In the Amаzоn rаinfоrest eаch mоnth: 10% of caterpillars survive and mature into butterflies. Each butterfly lays 200 eggs that hatch and become caterpillars. 30% of butterflies survive Caterpillars do not lay eggs.   Set up the population transition matrix in the form: where the first column represents butterflies transitioning into other states, and the second column represents caterpillars transitioning into other states. Put in the number for each entry: a = [a]     b=[b] c=[c]       d=[d] Some answers might have decimals.
