Question

level 4 question: question #4 is an optional level 4 question. it can only help you boost your grade and will not hurt your grade. if scientists successfully increased rainfall by 20% in one of the dry regions on the climate zone map, how might this change the local ecosystem, agriculture, and water supply over the next decade? please be sure to identify which dry region (climate zone) you are describing.

Explanation:

Step1: Analyze impact on ecosystem

An increase in rainfall by 20% in a dry - region could lead to the growth of more vegetation as water is a limiting factor in dry areas. This would increase primary productivity.

Step2: Analyze impact on agriculture

More rainfall would likely improve soil moisture, which is beneficial for crop growth. It could potentially increase crop yields and expand the range of crops that can be grown in the area.

Step3: Analyze impact on water supply

The increased rainfall would recharge groundwater aquifers and surface - water bodies such as rivers and lakes, improving the water supply for both human and animal use.

Answer:

The local ecosystem could see increased plant growth and biodiversity. Agriculture could experience higher crop yields and a wider variety of crops. The water supply would likely improve with recharged aquifers and more surface - water availability.
