They provide the foundation of many food webs and animal life would not exist if plants were not around. Note that the Plants, and Green and Red algae are in the same Super Group, but that other algal groups, i.e. The taxonomy is the study of diversity & kind of organism & the evolutionary relationship among them. They are multicellular organisms with the amazing ability to make their own food from carbon dioxide in the atmosphere. Remove all; The Classification Of Plants All living organisms in the ecosystem are classified into kingdoms and sub-kingdoms based on their characteristics. Similarly, plants are also classified into different sub-kingdoms based on certain characteristic features. Introduction.
