Answer:
Increase in high temperature.
Explanation:
The population of the thermophile bacteria increase at high temperature as compared to other bacteria at high temperature because thermophile bacteria needs high temperature for growth and survival. Thermophile bacteria that flourish at relatively high temperatures ranging from 41 to 122 °C (106 and 252 °F) so we can conclude that the thermophile bacteria increase in population in the high temperature conditions.
