<span>An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. </span>

Answer:
A. A2. 10:00 p.m
B. B1. 7:00 a.m
C. C1. 4:00 a.m.
Explanation:
A. Time zone of Bay of Fundy is currently -3 GMT while that of Sydney is +11 GMT.
This means that Bay of Fundy is:
= 11 - (-3)
= 14 hours behind Sydney.
8 am in Bay of Fundi is:
= 8 + 14
= 22:00
= 10 pm in Sydney
B. Chicago is at -5 GMT and Hong Kong is at +8 GMT.
Chicago is:
= 8 - (-5)
= 8 + 5
= 13 hours behind Hong Kong.
8pm in Hong Kong is:
= 20:00 - 13 hours
= 0700
= 7 am in Chicago
C. Los Angeles is at -7 GMT and Moscow is at +3 GMT.
Moscow is:
= 3 - (-7)
= 10 hours ahead of Los Angeles
3 pm in Moscow is:
= 15:00 - 10 hours
= 0500
= 5 am in Los Angeles
This is probably different from options due to Daylight saving time. Pick closest option which is 4am.
