biologischen

Biologischen is the declined form of the German adjective biologisch, meaning biological. It is used to describe things related to life or living organisms and is inflected to agreement with the noun it modifies in gender, number, and case. The ending -en appears in many common cases, including masculine and neuter singular in the genitive or dative and in all plural forms, as well as with certain singular masculine nouns when the article is present.

Examples of common forms:

- Masculine singular with definite article: der biologische Prozess; den biologischen Prozess; dem biologischen Prozess; des biologischen Prozesses.

- Neuter singular with definite article: das biologische Phänomen; des biologischen Phänomens; dem biologischen Phänomen.

- Plural with definite article: die biologischen Prozesse; den biologischen Prozessen; der biologischen Prozesse.

- Without an article (attributive use): Biologische Prozesse sind Gegenstand der Forschung; biologischen Kontexten.

Usage notes:

Biologischen is typically used when the noun is specified by a determiner (der, die, das, ein, mein, etc.) or when it appears in a declined plural form. The form also appears in phrases indicating location or manner, such as in biologischen Prozessen oder in biologischen Kontexten. By contrast, the basic positive form biologisch is used as a plain descriptor or as an adverb in phrases like biologisch erklären (to explain biologically).

Etymology and scope:

The word derives from Biology (Biologie) and the Greek roots bios (life) and logos (study). In German, biologisch can describe natural-science concepts, medical contexts, agricultural practices (for example, biologische Landwirtschaft in everyday language), and discussions of life-related phenomena. The term forms part of numerous compound expressions and is widely used across science, industry, and media.
