Q4.13. Scientists are investigating how different ecosystems store carbon as biomass, which could reduce or delay the impacts of climate change. They estimate that the net primary productivity (NPP) of deciduous needleleaf forests is about 0.275 kg C /m2/yr, and that this carbon has a residence time of 160 years. What is the size of the pool of carbon stored as biomass

Resistance than a bicycle? i'm not entirely sure

Producers (autotrophs) are in the bottom (first) trophic level, primary consumers are in the second trophic level, secondary consumers are in the third trophic level and tertiary consumers are in the top trophic level. energy moves through the trophic levels when one living organism is being consumed by another. moreover, energy level becomes lower as it moves up the energy pyramid because of it being released as heat. food chain is when there is a single pathway of energy transfer whereas a food web is when there are multiple pathways of energy transfer.
