In terrestrial habitats, temperature and rainfall conditions are influenced by transpiration. Transpiration increases the water content in the air, due to which temperature decreases and rainfall occurs.
- Water vapour acts as an important greenhouse gas, and increased concentration of water vapour leads to maintenance of temperature due to the greenhouse effect. Also, loss o water vapour during transpiration leads to cloud formation.
- The rate of transpiration is directly proportional to the saturation deficit of the atmosphere.
- Climate is the most important abiotic factor affecting the distribution of terrestrial biomes.
- Warm air can hold more moisture than cold air, so tropical areas receive more rainfall than other parts of the world.
