Reproduction does not help a species to survive, it allows for a species to survive by replacing the ageing population. Without reproduction a species would cease to exist within 1 generation. By reproducing, the species adds to it's population, which helps the species to survive for a longer period of time, because they will not be killed off as easy and will not go extinct:)
There are a number of species of rat that live in deserts around the world. It would be a big help if you named a particular species.
It causes diversity and variation amongst a population
The animals with the abilities that will help them to survive better than those without the same abilities will likely survive longer and will not be killed by predators. Those animals will live on and give their children the same abilities to survive, helping the species to adapt to a hostile environment.
increase in frequency
their skin because like bears in Antarctica survived because of the fur the have as skin which keeps it warm
Species that lack a diverse gene pool are less able to adapt to changes in the environment and are less able to survive diseases.
It allows them to travel to areas of greatest resources to survive.
no organisms adapt to the environment to help them survive
Behaviors such as hunting for food, seeking shelter, avoiding predators, and communicating with others of its species all help animals survive in their environment.
The gills help it breathe.
