True. Metamorphic rocks are pre-existing rocks that have been modified through the exposure to unusual temperatures and/or pressures. It has been used for blackboard, roofs, sidewalks, floors, and marble is an example of a metamorphic rock that is used to make floor tiles, countertops and it is carved into statues and was used extensively in the building of the Roman Colosseum and other historic buildings.

<h2>Answer </h2>
Photosynthesis
<u>Explanation </u>
If the carbon dioxide is present in the stomata that means the process of photosynthesis takes place because in this process the carbon dioxide is absorbed by the leaves through the small pores called as stomata present on leaves. For the plant's grow the carbon dioxide and water absorption is essential and during the process of photosynthesis, oxygen is released which essential for the human body. For the photosynthesis the energy is required which is taken from the sunlight.
