Biotickými

Biotickými is the instrumental plural form of the Czech adjective biotický, meaning biotic or related to living organisms. It is used in biological and ecological contexts to describe living components of an environment or to denote actions performed by living things. The term derives from the Greek bios meaning life, combined with the Czech suffix -tický, which forms adjectives that agree with nouns in gender, number, and case.

In usage, biotickými modifies masculine plural nouns in the instrumental case. For example: biotickými faktory (by biotic factors) and biotickými podmínkami (with biotic conditions). The corresponding nominative form is biotické faktory. Like other Czech adjectives, biotický declines in all cases and numbers to yield forms such as biotický, biotického, biotickému, biotickou, biotickým, biotickými, depending on the syntactic role.

In ecological discourse, biotické faktory refer to living elements such as producers, herbivores, predators, and decomposers, and their interactions, contrasting with abiotické (abiotic) factors such as climate, soil, and moisture. The distinction between biotické and abiotické factors is central to studies of ecosystems, biodiversity, and environmental management.
