The particles of the snow have kinetic energy, but being a solid, it has less kinetic energy than that of liquid water. So they move around in a place about its mean position.
Option C

Explanation:</u><u> </u></h3>
Igloos are the small homes made up of snow. It used to be homes for the people living in Arctic regions in past. Now some tribes still live in these igloos, or they are made by tourists for amusements.
Snow is basically precipitation of ice from clouds. Being the solid form of water, ice has molecules more compactly arranged in its crystal structure. Thus, the molecules cannot move here and there like in fluid. But having some kinetic energy, they have certain movements i.e vibrations around its mean position.
Organisms obtain energy from the foods
Based on the picture, how did the sunflowers show their competition? Why should they compete?
I choose this as a scientific question because there are numerous sunflowers that occupy the land. Living things try to survive with their environmental conditions. Thus, competition happens among the organisms.
The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere. There are a few exceptions to this, such as ecosystems living around hydrothermal vents on the ocean floor, which derive their energy from the chemical compounds such as methane and hydrogen sulfide. In either case, the overall productivity of an ecosystem is controlled by the total energy available.
