Biology is an interdisciplinary study, which means that it relies on and depends on many other studies. You cannot always study biology without paying attention to other sciences as well, because they are so interconnected. For example, history and biology are connected - in biology, you study evolution, which is how beings evolved through history. Also, physics is important to biology - various chemical process that take place in both humans and other living beings is what both chemistry and biology study. Geography and biology are also closely-knit, given that geography has to do with the Earth and its ground on which plants and other living beings exist.
