Why would a rough steep mountain habitat have a higher rate of satiation in a large open grassland habitat?

A rough, steep mountain habitat typically presents challenges such as limited food sources and harsher environmental conditions, which can lead to lower rates of satiation among animals. In contrast, a large open grassland habitat offers an abundance of food resources and easier foraging conditions, allowing animals to consume more food quickly and efficiently. This increased availability of resources in the grassland promotes higher rates of satiation, as animals can meet their nutritional needs more readily in such an environment. Additionally, the open space facilitates easier movement and access to food, further enhancing satiation rates.
