The bigger the distance between the lit torch and the screen, the bigger the illumination area.
Explanation:
Part of the reason is that with increasing distance the light, beam interacts with air molecules that disperse it. The more the air molecules (and note that these air molecules have kinetic energy) it interacts with, the higher the dispersion. It is also important to note that light waves have duality. They also behave like a wave. As a wave disperses from a single point (the torch), it propagates outwards in all direction. The area covered, therefore, increases with distance. Its intensity will also decrease with distance.
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants
Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air and gets rid of carbon dioxide.
