Apopulation of frogs inhabits a lake. if the resource availability of the lake changes, the population may to use the resources that are available. as a result, the population would exhibit .

Resources in a lake can change due to climate changes. Changes in climate may affect the survival, growth and reproduction capabilities of frogs and other amphibians. Climate changes greatly influence food availability, predator-prey relationships and competitive interactions which can alter community structure.

Changes in lakes can include other factors such as UV-B radiation and contaminants.These factors are complex and are causing some amphibian population to decline or even extinct.

Hence, as a result the frog population could exhibit a decline in population.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
