• Plants make their own food using photosynthesis, which is important not only for the plants themselves, but for the other organisms that feed on the plants.
• The food that plants produce is important, not only for the plants themselves, but for the other organisms that feed on the plants.
• There is an inverse relationship between distance and light intensity, meaning that as the distance from a light source increases, light intensity decreases.
• This is because as the distance away from a light source increases, photons become spread over a wider area.
• The light energy at twice the distance away is spread over four times the area.
• The light energy at three times the distance away is spread over nine times the area, and so on.
• The light intensity is inversely proportional to the square of the distance, which is the inverse square law.
