Ozone layer is found in ? ओझोन स्तर कुठे आढळतो ?
- A.
Troposphere / तपांबर
- B.
Ionosphere / दलांबर
- C.
Stratosphere / स्थितांबर
- D.
Lithosphere / भू - आवरण
Correct Answer
C. Stratosphere / स्थितांबरExplanation
The correct answer is Stratosphere. The ozone layer is found in the stratosphere, which is the second layer of the Earth's atmosphere. It is located approximately 10 to 50 kilometers above the Earth's surface. The ozone layer plays a crucial role in protecting life on Earth by absorbing the majority of the Sun's harmful ultraviolet (UV) radiation.Rate this question:

Sound pollution is measured by ? ध्वनीप्रदूषण मोजण्याचे एकक कोणते ?
- A.
Joules / ज्यूलस
- B.
Dynes / डाईन्स
- C.
Hertz / हर्ट्झ
- D.
Decibel / डेसीबल
Correct Answer
D. Decibel / डेसीबलExplanation
Sound pollution is measured using the unit of decibel (dB). Decibel is a logarithmic unit that measures the intensity or loudness of sound. It takes into account the sensitivity of the human ear to different frequencies of sound. Higher decibel levels indicate louder and more intense sounds, while lower decibel levels indicate softer and less intense sounds. Therefore, decibel is the appropriate unit for measuring sound pollution as it quantifies the level of noise that can have negative effects on human health and the environment.Rate this question:

Following type of the ecological pyramid is always upright ? खालीलपैकी कोणत्या प्रकारचा मनोरा हा नेहमी सरळ असतो ?
- A.
Pyramid of biomass / जैव वस्तुमानाचा मनोरा
- B.
Pyramid of energy / उर्जेचा मनोरा
- C.
Pyramid of number / जीव संख्येचा मनोरा
- D.
None of the above / वरीलपैकी नाही
Correct Answer
B. Pyramid of energy / उर्जेचा मनोराExplanation
The pyramid of energy is always upright because energy is lost at each trophic level in an ecosystem. As energy flows from producers to primary consumers, and then to higher-level consumers, there is a decrease in the amount of energy available. This results in a decrease in the biomass and number of organisms at each level, causing the pyramid to narrow towards the top. Therefore, the pyramid of energy is always upright.Rate this question:

Following is a nonrenewable resource ?खालीलपैकी कोणते अपुनर्निर्मितीक्षम संसाधन आहे ?
- A.
Forest / जंगल
- B.
Petroleum / पेट्रोलियम
- C.
Water/पाणी
- D.
Sunlight / सूर्यप्रकाश
Correct Answer
B. Petroleum / पेट्रोलियमExplanation
Petroleum is a nonrenewable resource because it is formed from the remains of ancient plants and animals that were buried and subjected to high heat and pressure over millions of years. Once petroleum reserves are depleted, they cannot be replenished within a human lifetime. This makes it a finite resource that cannot be easily replaced or renewed.Rate this question:

Decomposers / विघटक
- B.
Producers / उत्पादक

Microorganisms that degrade organic matter are called decomposers. These organisms break down dead plants, animals, and other organic material into simpler substances, such as carbon dioxide and water. They play a crucial role in the ecosystem by recycling nutrients and returning them to the soil, making them available for other organisms to use. Decomposers are essential for the process of decomposition, which helps maintain the balance of nutrients in the environment.Rate this question:
