2. A salamander is a keystone species in a forest ecosystem with high biodiversity. This species migrates from woodland areas to a local stream to reproduce. If a road is built that cuts off the woodland areas from the stream, what effect will this have on the forest ecosystem?
no effect because biodiversity is high
no effect as long as the forest is undergoing succession
a negative effect because the salamander’s impact on other species is so large*** a positive effect because the road will cause the salamander to remain closer to thestream
Yes, 3 is right.
You are very welcome.
:-)
1-no effect because biodiversity is high
2-no effect as long as the forest is undergoing succession
3-a negative effect because the salamander’s impact on other species is so large***
4- a positive effect because the road will cause the salamander to remain closer to thestream
thanks ms.sue your the best and thanks you for your time
please be telling the truth Ms. Sue
Are you right???
The correct answer is: a negative effect because the salamander’s impact on other species is so large.
To understand why this is the correct answer, we need to first understand what a keystone species is. A keystone species is a species that has a disproportionately large effect on its environment compared to its abundance. In this case, the salamander is the keystone species in the forest ecosystem. It plays a crucial role in maintaining the balance and health of the ecosystem.
The salamander's migration from woodland areas to the local stream for reproduction is an important part of its life cycle. By building a road that cuts off the woodland areas from the stream, the salamander is prevented from completing its natural migration route. This disruption can have negative consequences for the forest ecosystem.
The salamander's presence in the woodland areas helps regulate the populations of other species, such as insects or small invertebrates. It may feed on these organisms, keeping their populations in check and preventing them from becoming too abundant. Additionally, the salamander may serve as a food source for other predators in the ecosystem.
Without the salamander's presence in the woodland areas, the populations of its prey may increase, leading to imbalances in the ecosystem. This could have cascading effects on other species, disrupting the natural food web and biodiversity of the forest ecosystem.
Therefore, the construction of the road that cuts off the woodland areas from the stream would have a negative effect on the forest ecosystem due to the disruption of the salamander's important role as a keystone species.
