1.Explain the Biomass Pyramid (in relation to mass and energy usage) using ONE of the following three ecosystems: Eastern Deciduous Forest, Tropical Rain Forest, or Grassland. Draw a food chain, food web, and predict a predator/prey relationship for your particular ecosystem.
2.This question will focus on an alien species being introduced into an area. Mount Saint Helen's in Washington State erupted in 1980. View the following pictures and animation from NASA and describe the ecological succession that has occurred since the eruption. If an "Icelandic Rabbit" and "European Hedgehog" population were released after this eruption (and ground had cooled), would they survive? WHY or WHY NOT? Use literature to support your predictions. See images from NASA website.
