt to the water, which only some animals can.
animals adapt to differents biomes because
Animals change and adapt through evolution by natural selection.
Animals adapt by changing little features to adapt.
Animals must adapt to their environment because if they diddent adapt, they would not be fit to survive where they are. EDIT:
Evolution. Over hundreds of years animals will change to adapt to there surroundings.
they adapt by mutations in their genes when they have newborns.
by growing and adapting to the harsh weather an example would be their thick coats
This is not a question who knows what you are talking about
Animals adapt to their environment in order to survive and thrive. This adaptation helps them find food, avoid predators, and reproduce successfully. Over time, those individuals with advantageous traits are more likely to pass on their genes, leading to better adaptation to their surroundings.
It could possibly die, animals must be able to adapt to the habitat in which they live in. If the do not adapt, the could die.
