biotickém

Biotickým is the instrumental singular form of the Czech adjective biotický, which means biotic or pertaining to living organisms. It is used in biological and ecological contexts to describe factors, processes, or interactions associated with the living components of an ecosystem. The word biotický itself derives from biota and life-related roots, and follows standard Czech adjectival declension.

In ecological usage, biotic factors are the living elements of an environment. They include producers such as plants and algae, consumers such as herbivores and predators, decomposers like bacteria and fungi, and the interactions among them—predation, competition, symbiosis, parasitism, and disease. The instrumental form biotickým often appears in phrases describing how organisms are affected, for example biotickým tlakem (biotic pressure) or biotickým faktorem (a biotic factor).

Biotic factors interact with abiotic factors to shape ecosystems and population dynamics. Biotic interactions influence species diversity, community structure, and energy flow through food webs, while abiotic conditions such as climate, soil, and moisture provide the environmental context. In scientific literature, distinguishing biotic from abiotic influences helps researchers study ecological niches, species distributions, and ecosystem resilience. The term is widely used across biology, ecology, agriculture, and environmental science in Czech-language texts.
