The cystic fibrosis is a condition, in which the secretion of mucus in some vital organs such as lungs, pancreas, and stomach becomes sticky and thick.
This condition is caused by the inheritance of the recessive gene responsible for the development of the cystic fibrosis.

Social factors include how the land is being used and water resources in the area. Five common abiotic factors are atmosphere, chemical elements, sunlight/temperature, wind and water.
Temperature and Light

•••
Temperature of the air and water affect animals, plants and humans in ecosystems. A rise in temperature has the potential to change the way a living thing develops, because it changes the metabolic rate of the organism. All living organisms have a tolerance level for temperature range. For example, a human being would die if he stood out in minus 50 degree temperatures for any length of time. Light exposure often affects the temperature. Areas with direct sunlight are warmer
