Answer:
<em> It explains how nature works.</em>
Explanation:
A scientific theory can be described as a descriptive explanation of the occurrence of any phenomenon taking place in the natural world. Other statements are not true because a scientific theory is explained best with the help of certain experiments and certain known facts. It might be based on results from many experiments and supported through many known facts. A scientific theory has the capacity to replicate its results when performed again and again.
There are no choices but examples of biotic factors are trees, mosses, ferns, fungi, mammals, birds, reptiles, worms, plants, and lichens.
