In each case, additional videos may be found by typing into your browser:
__________ ecosystem video (insert the desired ecosystem in the blank)
Discuss how each case is an assemblage of plants, animals, and microbes interacting with each other and the abiotic environment in such a way as to sustain the assemblage over indefinite time.
Conspicuously omitted to this point has been discussion regarding how a balance of populations is maintained. This will be addressed in the following lesson, B-32.
Please post questions and/or comments and suggest readings and additional videos.
The Human “Ecosystem”
Likewise omitted is consideration of the “human ecosystem”. I will be adding an additional lesson (B-34) to discuss this.
