Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given an ecosystem where the producers are numerous but consist of small, lightweight algae, while the secondary consumers are much larger species like tuna, analyze the implications for the pyramid of biomass and energy.

💡 Hint: Consider how weight versus number affects visibility in pyramids.

Challenge 2 Hard

If an artificial pond created by humans has an overabundance of nutrients leading to high phytoplankton growth, discuss how this impacts the pyramids of number, biomass, and energy.

💡 Hint: What happens when too many producers exist without balance?
