HOW DOES ACID RAIN AFFECT PLANT GROWTH?
The harm of acid rain
Acid can harm other plants just like it harms trees. However, food crops are not typically seriously effected by air pollutions because farmers add fertilizers to the soil frequently to replace nutrients that have previously washed away. Limestone is also a common material used in the soil to help increase the ability of the soil to act against acidity.
WHAT IS ACID RAIN
Acid rain is the rain that has been made acidic by certain pollutants in the air. Acid rain has decreased the growth of many forced plants. It has also limited the nutrients available to the plants and exposed them to toxic substances that are released from the soil.
The affects of Acid Rain
Then at the same time acid rain causes the release of substances that are toxic to trees and other plants, such as aluminum, into the soil. Acid rain can also affect the forest floor, then the water pours into the soil, and the soil neutralizes some or all of the acidity of the acid rain. Acid rain can also affect aquatic plants and their growth because the acid dissolves the nutrients they really need like calcium, magnesium, and potassium, which stuns their growth.

Scientists have discovered...
That acid water dissolves the nutrients and helpful minerals within the soil and then washes them away before trees and other plants can use them to grow.
Aquatic Plants
Aquatic Plants have to adapt into their aquatic environment. Aquatic plants are also referred to as macrophytes or hydrophytes. These plants also have special adaptations.
Acid deposition
The gathering of acids or acidic compounds on the surface of earth, in lakes or streams or on objects or vegetation near the earths surface, as a result of their separation from the atmosphere.
How are aquatic plants affected?
Acid rain can also affect aquatic plants and their growth because the acid dissolves the nutrients they really need such as: calcium, magnesium, and potassium, which results to stunted growth.
