Everglades Trophic Levels & Food Pyramids

What is the primary reason the Everglades is dominated by plants?

• The presence of alligators discourages other large animals

• Because plants are the primary producers in the ecosystem

• Due to the large number of herbivores

• Because of the high humidity and rainfall

Why is a food pyramid shaped the way it is?

• It's purely a symbolic representation

• Because of the decreasing number of organisms at each trophic level

• To represent the hierarchical structure of ecosystems

• Due to the increasing amount of energy at each level
