Which of the following best explains how trees conserve energy and reduce pollution in cities? a. trees shade buildings which reduces the use of energy derived from fossil fuels. b. trees remove carbon dioxide and add oxygen the atmosphere. c. trees filter particulates and polluting gases from the atmosphere. d. all of the above

a. Trees shade buildings which reduces the use of energy derived from fossil fuel.

Trees shade buildings and provides thermal insulation in winters and provide shade against excess heat from the sun in summers. The fossil fuels are required to produce energy in the form of electricity, which is utilized as a source of energy for maintaining household temperature like heating from heater or other appliances or cooling from air conditioners which requires fossil fuels like natural gas, coal and petroleum. Trees maintains the temperature balance by providing shade. Hence, conserves energy and prevents burning of the fossil fuels. This reduces pollution in the cities.
