ENVIRONMENTAL SCIENCE WEEK 2 DISCUSSION 2 FOR PRO ELUID P ONLY

1: What problems arise when a species is introduced from a foreign ecosystem and why do these problems occur? If a species is introduced to new environment, what factors determine whether the species will adapt to its new environment? Once introduced to a new environment, can a species undergo changes that eventually create a new species (speciation)?

2: Describe how differences in climate cause Earth to be partitioned into major biomes. Then explain why tundra and desert ecosystems support a much smaller animal biomass than tropical rain forests. Lastly, identify and describe the biotic and abiotic components of the biome where we live.
