Solar Radiation and Energy Questions

Multiple choice zoology meaning of life energy flow and loss energy flow in a food chain energy flows

The correct sequence of components through which energy may pass from initial source, through an ecosystem is

  1. Sun $\rightarrow$ Autotrophs $\rightarrow$ Heterotrophs $\rightarrow$ Environment $\rightarrow$ Space
  2. Space $\rightarrow$ Environment $\rightarrow$ Heterotrophs $\rightarrow$ Autotrophs $\rightarrow$ Sun
  3. Sun $\rightarrow$ Space $\rightarrow$ Environment $\rightarrow$ Heterotrophs $\rightarrow$ Autotrophs
  4. Sun $\rightarrow$ Space $\rightarrow$ Environment $\rightarrow$ Autotrophs $\rightarrow$ Heterotrophs
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The energy flow starts from the sun. The light energy enters the space and then into the atmosphere. The energy in the atmosphere is captured by the plants which are autotrophs. Plants convert this light energy to chemical energy by photosynthesis. The food prepared by the plants is consumed by the heterotrophs. The heterotrophs are utilized by the decomposers.

So, the correct answer is option D. 

Multiple choice physics energy management solar power plant production of electricity from solar energy solar energy and its applications

State whether true or false :
Solar dryer works on the principle of conversion of solar energy into heat energy.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The basic function of a solar dryer is to heat air to a constant temperature with solar energy hence Solar dryer works on the principle of conversion of solar energy into heat energy.

Multiple choice

T/F: Living things cannot gain energy from the Sun.

  1. TRUE

  2. FALSE
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Living things, specifically producers like plants, capture solar energy to sustain life on Earth. Therefore, the statement that they cannot gain energy from the Sun is false.

Multiple choice

What are 3 ways that energy can be transferred through Earth's system?

  1. polarization, refraction, diffraction

  2. conduction, expansion, polarization

  3. radiation, conduction, convection

  4. radiation, absorption, expansion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The three primary methods of heat transfer are radiation, conduction, and convection. These processes are essential for distributing energy throughout Earth's systems.

Multiple choice physics the essence of change different forms of energy energy conversions energy transformations and energy transfers

A solar water heater converts

  1. Light energy into heat energy

  2. Heat energy into light energy

  3. Chemical energy into heat energy

  4. Light energy into electrical energy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Solar heater absorbs light, and thus photons of light are absorbed and the energy contained in them is converted to heat energy, which raises the temperature of water flowing slowly in contact with the plate and thus heat energy is transfered from plate to water.

Hence a solar heater converts light energy into heat energy.
Option A.

Multiple choice physics the essence of change different forms of energy energy conversions energy transformations and energy transfers

A plant usually stores its carbohydrates in its fruits. This process also shows the conversion of  _______ energy to _______ energy.

  1. kinetic to potential

  2. mechanical to chemical

  3. solar to chemical

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Plant takes heat from the sun in form of solar energy and using photosynthesis process, this energy is converted to carbohydrates.
