Except it's way easier to search for Water and oxygen than Chlorophyll.

Suppose it take 5 unit of time to confirm if there's oxygen
Then it take 5 unit of time to confirm if there's water vapor.
And then it take 100 unit of time to confirm if there's Chlorophyll.

You can analyze 10-20 candidates instead of just one.

And like somebody else said, Chlorophyll is one candidate, in other conditions, another chemical could be used.

The solution of this problem is trivial and is left as an exercise for the reader.

Working...
