Durable good. A car is a durable good. The gasoline that powers it is a non-durable good, or consumable good. In economics, a durable good or a hard good is a good that does not quickly wear out, or more specifically, one that yields utility over time rather than being completely consumed in one use. Items like bricks could be considered perfectly durable goods because they should theoretically never wear out.
Photosynthetic Protists. These protists belong to a division called Pyrrophyta of algae. They are a well defined group of unicellular, photosynthetic forms. Most of them are flagellated and motile but some forms are non-flagellated.
Photosynthetic Bacteria. Photosynthetic bacteria are a unique species of microorganisms that use the sun as a source of energy. Plants use a substance called chlorophyll to absorb the sunâs rays and turn it into the nutrients needed for everyday maintenance and growth.his is a short summary of the definition of photosynthesis, the different types of photosynthetic bacteria and how they differ from each other. It is important to note that other photosynthetic bacteria may exist and have not been identified yet.
