Some groups may be food limited, given the strong seasonality of phytoplankton growth and production, whereas others can be limited by strong predation. For example, krill can accumulate to incredibly high concentrations (called superswarms; which can reach mean concentrations of 100 krill m− 3 ...
OM stored in the jellyfish biomass is present in the form of dissolved organic matter (DOM), which is rapidly leaching into the ambient seawater being readily and exclusively accessible to marine microbes propelling biogeochemical cycles at the base of the oceanic food web [20,26,27]. This imp...
Step-by-Step Solution:1. Understanding Food Chains: In any food chain, energy flows from one trophic level to another. The primary source of energy in a typical food chain is usually autotrophs, such as plants,
In graziing food chains, green plants (producers) constitute the first trophic level. In detritus food chain, decomposers or detritivores constitute the first trophic level. They feed on detritus (dead decaying organic matter).
