This 34-slide teaching PowerPoint presentation pack covers 4.A.5 (Community Interactions) and 4.A.6 (Ecosystem Interactions) in the AP Biology (2015) curriculum. Each slide includes the 'Essential Knowledge' being covered as well as key terms that students should make note of (editable).
The presentations themselves contains minimal information as they are intended to be used with teacher guidance. There are 'Video' slides throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.
I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the AP Bio Essential Knowledge objectives. The remaining class time is spent reinforcing the knowledge or working on activities geared toward the 'Learning Objectives'.
**These presentations are based on the AP Biology Course Guide and does not follow any textbook
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

The Essential Knowledge covered includes:
4.A.5 - Community Interactions
Communities are composed of populations of organisms that interact in complex ways.
a. The structure of a community is measured and described in terms of species composition and species diversity.
b. Mathematical or computer models are used to illustrate and investigate population interactions within and environmental impacts on a community.
c. Mathematical models and graphical representations are used to illustrate population growth patterns and interactions.
- 1. Reproduction without constraints results in the exponential growth of a population.
- 2. A population can produce a density of individuals that exceeds the system’s resource
- 3. As limits to growth due to density-dependent and density-independent factors are
imposed, a logistic growth model generally ensues.
- 4. Demographics data with respect to age distributions and fecundity can be used
to study human population
4.A.6 - Ecosystem Interactions
Interactions among living systems and with their environment result in the movement of matter and energy.
a. Energy flows, but matter is recycled.
b. Changes in regional and global climates and in atmospheric composition in?uence patterns of primary productivity.
c. Organisms within food webs and food chains interact.
d. Food webs and food chains are dependent on primary productivity.
e. Models allow the prediction of the impact of change in biotic and abiotic factors.
- 1. Competition for resources and other factors limits growth and can be described
by the logistic model.
- 2. Competition for resources, territoriality, health, predation, accumulation of
wastes and other factors contribute to density-dependent population regulation.
f. Human activities impact ecosystems on local, regional and global scales.
- 1. As human populations have increased in numbers, their impact on habitats for
other species have been magni?ed.
- 2. In turn, this has often reduced the population size of the a?ected species and
resulted in habitat destruction and, in some cases, the extinction of species.
g. Many adaptations of organisms are related to obtaining and using energy and matter in a particular environment.
