Natural Selection. Survival of the fittest. The organisms with the best traits are able to survive and reproduce.
small changes add up over time
Only the best-adapted organism will survive.
natural selection
organism best adapted to their environment survive- apex
If the species environment is not the way the species needs it to survive then the species will become extinct. for example, if doesn't have any trees, then it cant survive.
Koalas can only survive in specific types of bushland environments which contain their preferred eucalyptus species. They cannot survive in the tundra, deserts, grasslands or rainforest, as none of these environments support their preferred eucalyptus.
natural selection
no organisms adapt to the environment to help them survive
The scientific name for xerophiles is xerophilic organisms. Xerophiles are organisms that can thrive in very dry environments with low water availability. They have adapted mechanisms to survive in these harsh conditions, such as producing protective proteins or accumulating solutes to prevent dehydration.
