- There 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.Can you explain the last part of the consumption of berries? I know the fourth level is 0.01% and 100kg biomass but I am not getting those answers. thanks(3) Based upon what we have read, all of the following are potential negative effects of our concentration on growing biofuels (e.g. corn for ethanol production) except: (a) Disappearing Brazilian rainforest used for growing corn (b) Destruction of natural petroleum reservoirs beneath the Alaskan National Wildlife Reserve (c) Decreased resources to fight famine in Africa and other impoverished areas in the world (d) National focus to find or develop practical resources for future energy production
- What is the negative and positive of the biomass?Which of the following equations shows the relationship between gross primary productivity (GPP) and net primary productivity (NPP)? (a) GPP = NPP - photosynthesis (b) NPP =GPP -photosynthesis (c) GPP = NPP - plant respiration (d) NPP =GPP -plant respiration (e) NPP = GPP - animal respirationAlgae in an aquatic food chain convert solar energy into 93, 000 kilocalories of plant tissue. Which of the following values best represents the amount of energy available for secondary consumers in the food chain?

- Given the following information, how do you calculate for the average grams per square meter of dry matter of herbaceous biomass?The chemical reaction equation for the conversion of ethanol (C2H5OH) to acetic acid (CH3COOH) is: C2H5OH + O2 → CH3COOH + H2OIn a vinegar production industry, acetic acid is produced from ethanol during the growth of the bacterium Acetobacter aceti, whose cellular composition is CH1,8O0,5N0,2. The biomass yield from substrate is 0.14 g/g, while the product yield also from substrate is 0.92 g/g. Ammonia is used as a nitrogen source. Based on this information, answer: (a) What is the oxygen demand for acetic acid production in this crop?(b) What are the cooling requirements of a bioreactor containing 3000 L of ethanol (ρ = 789 kg/m³), to be completely converted into acetic acid?what are the methods for the Agricultural residuls (biomass) to be an energy, specifically the bioenergy?
- according to the chart pie 1)what percentage of energy is produced by fossil fuel? 2)what percentage of energy is produced by energy technologies? 3) how much energy is produced by all alternative energy combined? U.S. energy consumption by energy source, 2017 Total 97.7 quadrillion British thermal units (Btu) Total = 11.0 quadrillion Btu geothermal 2 % solar 6% petroleum 37% - wind 21% biomass waste 4% biofuels 21% renewable energy 11% nuclear electric power 9% biomass 45% natural gas 29% wood 19% coal 14% hydroelectric 25%A photobioreactor (PBR) system is used to sequester CO₂ from a small boiler operating at 20 kWth, fired with natural gas and with a capacity factor of 25%. Assuming that the microalgae can grow at 2 g/L-day over 365 days per year and utilize the emitted carbon, calculate the total reactor volume that is needed to sequester 100% of the CO₂ emissions per year. Briefly comment on your answer and potential problems of this CCS method.Combining BioEnergy with Carbon Capture and Storage (BECCS) offers theprospect of energy supply with large-scale net negative emissions and in most of the lower RCPs is required to stay below 2 degrees of global warming. But this entails challenges and risks associated with the upstream large-scale provision of the biomass that is used in the CCS facility as well as those associated with the CCS technology itself. In no morethan 1 page (excluding diagrams) discuss the potential role of BECCS in reducing global greenhouse gas emissions from conventional fossil fuel power stations and what issues or barriers need to be addressed to enable this. Some of the points to be addressed include:i. To what extent the technology has been proven at an appropriate scale.ii. What incentives (e.g. what level of carbon price) would be needed to drive the investment needed.
