What would happen to abiotic and biotic factors in galapagos islands if galapagos marine iguana disappeared

The whole habitat will be different and affected for good.

Explanation:

Alike wolves affect and effect the natural woods landscape(as it was not believed before studied carried out by scientists) these consequences will be in the affectations of the whole Fernandina and Isabella islands where these common living organisms would severely affect and destroy the natural resources and abiotic and biotic factors with unsuspected consequences as resulted on those forests like total erosion.

7 - 2/b < 5/b             First, to make our lives easier, lets multiply everything by b.

7b - 2 < 5                 Then we move the 2 over

7b < 7                     Then we divide both sides by 7

b < 1                       Answer.   lets check.  if we plug in a number less than b, the equation should still be correct.  let's try b = 1/2

7 -2/(1/2) < 5/(1/2)

7 -4 < 10

3 < 10   this equation is still correct.  so we know that value of b works.   we know for a fact that b is less than 1.  however we don't know what it's minimum is.  we know that zero doesn't work since 2/0 and 5/0 are both impossible.  what about negative numbers?  lets try b = -1

7 - 2/(-1) < 5/(-1)

7 +2 < -5

9 < -5   this is not true.  if you keep trying all negative numbers don't work.  even negative fractions don't work.  That said.  we can conclude that b has the domain (0,1).  Meaning that b can be anywhere number between 0 and 1.
