Student 3: Organisms within a population do not compete with each other for
resources. INCORRECT

Pick up ½ sheet from the lab desk on “Galapagos Island Tortoises” and complete these
questions.
Tortoises are herbivores. A drought recently hit one of the islands covered by grasses
and low-lying shrubs.
1. Which turtle would survive and reproduce in drought conditions? Explain.
Saddleback tortoise is most likely to survive. Its long neck would allow it to reach
food sources higher off the ground.
2. Which traits would you expect to see in future populations? Explain.
Long neck = reach higher food sources;
Smaller body size = lower energy expended;
Shell with a cutout = can extend its neck for cactus and other drought resistant
plants

List two examples of adaptation that are from:
Natural Selection
1. Giant Owl Butterfly
2. Giraffe
Selective Breeding
1. Race horse
2. Labradoodle

1. How will the use of the insecticide affect traits in future grasshopper
populations?
The grasshoppers that aren’t killed by the insecticide will reproduce and that trait
(resistance to insecticide) will be passed on to its young.
2 How will the use of the insecticide affect the population of tomato plants?
Bees that pollinate the tomatoes are also killed by the insecticide, less plants will
reproduce. This could greatly reduce the farmers tomato crop.
