Mining that is not well managed often causes ecosystem damage. Analyze how mining activities can affect the water cycle in the area?

• Mining increases water absorption by soil, thus reducing floods.

• Mining activities disrupt the natural flow of water.

Analyze how mining activities can affect the water cycle in the area?

• Mining increases water absorption by soil, thus reducing floods.

• Mining causes erosion and reduces the soil's ability to retain water, disrupting the natural water cycle.

• Mining has no effect on the water cycle as it only digs the soil.

• Mining cleans water from harmful substances, making the water cycle healthier.

How does pollution affect the food chain in river ecosystems?

• Organisms at the top trophic level will die due to the accumulation of toxic substances in their bodies.

• Organisms at the bottom trophic level will reproduce faster.

• Pollution does not affect organisms because they are accustomed to such conditions.

• Pollution increases the number of phytoplankton, making the ecosystem more balanced.
