How do animals adapt to their environment
Surface area
Insulation
Body fat
Water storage
How do microbes adapt to their environment
E.g extremophiles
Arctic,volcanic vents
•very dry environment
•severe chemical environments
How does evolution occur by natural selection
Gradually change over time to become more adapted to their environment
•genes enabling individuals to survive are then passed on to the next generation
Individuals with characteristics most suited to their environment are more likely to survive and reproduce.
What happens to the genes that allow these individuals to be successful?
passed on to offspring
what is an extremophile
survive in extreme environments
(very dry, severe chemical)
volcanic vents
deep under oceans
what happens if a species is poorly adapted to its environment?
it will not survive and eventually become extinct
