Triggers of Change in Past Ecosystems
This post will go through reasons for changes in past ecosystems for Prelim Biology.
Topic: Past Ecosystems
- Investigate the reasons for changes in past ecosystems, by:
- Interpreting a range of secondary sources to develop an understanding of the changes in biotic and abiotic factors over short and long periods of time
- Evaluating hypotheses that account for identified trends
Changes and Past Ecosystems
This video goes through ecological succession (the gradual change of ecosystems over time).
This video will briefly review abiotic and biotic factors in an ecosystem.
Carrying capacity refers to the maximum number of individuals in a species population due to limitations by environmental factors. This video will go through more detail about carrying capacity.
