Answer 1

c

Step-by-step explanation:

Answer 2

The correct answer is: C

Step-by-step explanation:

• Agriculture includes the following categories,

1. Production of crops.
2. Production of animals (livestock).
3. Production of fishes.
4. Maintenance of forestry.

• Increase in water scarcity adversely affect crop production as in the absence of sufficient amount of water the crops are unable to grow and produce fruits and grains.
• Overfishing adversely affect the aquatic ecosystem as it disrupts the food chain.
• Decreased soil salinity positively affect all the categories of agriculture as reduction in salt concentration in the soil make it easy for the plants to absorb water from the soil. Also, at lower concentration, the salts do not have any toxic impact on the plants.
• Deforestation causes soil erosion that in turn lowers the soil fertility as the soil is no longer held tightly by the roots of the plants. Also, it lowers the volume of fresh water available in the underground aquifers for human consumption as the roots of the plants are no longer available to hold water molecules between them.
