I agree because an ecosystem and a host are basically the same thing.
Some objects in space are created from clouds of gas and dust. A star forms when the mass of the dust cloud is large and has enough hydrogen to start creating a protostar and sustain the nuclear fusion reaction within the core of the protostar. If the dust cloud is not dense enough, then the star formation does not take place, rather a nebula is formed, example the Horse-head nebula. So the answer is (B) A star will not form.
Answer:
Sympatric speciation.
Explanation:
Sympatric speciation is a type of speciation that occurs when 2 types of groups of the common species live in the common geographic location, but they grow differently until they can no longer interbreed and are known as different species.
This speciation can occur in different types of species such as bacteria, the apple maggot fly, and cichlid fish, but it is difficult to tell when this speciation is happening or has occurred in nature. There are four types of speciation occurs:
1) Symmetric
2) Allopathic
3) Parapatric
4) Peripatric.

yes
