The rabbit population may increase
The rabbit population may decrease
The rabbit population may increase first, then decrease

Adult lions have no predators in the wild.
Adult lions are prey for many different kinds of animals.

another.
Matter can be recycled between organisms

the right?
Sun
Orca
Seal
Larvae
Which organisms compete for food in the food web to the
right?
Orca and Herring
Seal and Copepod
Killifish and Snapper
Mackerel and Bluefish

If the GRASS became diseased, which organisms would also be NEGATIVELY affected?
Rabbits only
Rabbits and snakes
Rabbits, snakes, and hawks
Rabbits and hawks (snakes benefit)
If the RABBITS became diseased, which organisms would also be NEGATIVELY affected?
Grass and hawks
Grass and snakes
Grass, snakes, and hawks
Snakes and hawks
If the RABBITS became diseased, which organisms would also be POSITIVELY affected?
Grass
Snakes
Nobody (all hurt)
Hawks
What happened after 12 months after the hawk population was MOSTLY killed off?
Snakes increased, Rabbits decreased, and Grass increased. Then everything balanced back out to almost normal.
Initially everything was stable, but the snake population killed all the rabbits and then died out themselves.
Everything went down significantly at first, then the hawks recovered.
Everything except the grass died off at first, then the rabbits recovered.
Which of the following is not true about predator-prey relationships?
Predators lower the size of prey populations
If a prey population grows, the predator population will grow too
Predators hunt/eat prey.
If a predator is removed, the prey population will die off.
What is the effect of removing prey from a food chain?
All predators above them will die or suffer.
The prey's predator will die or suffer, but everybody else should be fine.
