A biologist is a scientist who studies living things and how they act and react to the environments in which they live. Numerous types of biologists exist. These include research biologists, health care biologists, environmental biologists and biology educators.
Research biologists study different groups of living organisms around the world. These types of biologists use state-of-the-art research techniques and tools to examine species such as micro-organisms, mammals, reptiles and amphibians in their natural habitats. Therefore, research biologists generally perform their work in exotic locations across the globe.
Health care biologists include physicians, veterinarians, nurses and dentists. These types of biologists prevent the spread of infectious and deadly diseases and formulate ways to enhance the health and well-being of their patients.
Environmental biologists seek out new ways to preserve the natural environments of different types of organisms. For example, zoo biologists study animals in captivity and design new preservation methods to help certain species live fuller, longer lives in their natural habitats. Conservation and management biologists further the work of these types of biologists by working with state and local authorities to develop laws and practices that protect the lives of groups of animals that cohabitate with humans or live near neighborhoods or urban developments.
Biology educators teach students and up-and-coming biologists basic and advanced biological sciences in classroom, laboratory and field settings.Learn More

A scientist who studies plants is called a botanist. Also called plant biologists, botanists study diverse plant life ranging from small microorganisms to giant trees. As experts in the field of botany, botanists are well-versed in the identification and classification of plant life, the biochemical functions and processes of plants and the various plant diseases and cures.Full Answer >
All known living things are composed of one or more cells, and they contain carbon compounds and water. All known life reproduces independently and passes down heritable genetic information to offspring in the form of nucleic acids.Full Answer >
The characteristics that all living things share are cells, growth, reproduction, adaptation, homeostasis, use of energy and response to the environment. Using these characteristics, it is easy to determine if something is living, dead or non-living.Full Answer >
