Corn undergoes C4 photosynthesis and does not fix nitrogen, whereas Alfalfa is a nitrogen-fixing plant that utilizes C3 photosynthesis. Both species are equally watered. What can you interpret from this dN/dt vs. N plot given the biculture and monoculture treatments for each species (alfalfa & corn)?
Biculture: Both corn & alfalfa grown together in the same pot
Monoculture: Corn & alfalfa grown in separate pots

- To generate biogas the required biomass resources must be on wet form, else biogas will not produce. How do you disagree or agree with this statement? Justify your answerarrow_forwardChapter 10 of your textbook describes four biogeochemical cycles (some of which might also be called nutrient cycles) which carry elements and compounds essential to life on earth: the oxygen cycle, the carbon cycle, the nitrogen cycle and the phosphorous cycle. Read the sections in the textbook and refer to the diagrams for each of the cycles.These cycles are constantly going on around us. Think about how we are involved in these cycles. What parts of the major biogeochemical cycles do we witness or experience in our daily lives? Give one example per post or response. Think about where the element or nutrient may have come from or where it may go next and whether the process may have been affected by humans and human activities.A simple example (using the hydrologic cycle, which we studied in Chapter 7): Yesterday I was at the beach and witnessed rain falling into the ocean. This is part of the hydrologic cycle.
