In order for the brown organisms to survive up in the mountains, what would need to happen?

• They need to adapt and be faster at getting away

• There would need to be a mutation in their gene that causes their color to change gray.

• They would need to migrate and find an environment that helps them blend in.

• All of these options would benefit the brown organisms to survive longer.

Why is the continuous cycle of adaptation and survival of the fittest essential for the diversity of life on Earth?

• It ensures that only the strongest individuals survive

• It leads to the extinction of weaker species

• It allows for the development of new traits and species

• It prevents any changes in the environment
