Trophic position of hydra oligactis

WebTrophic position is the weighted mean path length (i.e. the number of trophic transitions) taken by energy from primary producers to consumers, and thus represents a continuous measure of an individual's function in the flow of energy through a food web (Levine, 1980 ). Specifically, the trophic position of a consumer can be calculated as: (1) WebThus, the study of inter-species interactions in Hydra and other cnidarians may be a paradigmatic example of a complex community that influences the host’s health and development.
