Jul 17, 2016 · The ecological importance of photosynthesis. Photosynthetic organisms, including plants, algae, and some bacteria, play a key ecological role. They introduce chemical energy and fixed carbon into ecosystems by using light to synthesize sugars. Since these organisms produce their own food—that is, fix their own carbon—using light energy ...

- Domain. Plural: Domains. The domain is the top taxa in the biological classification system and sits above the kingdom taxa. There are three domains of life.
- Kingdom. Plural: Kingdoms. The kingdom is the second taxa in the biological classification system. It sits below domain and above phylum. There are six kingdoms.
- Phylum / Division. Plural: Phyla / Divisions. Phylum and division are the third taxa in the biological classification system. They sits below kingdom and above class.
- Class. Plural: Classes. Class is the fourth taxa in the biological classification system. It sits below phylum and above order. The ‘class’ taxa is where things get interesting as we can start to see distinct clusters of recognizable lifeforms at this level.
Taxonomy or Plant Systematics, despite what people would have you believe, really is not an exacting science in many ways. This statement mainly applies to the identification process, so we’ll start there. Identification is very different from classification, which is even more problematic. There are several methods for identifying plants.

Feb 28, 2021 · Animals are primarily classified according to morphological and developmental characteristics, such as a body plan. One of the most prominent features of the body plan of true animals is that they are morphologically symmetrical. This means that their distribution of body parts is balanced along an axis. Additional characteristics include the ...
Jan 30, 2023 · Animal – A kingdom of complex multi-celled organisms that do not produce their own food. This kingdom contains all living and extinct animals.
