Predict how changing the grass population will affect the other organisms at first. Write + for “Increase” or – “Decrease” next
Afina-wow [57]

Answer: Here you go!

Explanation:

Doubling the amount of grass would definitely increase the rabbit population since there is more food/resources for it to produce. Since the food chain has a domino effect everything else would go up as well because of the increase of food/resources that will help sustain the population of all. so for the first line it would be increase for rabbit snake and hawk. Halving the amount of grass would effect the population of all animals as well. But in a more negative way. It would decrease because the rabbits wouldn't have enough food to produce and thrive. With the decline of rabbits less snakes will live because of the low amount of their main food source. Same with the eagles. So therefore it would be decrease in all the bottom lines.
