Answer:

Option D: (A) is false, but (R) is true

Detailed Solution:

The correct answer is “(A) is false, but (R) is true”.

Ecosystems are highly interconnected and interdependent. Each component, from producers to decomposers, plays a crucial role in maintaining the balance and functioning of the ecosystem.

Human activities have a significant impact on the environment, often leading to negative consequences such as pollution, deforestation, and climate change. These actions can disrupt the delicate balance of ecosystems and have far-reaching effects.
