Exploring the Energy Pyramid

The video tutorial explains the concept of an energy pyramid, illustrating how energy moves through different levels in an ecosystem. It highlights the 10% energy transfer rule, where only a small fraction of energy is passed to the next level, with the rest used for life processes or lost as heat. An example calculation demonstrates energy flow from producers to top predators. The video also introduces predator-prey dynamics, encouraging students to explore these relationships through a fun activity.

What is the primary role of producers in an energy pyramid?

• To consume other organisms

• To produce energy through photosynthesis

• To decompose organic matter

• To store energy for future use

Why is the energy pyramid shaped like a pyramid?

• Because it depicts the food chain

• Because it illustrates the flow of water in an ecosystem

• Because it shows the decreasing number of organisms at higher levels

• Because it represents the hierarchy of organisms
