The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
The simplest organisms are cells.
A cell is: The smallest structural and functional unit of an organism.
The principle of faunal succession<span>, also known as the law of </span>faunal succession<span>, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that </span>can<span> be identified over wide horizontal distances.</span>
