Answer:B. Sunlight provides energy to producers
Explanation: photoautotrophs (plants) produce energy from sunlight by photosynthesis. This is the only energy production based on an external source of energy. Plants, whether alive or dead, are consumed by heterotrophs - bacteria, fungi and animals. The nutrients and energy from dead heterotrophs (and some live ones) are recycled by both autotrophs and heterotrophs.
The answer is A p is the frequency of the dominant allele. So the p squared would be the frequency of the homozygous dominant allele because homo means the same.
Good evening Aixa,
An experiment is designed so that you can observe the differences between the experimental group and the control group.
The experimental group is the group of specimens you're exposing to the experiment and the control group is a separate group of specimens that is not being exposed to the experiment, but are also being observed.
-Hope this helps!
