3/14/12 A/B DayLEQ: How do we use water as a natural resource and how can we protect it?1. What is a food web? 2. What is a an example of how an aquatic and a terrestrial food web can be interconnected?3. What is an example of an organism you would predict to find in the FIRST trophic level?4. What is an example of a primary consumer?5. Copy and complete: The higher up the food chain, the [higher/lower] amount of energy is transferred.
