Some biological technicians work for private companies or nonprofit organizations, while others work for government agencies or in college or university settings. The median pay for biological technicians is just over $46,000 per year.

Extension Agent

Working as an extension agent is a good career option for biology degree holders who are interested in and knowledgeable about agriculture. They work for land-grant universities, but most don't actually work on the campus of the university with which their position is associated. Instead, they are assigned to the extension office in a specific county within the state where the university is based. They function as local experts on agriculture topics, including things like native plants, flower or vegetable gardening, agribusiness, livestock, and more. They teach workshops, plan community events, and work individually with people who have agriculture-related questions. The average pay for extension agents is around $50,000 per year.

Food Science Technician

Whether foresters work for private businesses or government agencies, conservation and restoration are integral to their work. The median pay for foresters is around $64,000 per year.


A horticulturist works with the processes of plant life that include plant growth and production. Most horticulture jobs that are available to people with a B.S. degree involve various aspects of working with plants, such as landscaping or nursery plant production or sales. Many horticulturists operate their own nurseries, greenhouses, or landscaping businesses. Some operate market gardens or flower farms or provide education or coaching services to consumers who want to learn more about growing plants. There are opportunities for horticulturists to work in research, but those types of jobs generally require a graduate degree. The average pay for horticulturists is around $40,000 per year.

Marine Biologist

A marine biologist studies and researches the ecosystems, biology, and interaction of animals and plants in aquatic environments, such as oceans, coastal lands, wetlands, and marshes. Marine biologists with bachelor's degrees typically conduct field research and do lab work. Duties often involve observing marine life, tagging and releasing marine animals, collecting samples of water or aquatic plants, analyzing data, and contributing to lab reports. They may be employed by a wide variety of organizations, such as universities, governments agencies, nonprofit organizations, or private corporations. The average pay for marine biologists is around $40,000 per year.

Medical Photographer

If you're a biology major who also has photography skills, you may enjoy working as a medical photographer. This is one of the few science-related jobs in the medical field that doesn't require an advanced degree or a specialized license. Medical photographers are responsible for using a camera to record medical procedures or to capture images of human anatomy for the purpose of visually recording various stages of injuries or illnesses. Their work may be used for research, diagnostic, or legal purposes, and may also be used in scientific publications and educational videos. The average pay for medical photographers is around $45,000 per year.

Park Ranger

If you like the idea of showcasing public lands to visitors, you'll love putting your biology degree to work as a park ranger. Some park rangers spend most of their time developing and/or conducting educational programs designed to inform and entertain park visitors.
