Does light factor affect the distribution of organisms? Write a brief note giving suitable examples of plants.

Explanation

Plants require sunlight for photosynthesis. Therefore, light is an important factor that affects the distribution of plants, e.g.
(i) Many species of small plants (herbs and shrubs) growing in forests are adapted to photosynthesis optimally under very low light conditions so, they are seen distributed in shady areas under tall, canopied trees.
(ii) Many plants in the shade will grow vertically to gain access to light. These plants will appear to have smaller leafs than others of the same species of the same age found in conditions with better sunlight.
(iii) Large sized trees will be present in areas that get abundant sunlight.
