The earth underneath is usually older and newer earth is typically found on top.

The carbon dioxide that the plants intake clean the air and remove pollution. the plants release oxygen into the air as photosynthesis occurs, giving other organism the air they need to breathe. the sugars that the plant creates gives it energy and create carbohydrates in food producing plants.  chloroplasts, are located in the leaves of most plants, are organelles found inside of mesophyll cells and are where photosynthesis actually takes place.pigments absorb the sunlight into the photosynthetic organism.  stomates are found primarily in the lower epidermis of leaves. stomates are small holes that open and close as needed to allow co2 to enter and o2 to exit.hope my answer is what you are looking for : )
