AP Success - AP Biology Conceptual Analysis: Systems Interact - Ecology
In a freshwater lake ecosystem, there are several interacting species: algae (primary producers), zooplankton (primary consumers), small fish (secondary consumers), and large fish (tertiary consumers). The lake has recently been affected by eutrophication due to an influx of nutrients from a nearby agricultural runoff.
Question 1
Describe the immediate and potential long-term effects of eutrophication on the lake ecosystem.
Question 2
Explain how the concept of bottom-up control applies to this scenario.
Question 3
Predict the potential effects on the lake ecosystem if the agricultural runoff continues unabated for the next decade.
Question 4
Some ecologists claim that eutrophication can lead to a decrease in biodiversity in lake ecosystems. Justify this claim using the concept of bottom-up control and the data provided.
