Answer:
physical and economic
Explanation:
Physical water scarcity occurs when and where there is not enough water to meet both human demands and those of ecosystems to function effectively. Arid regions frequently suffer from physical water scarcity. It also occurs where water seems abundant but resources are over-committed.
Economic water scarcity is caused by a lack of investment in water infrastructure or insufficient human capacity to satisfy the demand of water in areas where the population cannot afford to use an adequate source of water.

Answer:
<u>Natural selection leads to evolutionary change </u>
Explanation:
- Natural selection is a process by which the species adapt to their environment. Thus individuals have a better chance of survival and evolution and transfer their traits to offsprings.
- As the process of evolution cannot take place without genetic mutation or diversification of genetic buildup. The occurrence of repeatedly branching events take place in which new species splits from a common ancestor producing a multi-level tree.
- For example, in the event of climate change, those species capable of tolerating the temperature will not die as compared to those which are not capable of tolerating and thus will not reproduce.
- If the same process is repeated over millions of years of the time the population will get adapted to their new climate and develop genes that combat these drastic changes.
