Trophic effect
WebTritrophic interactions in plant defense against herbivory describe the ecological impacts of three trophic levels on each other: the plant, the herbivore, and its natural enemies.They may also be called multitrophic interactions when further trophic levels, such as soil microbes, endophytes, or hyperparasitoids (higher-order predators) are considered. ...

WebCCK may have important trophic effects on normal and neoplastic tissues. CCK delays gastric emptying in several species, an effect that may be vagally mediated. Endogenous CCK may also play a role in gastric acid secretion and in the control of lower esophageal sphincter pressure. WebAn organism may not always occupy the same trophic level, depending on the food web. Assigning organisms to trophic levels isn't always clear-cut. For instance, humans are omnivores, meaning they can eat both plants and animals. So they may be considered both primary and secondary (or even higher!) consumers.
