- Ethanol from sugarcane has a medium net energy yield, while ethanol from corn has a low net energy yield. Why might this be the case? The energy input for growing corn is lower than that for sugarcane. The energy input for growing sugarcane is lower than that for corn. The EROI for corn ethanol is higher than that for sugarcane.

- What is the importance of decomposition to nutrient cycling?arrow_forwardThere are wastes of four fruits peels; apple, orange, banana, and pineapple were used for this experiment. The percentage of biomass produced and moisture content were calculated by using the given formulas. It is given that the weight of each substrate is equal to 40 grams. The biomass produced is maximum in apple peel followed by banana peel, orange peel, and pineapple peel ( observation 1) and banana peel has highest moisture content followed by orange peel, pineapple peel, and apple peel (observation 2). QUESTION: Please give the clear explanation for both observations and justify your answer.arrow_forwardThe practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship. such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Crop rotation would allow the farmer to reduce which of the following? O Planting seeds. O Watering the fields. O The use of manufactured fertilizer. O The burning of fossil fuels by farm equipment. In the year 2000. specimens of Caulerpa taxifolia,a green alga used in tropical aquariums, were found off the coast of California. Native to the indian Ocean, C. taxifolia is known for aggressive growth and an ability to compete with sea grasses.Jt is currently on an intemational list of invasive species.
