Answer:
Removing just one species can be a disturbance
Explanation:
Ecosystem consists of a diverse organism and there is a complex interactions between those organisms.For instance if plant species keeps on growing and the animals which exists by consuming these plants suppose if such animal population grows then there will be reduction in the plant population Ecosystem contains many such dependencies.Therefore removing just one species can cause a disturbance to the biodiversity of an ecosystem.
Answer:
The correct answer will be-gas absent in primordial atmosphere (oxygen).
Explanation:
The Miller experiment was performed in 1953 to show that organic molecules can be formed from the inorganic molecules in the conditions resembling the primordial atmosphere.
Same conditions were created to the unstable atmosphere like a mixture of gases which included- methane, sulfur dioxide and hydrogen but lacked oxygen as it was absent in the primordial atmosphere.
Thus, gas absent in the primordial atmosphere (oxygen) is the correct answer.
