Intensity of Light (Sunlight)
This is the amount of sunlight that reaches an area exposed to animals and plants. This element has a direct influence on plants because green plants use it to prepare their own food. This is what we call photosynthesis. But animals indirectly use it by feeding on plants after they have undergone their photosynthesis. Intensity of sunlight of a place is related to the temperature of a place. Thus, the intensity of light also determines the temperature of a place.
The instrument for measuring the intensity of light is called the photometer.

High amount of sunlight affects the growth of plants.
It also affects the destruction of plants and animals
Prolonged sunshine affects flowering plants. It determines how long it takes before plants can bear flowers and fruits.
