What is Biomass?
Biomass is a renewable energy source because its supply is unlimited. We will constantly develop trees and vegetation and they will constantly produce garbage. The basic points about biomass are discussed below:
Biomass includes waste from wood, agriculture residues, human manure and organic waste which is from municipal corporation waste.
Be star properly managed and the biomass is considered carbon neutral where carbon dioxide is released during combustion.
Biomass can reduce the dependence on fossil fuels and is also one of the sustainable ways to practice and maintain ecological balance.
It is beneficial for the ecosystem as it helps in balancing out the nutrients.

Advantages of Biomass
Some of the major advantages of biomass are discussed below:
Biomass is a renewable energy source if produced sustainably. Efficient fit ensures that supply matches demand.
In most parts of the world, people use wood or some form of biofuel. The right stove can burn most of these fuels without further processing.
Biomass fuel is generally readily available. Gathering firewood is cheaper than alternative fuels such as gas, wax and electricity.
Biomass fuels are therefore more accessible to the poor. Biomass is within reach of the user. Users are not dependent on suppliers, utilities,, or imports as is the case with fossil fuels.
Fuel preparation activities are often more important than emission reduction technologies.
Types of Biomass
Biomass comes from a variety of sources. Below are some of the different types of biomass:

Disadvantages of Biomass
Biomass utilisation is fantastically environmentally friendly and price range-friendly, relying on the feedstocks and era type used. some of the disadvantages of using biomass are discussed in the following points:
Since the combustion process results in excessive carbon dioxide emissions leading to harmful influences on people, waste electricity biomass production is processed and releases less carbon dioxide, being environmentally pleasing.
Biomass production can pose critical fitness dangers or risks to human health, especially in poorer regions, due to a lack of understanding and appropriate movement.
Depending on the assets used, deforestation, land degradation and auscultation may be the enormous troubles related to biomass production.
Is biomass renewable or non-renewable?
Fossil fuels take thousands or millions of years to produce, trees take only 30 years, and corn stalks are produced yearly. Fertiliser is made daily. Biomass materials can be considered renewable energy sources because they are abundant and easily replenishable.
The general public agrees that biomass is a renewable energy supply. Most people think of biomass as a form of renewable energy because the organic material used to produce energy from biomass can be regenerated in a short amount of time.

Tips, Tricks, and Strategies for Biomass
It takes effort to remember everything in a single go. We made the entire problem easy. Some of the tricks regarding Biomass are given below which you can use to memorise the important points.
Types of Biomass
"FAAWI: Forestry, Agricultural, Animal, Wood, Industrial"
F: Forestry residues (branches, tree tops, sawdust, stumps).
A: Agricultural residues (leaves, stalks, seed pods, stems).
A: Animal waste (excrement, straw, organic residues).
W: Wood wastes (discarded wood products, branches, stumps).
I: Industrial waste (scrap metal, lumber, concrete, chemical residues).
Biomass Conversion
"BCT: Burn, Convert, Transform"
B: Burn directly to produce heat and electricity.
C: Convert into biofuels (ethanol, biodiesel) through fermentation or chemical processes.
T: Transform into biogas through anaerobic digestion of organic material.
Benefits of Biomass
"RCS: Renewable, Carbon-neutral, Sustainable"
R: Renewable energy source, as it can be replenished through proper management.
C: Carbon-neutral (if managed sustainably, carbon released is reabsorbed by plants).
S: Sustainable alternative to fossil fuels, reducing greenhouse gas emissions.

Questions related to
Correct Answer: Both statements are true.
Solution : The correct answer is (a) Both statements are true.
Statement 1 is accurate in defining biomass as a renewable source of energy derived from organic materials like crop residues and wood. Biomass can be sustainably produced, making it a renewable energy source.
Statement 2 is also true as biomass can be utilized in various ways. It can be burned to produce heat for cooking and heating, converted into electricity through processes like combustion or gasification, and processed into biofuels like ethanol and biodiesel.
Therefore, both statements are true as they correctly describe biomass as a renewable energy source and highlight its potential applications in producing heat, electricity, and biofuels.
Correct Answer: Hydroelectric power
Solution : The correct answer is (C) Hydroelectric power
Conventional energy sources typically refer to the traditional and widely used sources of energy that have been utilized for a long time. They are often characterized by their reliance on non-renewable resources.
Hydroelectric power involves the generation of electricity from the energy of flowing or falling water. It is a widely used form of renewable energy and contributes significantly to global electricity generation. However, it is categorized as a conventional energy source due to its long history of utilization and well-established infrastructure.
Correct Answer: biomass productivity
Solution : The correct answer is biomass productivity.
In ecology, biomass productivity is determined by dividing the biomass per unit area by the age of the forest ecosystem. This calculation helps assess the rate at which biomass, or the total mass of living organisms in a given area, is being produced over time in a specific ecosystem. It provides insights into the efficiency of energy transfer and nutrient cycling within the ecosystem.
Correct Answer: Tidal energy
Solution : The correct answer is (C) Tidal energy
Tidal energy is a non-conventional energy source that relies on the tides. It harnesses the kinetic energy of ocean tides and converts it into electricity. Tidal energy is generated by using turbines or other devices that capture the energy of the moving tides. As the tides rise and fall, the movement of water spins the turbines, which then generate electricity. Tidal energy is a renewable and sustainable source of power as it is driven by the gravitational forces of the moon and the sun. It has the potential to provide a consistent and predictable source of energy, especially in coastal areas with significant tidal ranges.
Correct Answer: Geothermal energy
Solution : The correct answer is geothermal energy.
Geothermal energy is a renewable source of energy which is generated inside the earth. It is produced by the radioactive day inside the core of earth. When such energy finds its way through the crust, it can be harnessed as a source for power generation. Manikaran in Himachal Pradesh, Puga valley in Jammu and Kashmir, Tapovan in Uttarakhand etc are some famous geothermal sites in India.
