These chemicals and metals damage plant cells and hinder them from obtaining the necessary nutrients for growing. This explains why soil pollution also leads to lower yields and poor quality harvests.
What happens when acidic conditions are present in soil?
Acidic conditions accumulate a lot of aluminum ions in the soil, which destroys roots systems and prevents the uptake of important nutrients and ions. 4. Stomata damage. Stomata are the tiny pores on leaves, and they act as sites of gas exchange between the plant and the atmosphere.
Why do leaves die?
Ground-level pollutants like ozone, physically damage the plant leaves, causing chlorosis or an abnormal yellowing of leaves. This results in a deficiency in chlorophyll, meaning the plant will not be able to make its own food or energy. With a higher concentration of ozone, plant leaves will simply die due to too much exposure

It could be air pollution, water pollution, land and soil pollution and even light pollution, all of which have adverse effects on plants. This is a detailed explanation of how these pollutants affect plants.
Why do plants fail to grow?
Reduced yields and damage to crops. Plants absorb pollutants from the air, making the air cleaner. With a build-up of too many pollutants, plants may fail to grow as they should, including being unable to perform photosynthesis. This, in turn, will mean plants will fail to have fewer yields than they should.
How does air pollution affect the ecosystem?
At the ecosystem level, air pollution can shift the competitive balance among the species present and may lead to changes in the composition of the plant community. In agroecosystems, these changes may be manifest in reduced economic yield.
