Biologists are scientists who study living organisms and how those organisms respond to their environment. Biologists might study the human body to better determine how it works and help advance the medical field, or they might use their biology degree as a zoologist, managing animals in captivity or in the wild. Or, a person with a degree in biology might work in agriculture as a botanist or ecologist, developing new strains of food that are less susceptible to pests and disease.
There are many different types of biologists, and therefore, many different types of working environments in which biologists may find themselves. Most biologists are employed by a university, independent laboratory or the government. Depending on the type of biology a scientist focuses on, they may spend most of their time in a laboratory or in the field, collecting data, performing research and drawing conclusions.
