life sciences
Study of organisms
Life sciences are the branches of science that study living organisms—biology, zoology, botany, ecology, genetics, and related fields.
The term distinguishes these disciplines from physical sciences like physics and chemistry, though the boundaries blur in fields like biochemistry.
She pursued a career in the life sciences after college.
