biologist
A male scientist whose field is biology, that is, the study of living organisms and their developmental processes. The female form is 'die Biologin' (female biologist).
Als Biologe erforscht er das Verhalten von Vögeln in ihrem natürlichen Lebensraum.
As a biologist, he studies the behavior of birds in their natural habitat.
'Der Biologe' (the biologist) belongs to the N-declension. This means it takes the ending '-n' in all cases except the nominative singular. So it is 'den Biologen' (accusative), 'dem Biologen' (dative), and 'des Biologen' (genitive).
Ich habe den Biologen nach seiner Forschung gefragt.
I asked the biologist about his research.
The ending '-loge' refers to a male expert in a particular, usually scientific, field. It is derived from the name of the field, here 'die Biologie' (biology).
Ein Geologe ist ein Experte für Gesteine, ein Biologe für Lebewesen.
A geologist is an expert on rocks, a biologist on living organisms.
The word belongs to a family: 'die Biologie' (biology) is the field, 'der Biologe' (the biologist) is the male expert, and 'biologisch' (biological) is the related adjective.
Seine biologische Forschung ist international anerkannt.
His biological research is internationally recognized.
scientist
'der Wissenschaftler' and 'der Biologe' can both refer to a person who works scientifically. 'Der Wissenschaftler' is the general term and does not yet say which subject someone has. 'Der Biologe' is more precise: he works in the field of biology and deals with living organisms. Learners may confuse the words because a biologist can be a scientist. So the difference is general versus specific. If the subject is not important or is unknown, 'Wissenschaftler' fits. If it is about biology, 'Biologe' is more precise.
Im Wald erklärt der Biologe den Kindern, welche Pflanzen giftig sind.
In the forest, the biologist explains to the children which plants are poisonous.

The scientists are studying how a new medicine affects the body.
