Answer:
Resistant
Step-by-step explanation:
A good aspect of the ecosystem can either be resistant or resilient when there is a disturbance or a form of deviation from the regular occurrence in the ecosystem structure, function, or both.
For an ecosystem to be resistant means it maintains structures and goes on with normal functions despite the disturbance or alteration in environmental circumstances.
Hence, in this case, an ecosystem that retains the structure and continues normal functions even when environmental conditions change is RESISTANT.
