1. Explain how the ecosystem was affected by the missing species for each round of the demonstration.

    a. Round 1 = In this round I removed lichens from the ecosystems. This would have a huge effect on the ecosystem because they play a vital role in the creation of soils which plants obtain nutrients. Taking these out can affect trees and flowers which effect bees that depend on them which effect Humans that depend on the bees for honey and the fruit that the bees help pollinate.

    b. Round 2 = In this round we removed humans. I think removing humans had the littlest effect on the ecosystem. We are the top of the food chain and our actions do more damage then good for the environment.

    c. Round 3 = In this round we removed bees. This is a real problem in today’s environment and effects the pollination of plants. With the removal of bees   it really effects the   ability of plants to produce fruits, which allow humans to get food.

    d. Round 4 =   In this round we removed flowers....
