Final answer:
Estivation is the type of dormancy associated with hot and dry conditions, such as during summer months, helping animals like lizards conserve energy and water.
Step-by-step explanation:
The specific type of dormancy in response to hot/dry conditions during summer months is called estivation. Estivation is a state where an animal's metabolic rate significantly decreases to conserve energy and reduce the need for water. For example, a lizard entering estivation would become lethargic, its body functions would slow down, and it would likely seek out a cool, moist location to help conserve its body's water reserves. Such behavioral changes are critical for survival during periods of extreme heat and limited water availability.
