used for photosynthesis. A catastrophic event eliminates all plant life associated with
this food web. Hypothesize as to the result of eliminating all the plants in this
situation.
A) only the fungi would survive
B) the food web would completely collapse
C) birds and nematodes would thrive
D) the food web would produce more bacteria to compensate

1. variations in a population of moths allow for some of its members to be able to adapt to environmental changes. the better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) describe three mechanisms in which variation can occur within a species population. (b) explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. justify your answer.
