Trophic Levels Of Coral Reefs Sciencing A coral reef is a diverse environment that encompasses a wide ranging food web. trophic levels in a coral reef describe the feeding position of the plants and animals that make up that ecosystem. plants, which are able to create their own energy, are primary producers. herbivores, creatures that eat primary producers, make up the second level. Fig. 5 correlation between bleaching resistance and corallite area under field conditions. despite uncontrolled field conditions, corallite area (a proxy for trophic strategy) explains 43% of the variation in bleaching susceptibility among corals off the east coast of africa during the 1997 bleaching event (28).

On coral reefs, trophic ecology is fundamental to our understanding of how reefs are organized and sustained. indeed, trophic interactions underpin many of the processes that drive coral reef community struc ture and the key ecological services these ecosystems provide (brandl et al., 2019; burkepile and hay, 2006; mcleod et al., 2019). In coral reefs, the semi open nature of communities increases the difficulty in mapping food webs from source to consumer and the influence mesopredators may have on lower trophic levels. trophic cascades were mentioned in 24 percent of reviewed publications, yet there is little empirical evidence documenting cascading effects in coral reefs. 3. herbivory, predation, and trophic cascades on tropical reefs3.1. herbivory. coral reefs are biodiverse ecosystems with complex food webs (mcmahon et al., 2016).even on the relatively species poor reefs of the tropical eastern pacific, nearly 300 interspecific links exist in the subweb of corals, coral eating animals, and their higher level predators (glynn, 2004).

Introduction. tropical coral reefs are among the most biologically diverse and valuable ecosystems on earth. coral reef ecosystems provide provisioning, regulating, cultural, and supporting services such as small scale artisanal and commercial fishing, coastal protection, sand production, recreation, tourism, food, and medicines (kennedy et al. 2013; woodhead et al. 2019).
