(Select all that apply), language that allows communication symbolically Among all domains in the biological world, Eukarya members have the most significant body size and body mass. The approximately 250,000 species of plants are organisms that make their own food through the process of photosynthesis. Bacteria are also important for the recycling of nutrients in the global ecosystem as they are primary decomposers. This means that when your body converts 100 J from metabolizing fat, 20 J goes into doing mechanical work (here, climbing stairs). As a result, the resulting cells could now produce their energy and fix carbon through the use of light. Algae, diatoms, dinoflagellates, and euglena are only a few examples of photosynthesis-capable protists. Other organelles function for support and motility. These organelles could not be digested, and as a result, they now are commonplace inside of the cell, and each carry out specific roles. On the other hand, all living organisms belong to three domains namely, bacteria, archaea and eukarya.
