Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Answer: Option (B) and (F)
Explanation:
Pressure and Density, both are inversely proportional to the height.
The air molecules are mostly present near the surface because of its higher density and the gravitational force that forces them to accumulate near the earth's surface. And as we go up, these air molecules gradually decreases in number and their density also becomes very less, as a result of which the pressure and density both subsequently reduces.
Thus, the correct options are mentioned above, i.e the pressure as well as density both decreases with the increasing height.

<span>The answer is all of the above;
Volcanic eruptions can cause debris to flows and make earthquakes happen because of the instability it can bring to the land during lava flow. Lava can also carry some objects to different places.
Another result would be floods and landslides. Volcanic eruptions can pull out trees and plants that can cause erosion and floods. There would be insufficient plants left to consume water from heavy rains. Lava can also cause wildfires in forests.
