Assertion: Amount of organic matter synthesized by producers per unit time and per unit area during the process of photosynthesis referred to as net primary productivity. Reason: Primary productivity is usually high and sustained throughout the year in temperate areas due to abundance of sunlight.

Assertion: In a marine aquatic ecosystem, the biomass of phytoplanktons (producers) at any given time, is lower than the biomass of zooplanktons (primary consumers). Reason: Phytoplanktons are consumed almost as rapidly as they are formed and thus have shorter life spans.
