Simple question with a complex answer. Biology covers many areas of study, but at their core, biologists study living organisms, or aspects thereof. Ecologists study organisms in relation to their environment. Paleontologists study the traces of organisms that once existed - a sub-discipline of biology, etc. etc..

A biologist may study life at many levels, and often they specialize on one of those levels. Here is a brief description of those levels from macro to micro:

  • Community ecologists study groups of organisms living in a "community", and their study may include aspects of the physical environment in which they live (geological, meteorological, hydrological or chemical).
  • Organismal biologists usually study one type of life form, and this can range from their morphology (design), physiology (how they work), behavior, their overall ecology (relationship to their environment), etc.. some study taxonomy/systematics, or how organisms are classified into groups or kind.
  • Cellular biologist study living things at the cellular level. A sub-discipline is biochemistry - the study of chemical reactions that take place in living organisms.

So, there is a very broad range of studies within biology. Myself, I am a general ecologist studying desert organisms in the Mojave Desert, and my specialty is in pollination ecology (the study of how vascular plants accomplish reproduction through pollination, either by the services of animal pollinators or by other means), and how those systems have evolved to their current state.
