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?
A.no effect because biodiversity is high
B.no effect as long as the forest is undergoing succession
C.a negative effect because the salamander’s impact on other species is so large
D.a positive effect because the road will cause the salamander to remain closer to the stream
Your answer?
Right.
i don't have a answer waht is the answer i am haveing troulble at home school help!!!!
what home school im homeschooled to
Oi! @kaif ! Watch your language and mouth! This is a place for School Help, not somewhere for you to be disrespectful!
I think it might be c a negative effect because it has a big affect on other creatures.
its B... I just took the quiz
its B
answers to all of it?
To answer this question, you need to understand the role of a keystone species and the specific relationship between the salamander and the forest ecosystem.
A keystone species is one that has a disproportionately large impact on an ecosystem relative to its abundance. In the case of the salamander, it acts as a keystone species because its migration from the woodland areas to the stream for reproduction plays a crucial role in maintaining the balance and functioning of the forest ecosystem.
If a road is built that cuts off the woodland areas from the stream, this will have a negative effect on the forest ecosystem. By preventing the salamander from reaching the stream, their reproductive cycle will be disrupted. This can lead to a decrease in the salamander population, as well as impact other species that rely on the salamander.
The salamander's migration contributes to the overall biodiversity of the forest ecosystem. It helps in nutrient cycling, as their movements bring nutrients from the stream to the woodland areas and vice versa. This movement also helps disperse seeds and provides a food resource for other species such as predators and scavengers.
Option C, "a negative effect because the salamander’s impact on other species is so large," is the correct answer. The road's construction will disrupt the natural movement patterns of the salamander and can potentially have cascading effects on the entire forest ecosystem, leading to a loss of biodiversity and ecological imbalance.
