I believe the answer is the first one you listed,
Hope this helps..
For cells that are larger, nutrient intake and waste elimination takes a longer time due to the larger distance that must be covered by the same transport processes as the ones taking place in smaller cells. Shapes that maximize surface area help increase the rate of nutrient uptake and waste elimination.
Answer:
Providing energy and regulation of blood glucose.
Sparing the use of proteins for energy.
Breakdown of fatty acids and preventing ketosis.
Explanation:
The main function of carbohydrates is to provide energy and regulation of glucose in the blood. It prevent the use of proteins for production of energy and also promote breakdown of fatty acids and preventing ketosis. Ketosis is a process that occurs when our body doesn't have carbohydrates in sufficient quantity for the production of energy. Carbohydrates are the first biomolecules that are used for energy production.
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.

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

⇒
![Herbivore](https://tex.z-dn.net/?f=Herbivore%20)
The carnivore consumes meat, or other animals such as the herbivore. It's the last.

⇒
![Herbivore](https://tex.z-dn.net/?f=Herbivore)
⇒
![Carnivore](https://tex.z-dn.net/?f=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.
