Front

What is the impact of drought on ecosystems?

Back

Drought can lead to water shortages, affecting plant and animal life, reducing biodiversity, and altering food chains.

Front

How do pesticides affect ecosystems?

Back

Pesticides can harm non-target species, disrupt food webs, and lead to a decline in biodiversity.

Front

What is the difference between natural and man-made disasters?

Back

Natural disasters are events caused by natural processes (e.g., floods, earthquakes), while man-made disasters are caused by human actions (e.g., oil spills, industrial accidents).

Front

What role do rivers play in ecosystems?

Back

Rivers provide habitats for various species, support biodiversity, and are crucial for water supply and nutrient cycling.

Front

How can urban development impact natural ecosystems?

Back

Urban development can lead to habitat destruction, increased pollution, and changes in local climate, negatively affecting biodiversity.

Front

What is habitat destruction?

Back

Habitat destruction is the process by which natural habitats are altered or destroyed, often due to human activities, leading to loss of biodiversity.
