Explain the effect of decreased rainfall in an area on photosynthesis
Answers
Photosynthesis is a biological process used by plants to prepare food with the help of sunlight water and carbon dioxide. The name photosynthesis is derived from the Greek word ”Photo” meaning light and “Synthesis” meaning connecting together. This means combining together with the help of light energy.
This process is also used by algae and several bacteria to convert solar energy into chemical energy. Oxygen is liberated as a by-product, and light is considered as the major factor to complete the process of photosynthesis. This process occurs usually when plants use light energy to convert carbon dioxide and water into glucose and oxygen gas. Leaves are made up of small cells which have a tiny structure known as chloroplasts. Each chloroplast contains a green colored pigment called chlorophyll. Light energy is absorbed by chlorophyll molecules whereas carbon dioxide (CO2) and oxygen (O2) enter through the tiny pores of stomata located in the epidermis of leaves.
