Question 2:
<span><u>slow, steady evolution of a small isolated population</u></span><span>
This evolutionary theory suggests that a species slowly and continuously evolved over a long period of time. This selection and variation happens more gradually. It is hard to notice over a short period of time. The change is slow, constant and consistent. In punctuated equilibrium, the changes come in spurts. There are periods wherein a huge change occurs and there are also periods with very little change. The mutation is at random. Genetic drift is the change in the frequency of a gene variant due to a random sampling of organisms. </span>
If there were no decomposers, the earth would be littered with dead animals and waste that urgently needed to be broken down. Decomposers help give the soil nutrients and keep the ground clean.
Hope this helps! :)
