Peering into Mysteries

 

The bigger the plants get, the redder their veins,

 

except for the two damaged plants, the one on the left of which is hanging in there and forming some little buds, and the second from the left, which is drying up and being taken over by tiny black beetles. How do the beetles know which plant is ready to be decomposed?  This whole process has given me goosebumps.  We know nothing.
