Taxonomy
- Main Page: Taxonomy
Taxonomy is a branch of science focused on the classification of organisms into an ordered system. The system involves grouping organism based on the characteristics they share in common. All organisms within any given group possess features that are common to all members. Each group is then subdivided so as to further distinguish its members based on their differences. This hierarchy of groups and subgroups provides a systematic method for classifying and naming organisms ranging from very general similarities to ever increasingly detailed.

Trophism

There are three basic types of organisms based on their broad trophic level or position within a food chain.
- Producers -- plants which are capable of photosynthesis
- Consumers -- animals, which can be primary consumers (herbivorous), or secondary or tertiary consumers (carnivorous).
- Decomposers -- bacteria and fungi, which degrade organic matter and restore minerals to the environment.
