How do autotrophic and heterotrophic organisms differ?

• Heterotrophs feed on other organisms.

• Heterotrophs transform inorganic material into organic material.

• Heterotrophs get energy only from plants.

• Autotrophs get energy only from animals.

In which situation would the grasshopper survive longer and why?

• In Situation B, because the plant releases oxygen into the environment.

• In Situation B, because the plant introduces carbon dioxide into the environment.

• In Situation A, because the plant in B absorbs all the available oxygen.

• In both situations the grasshopper will survive the same amount of time.
