Trophic level

The video tutorial explains the structure of a food chain, starting with producers at the first level, followed by herbivores at the second level. It then discusses carnivores, which occupy the third and potentially fourth trophic levels. The concept of top carnivores, which are not preyed upon by other animals, is also introduced, highlighting their position at the highest trophic level.

What is the role of producers in a food chain?

• They produce energy from sunlight.

• They are at the top of the food chain.

• They consume other animals.

• They decompose organic matter.

Which of the following is an example of a herbivore?

• Top carnivore

• Chameleon

• Bird of prey

• Plant-eating insect

What type of animals are found at the third trophic level?

• Decomposers

• Carnivores

• Herbivores

• Producers

What distinguishes top carnivores in a food chain?

• They are not preyed upon by other animals.

• They are producers.

• They decompose organic matter.

• They are herbivores.

If a food chain has a fourth trophic level, what type of animals would you expect to find there?

• Decomposers

• Producers
