by using up heat energy stored in Earth's core by releasing excess energy from the interior of the earth by using up large volumes of nearby atmospheric oxygen by releasing dust that blocks sunlight from reaching Earth
I gave my students this multiple choice question: How does a volcanic eruption interfere with the ability of producers to obtain the energy they need to produce food?

Only one answer is correct among these 4 choices:
- by using up heat energy stored in Earth's core
- by releasing excess energy from the interior of the earth
- by using up large volumes of nearby atmospheric oxygen
- by releasing dust that blocks sunlight from reaching Earth

Could you tell me which one is correct?

by releasing dust that blocks sunlight from reaching Earth
