How can the energy stored in the photosynthetic organism be used?

Answers

Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement.

Answers

4 shows convention because the heat is coming from out of the ground into the atmosphere

Arrow 4 show convection. Thus option 4 is correct.

What is convection ?

The process in which transfer of heat occurs by movement of a heated fluid either air or water called as convection.

Initially the heat transfer through conduction, however a bulk heat transfer takes place due to the motion of the fluid.

The mechanism of convection involved,  fluid is heated from below, leads to thermal expansion.

So that the lower layers,  which are hotter now, become less dense.

So the less denser layer replaced by colder layer due to buoyancy nd colder layer is more dense.

This process continuously occur  and heat transfer occur through convection

It  occurs in both liquid and gases, may be natural or forced, bulk transfer occur.

Thus option 4 is correct.

Alveoli has thin walls which are surrounded by blood vessels, and they have maximized are for gas exchange. Thus, option A, B, and D are correct.

These are basic respiratory units, which are balloon like structure present in the lungs, where exchange of gases takes place. A pair of human lungs can contain approximately 480 million alveoli, which produces about, 50 to 75 square meters surface are.

Alveoli are made of thin walls, and they are covered by a rich blood supply through capillaries, this supplies a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.

Therefore, the larger surface area, presence of thin wall, which is only one cell thick,  and rich blood supply due to presence of blood vessels enable them to exchange gases efficiently.
