Alright kiddo, so have you ever drawn a picture and written your name at the bottom so people know you made it? That's kinda like what a bibliography is, but instead of a picture, it's about books and articles written by different people about a certain topic.
Now, biology is all about living things, like plants and animals, and how they work. So, a bibliography of biology is a list of all the books and articles that talk about different aspects of biology, like how plants grow, or how your heart beats, or how animals adapt to their environment.
When someone writes a book or article about biology, they usually include a list at the end that shows where they got their information from. That's called a "citation." A bibliography is just a big list of all the citations from different books and articles that talk about biology. It's like a big list of names, just like your picture has your name at the bottom.
By looking at a bibliography of biology, scientists and researchers can find all the different sources of information about a certain topic. This helps them learn more about biology and find new things to study and discover.
Does that help you understand what a bibliography of biology is, little buddy?
