If decomposers usually grow faster and decompose material more quicklyin warmer ecosystems, why is decomposition in hot deserts relatively slow?

Compare the nitrogen and phosphorous cycles. How are they similar? How are the different? How does the breakdown of organic matter impact both cycles? How would the recycling of nutrients be different in a cold, dry desert compared to a warm, wet rainforest?

Carbon can be sequestered in the ocean in a variety of forms. Discuss the different forms, their biological sources, and how global warming will influence them

Considering the extra carbon created by humans, how might it be possible (or is it?) to generate more means of recycling carbon?

Which lake zone would be absent in a  very shallow lake with good clear water and light can penetrate the entire depth of the lake? aphotic zone benthic zone limnetic zone littoral zone
