B.zooplankton because it’s coming from the phytoplankton
Answer:
Dicot stems have their vascular bundles in a ring arrangement. Monocot stems have most of their vascular bundles near the outside edge of the stem. Monocot roots, interestingly, have their vascular bundles arranged in a ring. Dicot roots have their xylem in the center of the root and phloem outside the xylem.
Answer;
-Over 4000
Mathematically, the biomass in the ocean contributes over 4000 times more grams of NPP per year per gram than an equivalent gram of plant biomass in a terrestrial ecosystem.
Explanation;
-Living biomass forms a tiny fraction of Total Ocean carbon but has a very significant influence on the ocean carbon cycle. Every gram of biomass of the primary producers in the ocean contributes more to NPP per year than plant biomass of terrestrial ecosystems.
-In marine ecosystems, phytoplankton is the main source of primary production. The nutrient availability cycles make it important to distinguish between new and regenerated primary production ; the former identifies the annually renewed nitrogen, while the second measures the rapid cycling of nitrogen through ammonia availability.
