What is most likely to result immediately after a rainforest in Brazil is clear-cut?
A
An immediate increase in soil fertility
B
The formation of a new rainforest ecosystem
C
A rapid loss of biodiversity due to habitat destruction
D
A sudden decrease in atmospheric carbon dioxide levels
Verified step by step guidance1
Understand the context of the problem: Clear-cutting a rainforest involves removing all trees and vegetation from an area, which has significant ecological consequences. Rainforests are biodiversity hotspots and play a critical role in maintaining global ecological balance.
Analyze the options provided: Evaluate each option based on the ecological impact of clear-cutting. For example, consider whether soil fertility would increase or decrease, whether a new rainforest ecosystem could form immediately, or whether atmospheric carbon dioxide levels would change suddenly.
Focus on the most immediate consequence: Clear-cutting destroys habitats, leading to a rapid loss of biodiversity. This is because many species depend on the rainforest for shelter, food, and reproduction, and their survival is directly impacted by habitat destruction.
Consider the role of rainforests in carbon storage: Rainforests act as carbon sinks, absorbing large amounts of carbon dioxide. Clear-cutting releases stored carbon into the atmosphere, contributing to increased carbon dioxide levels rather than a decrease.
Conclude that the correct answer is the rapid loss of biodiversity due to habitat destruction, as this is the most immediate and direct consequence of clear-cutting a rainforest.
