Ecological Pyramids & Population Growth
by Anonymous · ⭐ 1 · 🍴 0
At every step up the food chain 90% of the energy is lost as heat and only 10% moves on. Watch the pyramid narrow from producers to tertiary consumers, compare runaway exponential growth when resources are endless with the S-shaped curve when they run short, then change the carrying capacity and see where the population settles.
About this app
Ecological Pyramids & Population Growth is an interactive high-school biology learning app covering energy transfer through trophic levels, population growth models, and carrying capacity. Explore how only 10% of energy moves to the next level, compare exponential and logistic curves at different times, and examine how populations respond when they are below, near, or above carrying capacity. Guided missions provide specific settings to investigate each concept.
Use cases
- High-school biology students studying ecosystems and populations
- Teachers demonstrating energy pyramids and growth curves
- Learners comparing exponential and logistic growth
- Anyone reviewing carrying capacity and population regulation
Features
- Interactive producer, primary consumer, secondary consumer, and tertiary consumer energy levels
- Displays the 90% heat loss and 10% energy-transfer rule with energy values
- Switches between exponential and logistic growth models
- Adjusts time to view changing population values and curve positions
- Compares population states below, near, and above carrying capacity
- Explores food shortage, increased predators, and disease spread as regulating factors
