10% Rule and Energy Pyramids

What is the 10% rule?

• The 10% rule states that 10% of a population can survive in extreme conditions.
• The 10% rule indicates that 10% of resources are allocated to the top management.
• The 10% rule suggests that only 10% of species can coexist in an ecosystem.
• The 10% rule states that only 10% of energy is transferred from one trophic level to the next in a food chain.

Why is the 10% rule important?

• It helps in understanding energy transfer in ecosystems.
• It determines the size of animal populations.
• It outlines the carbon footprint of humans.
• It explains the water cycle in nature.

An energy pyramid represents what?

• How much sunlight is available for the ecosystem to use. 
• How much energy a particular organism needs. 
• How much energy is needed to build a pyramid. 
• The amount of energy available to the next 'consumer' in a food web.
