• An animal that eats other animals
  

• A plant that makes its own food
  

• A decomposer that breaks down dead things

•  A type of consumer

4.What happens if a primary consumer, like the grasshopper, is removed from the food chain?

• The food chain remains unaffected
  

• Other consumers may not have enough to eat
  

• The environment will improve
  

• It will cause a decrease in plants

7. Why is biodiversity important for an ecosystem?

• It makes the ecosystem weaker
  

• It helps organisms survive changes in the environment
  

• It only benefits producers
  

• It has no effect on the ecosystem

10. What is one benefit of high biodiversity mentioned in the video?

•  It only benefits plants
