Answer:
b.they're all multi-cellular organisms
Answer:
Explanation:
Base on my understanding of your question, it seems you are comparing susceptibility of disruption of ecosystems with fewer organizations to that of numerous organizations.
Let start from the definition of an ecosystem which can be defined as community of living organisms such plants, animals and non living organisms components in the same environment cohabiting to form a system and are linked together through nutrients and energy cycles. In other word, we can say no organisms exist in isolation and as such they are depend on each others. We also have different type of organisms in an ecosystem which are character as consumer; those that predate on others for their surviver which are known as heterotroph, while some are capable of producing their own food and are termed autotroph either through photosynthesis or chemosynthesis. Some organismsalso feeds on dead things and they are termed Scavengers or detritivores.
So, going by these explanations, ecosystem with few organizations will be more susceptible to disruption because some organisms will go into extinction as they are being eaten up by heterotroph organism and as such themselves will not survived as their will no food for them to feed on again. As such, the cycle will not complete leading to break in nutrients and energy cycles and eventually the ecosystem will be disrupted. While those with many organizations, the cycles continued as the food chain continues and the ecosystem continue to exist.
Answer:
Allopatric speciation
Explanation:
Where a population forms new species due to geographical barrier
That has separated the initial original population into 2 separate population which cannot interbreed
Answer:
it will evolve at a much faster rate through environmental adaption
