Trophic levels (TLs) for individual groups ranged from 1.0 to 4.22. Ecotrophic efficiency for most of the small pelagic fishes was found to be greater than 0.7. For hilsa it was 0.853, indicating high exploitation of this fish within the system. The nBoB was estimated to be a low ...
Both a high number of species and abundance in multiple trophic levels are required for ecosystems to continue to provide the services humans require of them. Numerous experiments have shown that the loss of biodiversity within single trophic groups — g

Under climate change, model ensembles suggest that declines in phytoplankton biomass amplify into greater reductions at higher trophic levels, with serious implications for fisheries and carbon storage. However, the extent and mechanisms of this trophic

It is considered more efficient to be an organism at a lower tropic level rather than a higher one because you would have more energy than the ones above you. At a higher tropic level, your energy is almost nothing compared to the lower levels because you've lost 90% of the energy the...
