How does non-human life in an urban ecosystem differ from that in an undeveloped forest ecosystem?

Here is the answer of the given question above.
Often times, non-human life in an urban ecosystem is more disturbed in a way that changes happen rapidly, such as the soil and plant cover and temperature and water availability. In this kind of ecosystem, there is no stability and sustainability. On the other hand, in an undeveloped forest ecosystem, plants play a major role and that, the lives in this kind of ecosystem is undisturbed, making it more ideal for many animals to live. Hope this answer helps.
