Answer:
A specific environmental factor that will cause a response to living things would be temperature.
Explanation:
Temperature can be described as the amount of heat present in an organism. The heat usually arises from environmental sources like the Sun.
A rise in temperature to moderate amounts will cause the plant cells to have enhanced photosynthesis. A moderate rise in temperature will also cause the germination process to be faster.
In animals, a rise in temperature will cause vasodilation. A fall in temperature will cause vasoconstriction.
