bonufazy [111]

The time taken by light to reach pluto will be 5.6 hours.

<h3><u>Explanation</u>:</h3>

The light is a electromagnetic wave that has the highest velocity and same velocity as all other electromagnetic radiations existing in this universe. The light takes about 8.2 seconds to reach from sun to earth. So lets check howmuch time does light take to reach pluto from sun.

The speed of light was calculated to be 3\times10^{8 m/s. This is the speed of each and every electromagnetic waves.

The distance of pluto from sun is huge. On an average it's 6.1\times10^{9 km or 6.1\times10^{12 m.

So time taken by light to reach from sun to pluto will be 2 \times 10^4 seconds. Or actually 5.6 hours.

Do autotrophs need to perform cellular respiration?
nydimaria [60]
Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
