Vermicomposting is a process of decaying waste matter through the use of certain types of worms. Worms help in the conversion of waste materials into fertilizers known as vermicomposts. The fertilizers are the excretion of the worms known as casting. They help in upgrading the soil quality biologically, physically as well as chemically. As the vermicomposts are made through worms, we create a place suitable for worms to survive.

Sample Questions
Ques. Meat involved in composting?
- A) Beetle
- B) Leech
- C) Snail
- D) Earthworm
Click here for the answer
Ans: D) Earthworm
Explanation: Compost is usually organic matter, in most cases it is made of leaves, broken leaves or kitchen remnants. Composting can be done using various agents and in connection with this vermicompost the composting process carried out with the help of worms.
Ques. Vermicomposting is a natural process
- Producing compost
- Waste management creates it
- Producing worms
- Destroying worms
Click here for the answer
Ans: 1) Producing compost
Explanation: The product of the decay process using worms of various kinds is called vermicompost. The most commonly used worms are Red wigglers, white worms and other worms. They form a mixture of decaying vegetables or food items, bedding, and vermicast. The result of the decomposition of organisms by worm-like worms is called vermicast also known as worm castings, a worm compost.
Ques. Kitchen waste and animal feces can be reduced to a great advantage by using
- Vermiculture
- Direct use as biofertilizers
- Biogas production
- Storage in underground storage tanks
Click here for the answer
Ans: 3) Biogas production
Explanation: Animal faeces and kitchen waste are perishable waste and can be reduced when exposed to moisture and sunlight through anaerobic fermentation processes. This is because of the bacteria present in the matter that cause a lack of oxygen. As a result, more methane and nitrous oxide are produced and released into the atmosphere. Biogas is the result of this decay and is a source of energy.
Ques.Which corresponds to vermicomposting
- Algae
- Earthworms
- Nitrifying bacteria
- Fungus
Click here for the answer
Ans: 2) Earthworm
Explanation: Many worm farms grow two main types of worms: Eisenia fetida and Lumbricus rubellus. Many worm farms grow two main types of worms: Eisenia fetida and Lumbricus rubellus. Both are called by a variety of common names, including red worms, red wigglers, tiger worms, brand worms, and compost worms.
Ques.Which can be the best worm for composting?
- Pink worms
- Red wigglers
- Maggots
- Does not matter
Click here for the answer
Ans: 2) Red wigglers
Explanation: The most common type of worm is vermicomposting red wiggler. That is why this method of vermicomposting is also called red worm composting.The red wiggler (Eisenia fetida) likes to live in decaying organisms and manure and is very good at breaking it down.
Ques.In earthworms, typhlosole is a
- Fold of intestine
- Formation of the circulatory system
- Defence mechanism
- Excretory structure
Click here for the answer
Ans: 1) Fold of intestine
Explanation: Typhlosole come from bivalve mollusks, lanterns and other annelids and echinoderms. In earthworms, the back of the intestines travels in length, effectively forming a tube inside the tube, and enlarging the suction area.
Ques. The process by which worms are used to destroy organic waste
- Compost bedding
- Humus forming
- Vermicomposting
- None of the above
Click here for the answer
Ans: 3) Vermicomposting
Explanation: Vermicomposting is a unique process that takes place in the intestines of earthworm to convert waste into natural manure or vermicompost through the combined action of worms and insects.
Ques.What are the main advantages of vermi-culture three-wheeled technology?
- It can be used in both solid waste and liquids
- It cannot be used on both solid and liquid waste
- It involves chemotherapy
- All of these
Click here for the answer
Ans: 1) It can be used in both solid waste and liquids
Explanation: The three-wheeled vermi-culture technology developed by the biotechnology resource centre is relatively inexpensive in terms of conventional methods. Also, operating costs are ignored. But the biggest advantage can be used for both solid and liquid waste. Excluding chemical treatment and disposal of biological waste is not a specialty for vermicomposting.
Ques.Which of the following types of worms should not be used for Vermicomposting?
- Lumbricus Rubellus
- Eisenia Fetida
- Anecic
- Plasmodium
Click here for the answer
Answer: 4) Plasmodium
Explanation: Plasmodium species are a parasite of malaria and not a worm species, while, Lumbricus Rubellus, Eisenia Fetida, Anecic are the most common types of worms used as Vermicomposting earthworms, some with a darker colour and some with a similar colour of growth, digestion rate, and the absorption rate of food eaten by worms is high and can adapt to changing environmental conditions.
Ques.Which of the following is not the main reason for choosing Vermicomposting worms?
- Low incubation time
- Digestion rate
- Adaptability
- Low growth rate
Click here for the answer
Ans: 4) Low growth rate
Explanation: Low growth worms do not appear in the Vermicomposting caterpillars as they have a high growth rate, digestive rate and high levels of dewormed food intake and are unable to adapt to changing environmental conditions, making them highly suitable. for Vermicomposting.
Ques.Which of the following is not the main purpose of Vermicomposting?
- To speed up the deterioration rate
- Raising the number of initial items
- Finding toxic products
- All of these
Click here for the answer
Ans: 3) Finding toxic products
Explanation: Vermicomposting uses worms to make compost by degrading existing waste in a variety of ways and the main purpose is to obtain products without any impurities and as a result, toxic products are eliminated during the process, and the other two purposes of Vermicomposting are. raising the value of the original asset and accelerating the depreciation rate.
Ques. Which of the following methods uses worms during composting?
- Vermicomposting
- Vertical composting
- Windrow composting
- Burning
Click here for the answer
Ans: 1) Vermicomposting
Explanation: Vermicomposting is a method that uses soil worms during fertilization by reducing the amount of waste present in bulk waste, in a direct reactor, the waste flows upwards and that is called Vertical composting, in windrow composting there is a direct contact between the waste and air. However, heat is not a composting process.
Ques.Which of the following can be properly established in the field?
- Eisenia foetida
- Perionyx
- Epifisis
- Anecic
Click here for the answer
Ans: 1) Eisenia foetida
Explanation: Perionyx, Epifilis, Anecic are not suitable for Indian conditions and are often well-established in the field, but are the most common types of worms used as Vermicomposting earthworms worldwide under low temperatures, whereas, Eisenia fetida is the best type of worm and and earthworms. can process organic waste effectively but it cannot be properly established in the field.
Ques.Worms fund burial waste?
- True
- False
Click here for the answer
Ans: 1) True
Explanation: In Vermicomposting, debris is spread over the surface by potentially worms, which can contribute to the accumulation of waste by reducing the amount of debris found in the soil. Eventually they can lead to waste decay in the soil.
Ques.Which of the following is not a method of harvesting or producing worms?
- Homogenization
- Active feeding
- Dry under sufficient light
- Anecic
Click here for the answer
Ans: 1) Homogenization
Explanation: Homogenization can kill worms as the basic goal is to break it down into simple molecules, whereas, food that works to grow worms is then sprayed with compost that is left for a few days and then dried in the light for a few hours. to make the compost right.
