Problems 25
- What percentage of energy is passed from one level of the food chain to the next? (Producers →\rightarrow→ Primary Consumers →\rightarrow→ Secondary Consumers)
- Which level of the energy pyramid contains the most available energy?
- How much energy is transferred from the producers to the primary consumers?
- What category of organisms lies outside of an energy pyramid and feeds on all trophic levels?
- True or False\text{True or False}True or False === Which of the following statements is false?
- In the picture above, primary producers contain 100% of the available energy for an ecosystem. What trophic level contains 1% of the energy captured by primary producers?
- Why is only 10% of the energy from one trophic level transferred to the next?
- Select the answer choice with the correct energy percentages assigned to each trophic level.
- Imagine this food chain as an energy pyramid. What organism would receive the least amount of energy?
- What percentage of energy does the secondary consumer receive from the original producer?
- What percentage of energy does the quaternary consumer receive from the ecosystem?
- Fill in the blank: When a tertiary consumer eats its prey, most of the energy it consumes is lost woah‾\underline{\phantom{woah}}woah.
- You are stranded on an island and desperately need to eat food. Which trophic level should you eat from to get the most energy?
- Why are energy pyramids pyramid-shaped?
- When a predator eats its prey, only 10% of the energy it consumes is available for it to use to create biomass. What happens to the other 90% of the energy?
- What type of organism is likely to be on the bottom of an energy pyramid?
- What type of organism is likely to be at the top of an energy pyramid?
- What do you call each level of the energy pyramid?
- Fill in the blank: If the photosynthesis of producers is what introduces energy into the pyramid, then insertwordshere‾\underline{\phantom{insertwordshere}}insertwordshere.
- If a plant produces 10 units of energy from photosynthesis, but it has a net primary productivity of 6, how many units of energy did it use in cellular respiration?
- Where in this energy pyramid would you put a producer?
- A lion hunts for his food. For the most part, he is not eaten by any other animals. Where would you place the lion in the energy pyramid?
- What does the size of each level in the energy pyramid tell us?
- Why does the amount of available energy decrease as we move up the energy pyramid?
- How much energy is lost in the form of heat when transferred from one level of the energy pyramid to another?
