Question

1. predict: predict how changing the snake and hawk populations will affect the other organisms within the first year. in the tables below, write your predictions.

change	grass	rabbits
halving snake population	prediction: result	prediction: result

change	grass	rabbits	snakes
halving hawk population	prediction: result	prediction: result	prediction: result

Explanation:

Step1: Analyze doubling snake population

Snakes eat rabbits. More snakes mean more rabbit - predation. Fewer rabbits mean less grass - consumption.

Step2: Determine grass and rabbit results

Prediction for grass: Increase. Result: With fewer rabbits eating it, grass has less predation. Prediction for rabbits: Decrease. Result: More snakes preying on them.

Step3: Analyze halving snake population

Fewer snakes mean less rabbit - predation. More rabbits mean more grass - consumption.

Step4: Determine grass and rabbit results

Prediction for grass: Decrease. Result: More rabbits eating it. Prediction for rabbits: Increase. Result: Less snake - predation.

Step5: Analyze doubling hawk population

Hawks eat snakes. More hawks mean less snakes. Less snakes mean more rabbits and more rabbit - consumption of grass.

Step6: Determine grass, rabbit and snake results

Prediction for grass: Decrease. Result: More rabbits due to fewer snakes. Prediction for rabbits: Increase. Result: Less snake - predation. Prediction for snakes: Decrease. Result: More hawk - predation.

Step7: Analyze halving hawk population

Fewer hawks mean more snakes. More snakes mean less rabbits and less rabbit - consumption of grass.

Step8: Determine grass, rabbit and snake results

Prediction for grass: Increase. Result: Fewer rabbits due to more snakes. Prediction for rabbits: Decrease. Result: More snake - predation. Prediction for snakes: Increase. Result: Less hawk - predation.

Answer:

Change	Grass	Rabbits	Snakes
Halving snake population	Prediction: Decrease <br> Result: More rabbit - consumption	Prediction: Increase <br> Result: Less snake - predation	-
Doubling hawk population	Prediction: Decrease <br> Result: More rabbit - consumption	Prediction: Increase <br> Result: Less snake - predation	Prediction: Decrease <br> Result: More hawk - predation
Halving hawk population	Prediction: Increase <br> Result: Less rabbit - consumption	Prediction: Decrease <br> Result: More snake - predation	Prediction: Increase <br> Result: Less hawk - predation
