Answer:
Plants take carbon dioxide out of the atmosphere, but they also have other effects, such as changing the amount of evaporation from the land surface. ... The plants absorb carbon dioxide for photosynthesis through the same pores (called stomata). But when carbon dioxide levels are high, the leaf pores shrink.

Explanation:
Compound
A compound contains atoms of different elements chemically combined together in a fixed ratio.
Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined.
A compound can be separated into simpler substances by chemical methods/reactions.
A huge, virtually limitless, number of chemical compounds can be created. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes.
A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound
Element
An element is a pure chemical substance made of same type of atom.
Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.
Elements cannot be broken down into simpler substances by chemical reactions.
There are about 117 elements that have been observed. Can be classified as metal, non-metal or metalloid.
An element is represented using symbols.
