Plant Ecology
There are various facets of plant ecology. Some divide the field into two types: autecology (focusing on individual plants and how the environment affects
them) and synecology (focusing on plant communities, how the environment
influences them, and how plant communities influence the environment).
Some others divide the field into several parts: floristics (focusing on the distribution
of plants and considering plants from a numerical point of view),
plant geography (focusing on the distribution of plant communities), and
plant sociology (the same as synecology). All of these require an awareness
of constant change and interactions
