The ending '-logie' in German often refers to a science or field of study, as in 'Biologie' (biology) or 'Psychologie' (psychology). 'Ökologie' (ecology) is literally the study of the 'household' (Greek 'oikos') of nature.
Die Soziologie untersucht das menschliche Zusammenleben.
Sociology studies human social life.
The related adjective is 'ökologisch' (ecological). It describes everything connected with the environment, sustainability, or the science of ecology.
Viele Verbraucher achten auf einen ökologischen Lebensstil.
Many consumers pay attention to an ecological lifestyle.
When 'Ökologie' (ecology) means the science, it is often used in academic contexts. Typical collocations are 'Ökologie studieren' (to study ecology), 'Institut für Ökologie' (institute of ecology), or 'Professor für Ökologie' (professor of ecology).
Sie hat ihren Master in Ökologie an der Universität Freiburg gemacht.

When it is about the balance in a habitat, the specific place is often mentioned, e.g. 'des Sees' (of the lake), 'des Waldes' (of the forest). Common verbs in this context are 'stören' (to disturb/disrupt), 'zerstören' (to destroy), 'schützen' (to protect), or 'wiederherstellen' (to restore).
Die Trockenheit stört die empfindliche Ökologie des Sumpfgebietes.

biology
'Biologie' and 'Ökologie' both have to do with living organisms. 'Biologie' looks at living organisms in general, for example their bodies, their development, or their life processes. 'Ökologie' focuses especially on how living organisms live together with their environment, such as climate, water, plants, animals, and humans. Learners can confuse the words because both appear in the natural sciences. 'Biologie' is the larger field. 'Ökologie' fits when the relationships within a habitat are important.
