Key Topics Covered in an Energy Flow Worksheet and Their Answer Key
Understanding the typical content of these worksheets can help you prepare or create your own. Here are common topics and sample answers.
1. Food Chain and Food Web Diagrams
- Question: Identify the producer, primary consumer, secondary consumer, and tertiary consumer in the diagram.
- Sample Answer:
- Producer: Grass
- Primary Consumer: Rabbit
- Secondary Consumer: Fox
- Tertiary Consumer: Hawk
2. Energy Transfer Percentages
- Question: If a plant captures 1000 units of energy from sunlight, how much energy is transferred to the herbivore that eats it?
- Sample Answer: Assuming 10% transfer efficiency, 100 units of energy are transferred.
3. Trophic Level Efficiency
- Question: Explain why energy decreases at each trophic level.
- Sample Answer: Energy decreases because organisms use energy for life processes, and some energy is lost as heat during metabolic activities.
4. Ecological Pyramids
