2. What is an advantage of the mutualistic relationship between angiosperms and animals?

by eating the nutrient-rich pollen

Explanation:

Mutualism is the symbiotic relationship that exists when both organisms benefit from their partnership. During the pollination process, the animals benefit by eating the nutrient-rich pollen and nectar from the flowering plants. The plants benefit because, as their flowers are pollinated, it results in seed production.

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.
