Your teacher wants this answer:
d. less energy available for herbivores and a decrease in herbivore populations
Why that's completely bogus:
One tree can support a lot of aphids, beetles, ants, etc.
Replacing a meadow (lots of individual grass plants) with a forest (some trees) does not necessarily decrease the number of herbivores.

D. Fewer producers means less food for herbivores (less energy available). Without enough food, some will die.
