Biology is the study of life
and living organisms. Biologists study the structure of living things
and how they grow. They study how they evolve
and what they do in the environment. Biologists also study where they live and how they are related to other living things
. Biologists study life from the tiniest sizes of cells to the scale of ecosystems
Because all things are made of chemicals, a biologist must understand chemistry to be able to understand life. Similarly, because life can effect other parts of Earth (like the atmosphere, water, and Earth's surface), many geologists must understand biology. Biogeochemists specialize in the study of how life, chemistry, and the Earth effect each other.
