HORTICULTURE

Detailed explanation-1: -The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Detailed explanation-2: -External factors that influence photosynthetic rate: temperature, pH levels in the soil, the intensity of the light, weather conditions, and concentration of carbon dioxide.

Detailed explanation-3: -There are many factors that can alter the rate of photosynthesis. However, one that does not affect this process is Humidity.

Detailed explanation-4: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels. Without this process, life on Earth as we know it would not be possible.

Detailed explanation-5: -Answer and Explanation: There are three main factors that affect the rate of photosynthesis. They are light intensity, the amount of carbon dioxide available, and temperature. The greater the light intensity, the more light energy will hit the chlorophyll (pigment) molecules to power the reaction.
