Marine zooplankton proportion

The impact of marine food is directly proportional to the rate of consuming each level of marine food chain. For example, the phytoplanktons, seaweeds/grasses are consumed by the next level of ecological pyramid, the herbivores, which consists of zooplanktons, parrot fish, oyster, shrimp, clams, crabs scallops, tilapia, lobster, etc. Oceans carnivores... 

Like the zooplankton (see Chapter 26 by Steinberg and Saba, this volume), marine teleost fish are primarily ammonotelic (Wood, 2001), but also can excrete a significant proportion of their TDN as urea or other DON compounds (in both early... 

The relative impact of zooplankton grazing on primary production decreases with increasing production levels the proportion of primary production that is consumed by zooplankton decreases exponentially as productivity levels increase (Calbet, 2001). This supports the observation that the ratio of export production to total production is higher in areas of high productivity. Globally, 12% of marine primary production, or 5.5 Pg C (0.5 Pmol C), is consumed by mesozoo-plankton each year (Calbet, 2001).
