What is Biomass renewable enerygy?4 answersBiomass renewable energy is a crucial non-conventional energy source that has gained increasing attention due to the limited availability of conventional resources and the environmental impact of fossil fuel consumption. Biomass energy involves the conversion of organic materials into heat, power, and transport fuels, contributing significantly to social and economic development. It plays a vital role in reducing greenhouse gas emissions and hazardous materials, thereby improving environmental quality. Bioenergy, derived from biomass, is a prevalent form of modern renewable energy, addressing the global challenges associated with fossil fuel demand and environmental consequences. The utilization of residual and waste materials for bioenergy production requires strategic mobilization and technological advancements to ensure sustainable supply systems.
Define biomass in terms of photosynthesis reaction?4 answersBiomass, in the context of photosynthesis, refers to the organic materials produced through the conversion of carbon dioxide (CO2) and water into organic chemicals using solar energy absorbed by plant pigments. This process, known as photosynthesis, involves the reduction of CO2 and the oxidation of water, resulting in the generation of sugars as initial organic products. Biomass growth through photosynthesis is a fundamental process that utilizes solar energy to convert inorganic materials into a variety of organic compounds, including polysaccharides, lipids, proteins, and other complex organic molecules. The production of biomass via photosynthesis can be enhanced by utilizing microorganisms in a nutrient solution saturated with CO2 and illuminated under controlled conditions. Additionally, the use of microalgae irradiated with light in an aqueous substrate enriched with CO2 can lead to the efficient production of biomass for various applications.
What is woody biomass?3 answersWoody biomass refers to the use of forest trees and residues as a substitute for fossil fuels in order to achieve sustainable development. It is considered a renewable energy source that contributes to the reduction of greenhouse gas emissions, the creation of healthier forests, and the reduction of wildfire danger. Woody biomass can be obtained from waste materials on the land, such as leftover wood that is considered unprofitable to transport. This wasted woody resource can be utilized to increase the supply of woody biomass for energy production. The cellulose and hemicellulose fractions of wood can be used for fermentative production of gaseous biofuels, such as biogas and biohydrogen. However, the recalcitrant nature of wood to enzymatic hydrolysis poses a challenge, and pretreatment techniques are used to improve the deconstruction of wood for fuel production.
What is fish biomass?5 answersFish biomass refers to the total weight of fish in a given area or population. It is an important parameter in aquaculture for measuring fish health, determining feeding patterns, and optimizing stocking density and harvest time. Fish biomass can be estimated using various methods, such as manual sampling, eDNA concentration, and computer vision technology. These methods provide non-intrusive and efficient ways to estimate fish biomass, track growth rates, and establish feeding formulas. Additionally, fish biomass can be utilized to generate revenue by converting fish waste into valuable products such as fish oils, bio-energy, proteins, and organic fertilizers. Accurate and timely information on fish biomass is crucial for the management and sustainability of aquaculture operations.
