Why does population growth increase exponentially?
As the population increases, there are more organisms to reproduce, therefore population grows at a faster rate.
6 of 10
Why would a decrease in light cause a decrease in animals?
Without light photosynthesis cannot occur, so plants would die without glucose production. Then there would be no food for the animals and they would die.

Does increased humidity cause increased or decreased transpiration?
Decrease.
8 of 10
What abiotic factors affect population size?
Light, temperature, pH, water or humidity, nutrient levels.
9 of 10
