Air pollution causes the rain that falls on a pond to become more acidic. Over the next one or two years, how will the acidity most likely affect populations of plants and animals in the pond?

• Populations will increase because the acid carries mineral nutrients into the pond.

• Populations will become extinct because the acid is toxic and destroys their cells.

• Populations will decrease because many organisms cannot tolerate acidic water.

• Populations will increase because acid kills most disease-causing organisms.
