Biologists wear many hats. They may work in the field, in a lab or with computers. Their careers can be short-term or long-term and they are often self-employed.

Biologists study all forms of life, from plants and animals to microbes. They also study the relationships between organisms and their environments. For example, a biologist might study how animals adapt to changes in their environment or how plants survive in harsh conditions.

A biologist might work in a lab or field setting, using tools such as microscopes, telescopes and binoculars. Some biologists work at universities and other research institutions; others work for private companies that develop new drugs or pesticides. Biologists also teach at higher education institutions (such as colleges and universities) and may assist doctors by providing advice on disease prevention and treatment.
