What would be the most likely result of cutting down a tropical forest and planting a beans crop?
A
an increase in available fresh water
B
decrease in biodiversity
C
a decrease in erosion
D
an increase in photosynthetic activity
Explanation: 

Detailed explanation-1: -Deforestation can directly lead to biodiversity loss when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct. Deforestation can lead certain tree species to permanently disappear, which affects biodiversity of plant species in an environment.

Detailed explanation-2: -The roots of rainforest trees and vegetation help anchor the soil. When trees are cut down there is no longer anything to protect the ground, and soils are quickly washed away with rain. The process of washing away of soil is known as erosion. As soil is washed down into rivers it causes problems for fish and people.

Detailed explanation-3: -The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for Indigenous people.

Detailed explanation-4: -Deforestation has a tremendous effect on the biosphere. It leads to carbon emissions, changes in water and other elemental cycles, destruction of habitat, and biodiversity loss. The primary reason for deforestation is the conversion of forested lands to agricultural lands.

Detailed explanation-5: -As vegetation dies, the nutrients are rapidly broken down and almost immediately returned to the system as they are taken up by living plants. Uptake of nutrients by plant roots is facilitated by a unique relationship between the roots and a fungi, mycorrhizae.
