Answer

  1. Always upright

Explanation:

The pyramid of energy is upright for any ecosystem including the forests. The producers are at the first level and possess a high amount of energy.

As per the 10% law, there is a decrease in the amount of energy with the increase in the trophic level.

The primary consumer will have energy less than the producer and go on decreasing with the higher trophic levels.

There is a number of plants and trees as compared to carnivores.
