Part I: Launch the Coral Reefs 2 - Biotic Factors simulation. Play around with it for about 10

1. What does the simulation model? How do the components of the simulation model these ideas?
Give an example to support your answer.

Flock x flock y flock z total pieces of food eaten (from previous page) 147 93 60 food percentage* % % % simulated number of birds in flock for 3rd generation** * divide each flock's total pieces of food by 300, the total number of pieces of food eaten. ** multiply the food percentage for each flock by the total number of birds (30).

2. if someone had the list of traits you provided in question 1, do you think he or she would be able to find you in a group of 1000 people? why or why not? if not, what other information encoded in your genes might distinguish you from the others in the group? what are other traits that are encoded for by dna?
