Chemistry is the study of matter, analysing its structure, properties and behaviour to see what happens when they change in chemical reaction.However Biology is the signs of life and living organism. So this is basically the study of life and living organisms.

Biology is the study of living organisms and their interactions with the environment. It encompasses a wide range of topics, from the smallest unit of life, the cell, to the largest ecosystems on Earth. Biology seeks to understand the diversity of life forms, their functions, and the processes that sustain life. Chemistry is the study of matter and the interactions between different forms of matter. It encompasses a wide range of topics, from the structure of atoms and molecules to chemical reactions and the properties of substances. Chemistry seeks to understand the composition and behavior of matter, and how these properties affect the natural world and our daily lives.

As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. On the other hand Chemistry is the study of matter's constituents, such as atoms, molecules, and ions, as well as their characteristics, structure, behaviour, and interactions. Finally Physics, or the study of matter, energy, and the interactions between them, helps us to understand the laws and rules that govern the physical world.
