Question

How do the availability of water and light and the climate affect the growth of a population?

Answer 1

The availability of water,light and climate are abiotic factors, which limit the growth of a population, because producers are responsible for the synthesis of organic material and transferred along the food chains of an ecosystem, water and light affect the availability of food and a population cannot develop away from the number of individuals the surroundings is able to feed. For example, in the desert, the biomass is relatively small and populations, which live in this ecosystem are smaller. The climate includes the temperature and affects population growth because excessive change in this factor may cause a important decline in a population. Small climatic changes can also modify the process of photosynthesis rate and decrease the availability of food in the ecosystem.
