MCQ Questions on Sources of Energy Class 10 Question 26. The amount of sunlight received on Earth's surface is affected by the reflectivity of the surface, the angle of the sun, the output of the sun, and the cyclic variations of Earth's orbit around the sun. Plants and eaten by animals. The energy stored in the glucose ( potential chemical energy transduced from radiant energy ) is converted to spendable enrgy currency ( ATP) by a … Sun provides us with light and heat. Yes, sun is the ultimate source for not only fossil fuels, but for every form of energy present on Earth. The animals also eat plants, so the animal material also a store house of Sun's energy. (a) Water (b) Sun (c) Uranium (d) Fossil fuels; Which one of the following forms of energy leads to least environmental pollution in the process of its harnessing and utilisation? Q1. Animals eat other animals. These plants prepare their own food in the presence of sunlight. Q3. (b) Sun is the ultimate source of energy directly or indirectly, all the form of energy are desired from solar energy. We can prove that the sun is the ultimate source of energy by the following food chain. Which one of the following forms of energy leads to least environmental pollution in the … Examples given include how the sun makes cars able to function and why crisps are a product of the sun. The Sun is the ultimate source of energy for living things. Yes, its true that all life on earth is bottled sun's energy or sun is the ultimate source of energy on earth. For example the energy which moves in the trophic levels all comes form the sun (plants produce their food by converting sun's energy and animals eat those plants).In this way, energy is stored in the animal's or plant's body. Because the radiant energy of the sun is captured or fixed into glucose /plant starch dring photosynthesis. The Sun's energy drives the climate system. The sun's radiation interacts with Earth's atmosphere and lifeforms to act as the main source of energy. The sunlight is converted into food energy by plants. The sunlight is converted into food energy by plants.

'Sun is the ultimate source of energy for all living organisms'.Justify. Learn the basics of how the Sun serves as the ultimate energy source for much of the energy we use, including fossil fuels, from the National Academies, advisers to the nation on science, engineering, and medicine. That is, for those organisms that live on or near the surface of the world, in the sunlight. The Sun is approximately 865,000 miles wide, and roughly 74 percent of its mass is made up of hydrogen. The first level of the food chain is occupied by the producers. All of this begins with sunlight. The Sun is approximately 865,000 miles wide, and roughly 74 percent of its mass is made up of hydrogen. If you push a crate horizontally with 100 N across a 10-m factory floor and the friction between the crate and the floor is a steady 70 N, how much kinetic energy does the crate gain? Farmers can reduce the use of nitrogenous fertilisers where legumious plants are grown.Give Reasons. Fungus eat the decaying plants and animals. We known that all living beings are directly or indirectly dependent on plants for food. Animals eat other animals. These plants and animals which were originally made by using Sun's energy have been converted into fossil fuels. Solar radiation travels in straight waves. The Sun is the ultimate source of energy for living things. Q2. Fungus eat the decaying plants and animals. Find resources here to help students use real-time data to learn about the relationship between the sun, weather, and climate. Sun is the ultimate source of energy: • Sun is the ultimate source of energy for all organisms. So, if there is no sun, no photosynthesis leading to the death of all plants.

(a) Sun can be taken as an inexhaustible sour ce of energy (b) There is infinite storage of fossil fuel inside the earth (c) Hydro and wind energy plants are non polluting sources of energy (d) Waste from a nuclear power plant can be easily disposed of f 13. What are the functions of chlorophyll? Which is the ultimate source of energy? Yes, sun is the ultimate source of energy. Here we have given NCERT Exemplar Class 10 Science Chapter 14 Sources of Energy. Plants and eaten by animals. (a) Nuclear energy (b) Thermal energy (c) Solar energy (d) Geothermal energy; Ocean thermal energy is due to
