Question

Give answer, what happens when organisms survive accidentally?

Answer 1

Answer: Sometimes for a species, the environmental conditions change so drastically that their survival becomes difficult. For example, if the temperature of water increases suddenly, most of the bacteria living in that water would die. Only few variants resistant to heat would be able to survive.

Answer 2

All organisms have adaptations that help them survive and thrive. ... Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation. For example, imagine a bird species.
