during the summer, when the land is brown and the grass is green, the population of mice decreases because mice are easily spotted by the organisms that eat them. how would this change affect the food web? check all that apply. it will increase the grass population. it will increase the fox population. it will decrease the shrew population. it will decrease the snake population. it will increase the grasshopper population.

Answer

Brief Explanations:

  1. Since mice eat grass, a decrease in mouse population means less grass - consumption, so grass population increases.
  2. Foxes and snakes eat mice. With fewer mice, their food source diminishes, so fox and snake populations may decrease.
  3. Shrews don't directly depend on mice, so their population is not directly affected by a decrease in mouse population.
  4. Grasshoppers and mice don't have a direct predator - prey relationship in this context, so grasshopper population is not directly affected by mouse population decrease.

Answer:

It will increase the grass population. It will decrease the snake population.
