How does zoology relate to science??

Answer 1

In a general sense, science is the study of the natural world around us (chemistry, biology, physics, etc.).
From the Encyclopaedia Britannica:
Zoology is a "branch of biology concerned with the members of the animal kingdom and with animal life in general. It embraces all conceivable forms of study, not only of the components of the animal body and the vital processes that sustain it but also of the relations of individual animals or animal groups with one another and the environment."
Hope this helps
