PLEASE HELP ME WITH SCIENCE WILL MARK BRAINLIEST! 1: What gases are used and expelled by photosynthesis and respiration?

2: Where are the largest concentration of ozone and what value does it have?

3: What happens to the surface of the earth when there is an increase in greenhouse gases?

1 Photosynthesis uses CO2 and expels O2 and the reverse for respiration

2. stratosphere where ~90% of it is

3. Less infrared radiation is able to escape from the earth into space and that infrared radiation hits the GHG gases and the radiation is turned into kinetic or heat energy trapping which warms up the earth

Explanation:

1. Used by Photosynthesis: CO2  Expelled: O2

Used by Cellular respiration: O2 Expelled CO2

2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”

3. The surface of the earth heats up

Explanation:

multiplying and dividing the two decimals and the eqations by the same number of the overalls

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
