Which bugs (orange or green) were eaten more when there was a low level of pollution (background green)?
Which bugs (orange or green) were eaten more when there was a high level of pollution (background orange)?
What factor determined the survival of the bug? Why?
If the pollution level is high for an extended period of time, does this affect the survival of the green bugs? Yes or No.
Would they increase or decrease over time?
If the pollution level is low for an extended period of time, does this affect the survival of the orange bugs? Yes or No.
Would they increase or decrease?
In natural selection, the organisms that are best suited to survive in an environment have the most babies and grow in numbers, while organisms that aren't as well suited to the environment shrink and disappear. True or False.
Do you think this process occurs over a short period of time or a long period of time?
