Which diagram shows the pathway of energy through an ecosystem?
Iteru [2.4K]
Question 1:
The correct answer should be the one that shows the producer first, (->) followed by the herbivore, (->) with the carnivore last.
Producers are organisms that harvest their own 'food' using things like the sunlight and water. Examples of producers are grass and other vegetation.

Producer
The herbivore, or an organism that consumes only vegetation and/or algae, consumes the producer.

Producer ⇒ Herbivore
The carnivore consumes meat, or other animals such as the herbivore. It's the last. 

Producer ⇒ Herbivore ⇒ Carnivore
Therefore the answer is B.

Question 2:
 I'm pretty sure that succession as well as regrowth after volcanic eruption (Just look at Mount St. Helens. After 30-35 years after the eruption, nature is still recovering) happens over time/slowly. I would say global warming [C](?) would be the answer.
