A rain or other type of precipitation that has increased acidity due to elevated levels of hydrogen ions (low pH). Acid rains are generated in the atmosphere when released sulfur dioxide and nitrogen oxide react with water molecules and produce acids. It has harmful effect on living creatures and infrastructure.

Carbon particles bound to acid fumes as a by-product of incomplete combustion of carbon based fuels. They can induce metal corrosion.
A process of rapid diversification of organisms into new forms, especially when changes in the environment offer new resources and open niches.
The establishment of a forest in an area where there was no forest previously. It can be natural process or part of ecological initiative whose goal is to improve biodiversity.

A measure of health of atmosphere. Air quality shows amounts of pollutants in the atmosphere and estimates the health risk.
A rapid increase in the population of algae in freshwater as well as marine environments. Blooms can be recognized by discoloration of the water, which usually turns green, but it can also become yellow-brown or red in color, depending on the species of algae. Accelerated growth of algae is associated with increased concentration of plant fertilizers in the water.
When studying the ecosystems, we examine the ability of a living organism which can suppress the growth of another organism by releasing some harmful substances. This condition is known as allelopathy.
