Yo bro The answer for this question is c
Spongy tissues composed of microscopic cells in which inhaled air exchanged for carbon dioxide during one breathing cycle are lungs.
Gaseous exchange is the delivery of oxygen from the lungs to the blood stream, and the elimination of carbon dioxide from the bloodstream to the lungs. It takes place in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
1.) Organisms are producers when they can make their own food.
2.) If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. Such as plants, if they didn't give off oxygen and all plants/ trees didn't exists humans would go extinct because we need air to survive.
3.) They would be affected due to the changes that are happening within the city. (I'm not sure on this one)
By using sunlight, it evaporates the water. As it evaporates, the water vapor rises into the air and it creates clouds.
