Question

question 5
select the false statement about the benefits and impacts of dams.
a dam can create new ecosystems, which increase biodiversity.
a dam can provide a dependable water supply for urban or industrial use.
a dam can provide a means of irrigation to a region with poor or unpredictable rainfall.
a dam can provide hydroelectric power, which is environmentally safer than burning fossil fuels.

Explanation:

Dams often disrupt natural ecosystems. New ecosystems formed may not increase biodiversity as they can fragment habitats, change water - flow patterns, and affect species migration, often leading to a decrease in biodiversity rather than an increase. The other statements about dam benefits are true. Dams can provide water for urban/industrial use, irrigation, and hydroelectric power which is more environmentally friendly than fossil fuels.

Answer:

A. A dam can create new ecosystems, which increase biodiversity.
