describe how energy from the sun is trapped by plants and is eventually used for a person to move his arms?
Answers
Hi,
The energy from the sun is trapped by plants with the help of the chlorophyll in their leaves. This starts the process of photosynthesis which provides energy and food to the plant. Humans then eat plants which they digest to get the energy from it, enabling them to move their arms.
All of this starts when the light from the sun hits the leaf of a plant. The importance of the sun in photosynthesis is that it provides the energy required to breakdown the carbon dioxide and water absorbed by the plant in their surroundings. The plant then proceeds to make food by converting light energy to chemical energy in their leaves. The leaves then send the food to different parts of the plant, which may then be eaten by organisms like humans.
Once the human eats a plant, the energy from the plant is broken down by the digestive system. The process of digestion provides the human enough energy to be able to lift their hands.
Hope it helps!!
Plz mark as brainliest!!!
Some of the heat energy from the sun bounces back off the earth's atmosphere, but some of it gets through and reaches the earth's surface. The energy that does reach the earth's surface warms it. ... Some of the heat energy is trapped by the greenhouse gases in the atmosphere, and the temperature of the earth rises.
