food chains, food webs

What does every food chain start with (hint: original source of energy)?

• producers
• sun
• consumer
• decomposers

Trophic Level

• The level in a food web in which energy is transferred through
• An organism that eats only plants
• A pyramid
• An organism that makes its own food through photosynthesis

Producer

• interactions between two organisms
• an organism that eats only meat
• herbivore
• An organism that makes it's own food through photosynthesis

The transfer of energy from a lower trophic level to the next highest level is roughly

• 1%
• 10%
• 100%
• 1000%

Which of the following illustrates the correct ordering of trophic levels?

• decomposers-carnivores-autotrophs-herbivores
• herbivores-autotrophs-carnivores-decomposers
• producers-herbivores-carnivores-decomposers
• carnivores-producers-omnivores

In the energy pyramid here, which organisms have the most energy available?

• Producers
• Carnivores
• Herbivores
• Top Predator

If there is 1000 Kcal available in the producers in trophic level 1, how much energy is available in the herbivores in trophic level 2?

• 10 Kcal
• 1 Kcal
• 100 Kcal
• 1000 Kcal

In the energy pyramid below, which organism has the least amount of energy available?

• Producers
• Herbivores
• Carnivores
• Top Predator
