Explanation:

The main idea is the central point that the author is trying to communicate in a paragraph or text, although we usually find the main idea at the beginning of the paragraph, but we may also find the main idea in the middle of the paragraph after the author introduces the main idea, and then gives supportive information, or at the end of the paragraph with supportive information presented before the main idea.

In this case, the author introduced us to what metamorphosis is about, and how students and scientists study it, but how change is in the every day life, not only on scientific studies.

To define the main idea we need to ask what the topic of the paragraph is, and what the author is trying to express through the information presented, as well as the purpose of the paragraph.
