Question

1. test: click reset. try each experiment with the gizmo. record each result after one year. a. how did increasing the snakes affect the grass? explain why: b. how did increasing the hawks affect the rabbits? explain why: 7. draw conclusions: in general, what effect did removing prey have on predators? what effect did removing predators have on prey?

Explanation:

A. Increasing snakes likely decreased grass. Snakes eat herbivores (e.g., rabbits) that eat grass. Fewer herbivores mean less grass - eating, so grass may grow more.
B. Increasing hawks likely decreased rabbits. Hawks are predators of rabbits. More predators mean more rabbits are eaten.
For removing prey on predators: Removing prey likely decreases predator population as they have less food. For removing predators on prey: Removing predators likely increases prey population as they face less predation.

Answer:

A. The grass likely increased. Reason: Snakes eat herbivores that consume grass, reducing herbivore - pressure on grass.
B. The rabbits likely decreased. Reason: Hawks are predators of rabbits, so more hawks mean more rabbit predation.

1. Removing prey likely decreased predator population due to less food. Removing predators likely increased prey population due to less predation.
