Ecological Pyramids & Population Growth
by Anonymous
Trace the 10% energy rule up the ecological pyramid, then vary the carrying capacity to see where exponential growth bends into an S-shaped curve.

About this app
An interactive high school biology learning app that connects the 10% energy-transfer rule with population growth and carrying capacity. Explore a four-level energy pyramid, compare exponential and logistic growth at different times, and examine how population size changes when it is below, near, or above carrying capacity. Guided missions, controls, diagrams, and feedback support step-by-step practice.
Use cases
- High school biology students studying ecosystems and populations
- Teachers demonstrating trophic-level energy transfer
- Learners comparing exponential and logistic growth curves
- Classroom activities on carrying capacity and limiting factors
Features
- Four-level energy pyramid from producers to tertiary consumers
- 10% energy-transfer visualization with kcal values
- Toggle between exponential and logistic growth models
- Change time values and view the current point on each curve
- Explore below-capacity, near-capacity, and above-capacity population states
- Review food shortage, predator increase, and disease spread as regulating factors
