When the sun is above the horizon and when the sun is below the horizon it is winter
Answer: D
Explanation:
lIf the change in the ecosystem occurs, then it would effect the weather, temperature, and the abiotic factors. So, we can see that the bacteria could survive in any sort of temperature. So, A can't be it. Also, B can't be it because the grass can grow in any sort of soil, even if the soil is contaminated. C cant be it because even if the change in the envoriment (temperature, contaimination) kills of one of the brown bear's food source, they can still have other things they can eat.
