Question
ECOSYSTEM
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.
3.What was the most interesting fact you learned this week? Explain why this was an interesting fact to you.
Explanation / Answer
1. When the new species is introduced in a foreign ecosystem there are several factors that decide weather the new species will survive or replace the ingenious species in the locality. If the new species have abundance of food and no natural predator to maintain the population then the species grows uncontrollably growing to its carrying capacity and probably replacing the ingenious species. The new introduced species doesn't have a place in the natural food chain that is why these problems occur.
The introduction of python in Florida is an example where the python had no natural predator so they grew rapidly to there carrying capacity.
Sometimes the introduced species doesn't have natural food resources available as they were originally present at their natural habitat, when this happens the species struggles for the survival and slowly extincts.
Speciation requires time and if the species survives till the speciation occurs it adapts to the new environment and the makes its way to the natural food chain of that place.
