Why would a rough steep mountain habitat have a higher rate of satiation than a large open grasslands habitat?

A rough steep mountain habitat may have a higher rate of satiation due to the increased energy expenditure required for movement and foraging in such challenging terrain, which can lead to quicker consumption of available resources. Additionally, the limited availability of food sources in steep areas may encourage animals to consume food rapidly to meet their energy needs. In contrast, large open grasslands typically offer abundant food resources and easier access, allowing animals to graze or forage at a more leisurely pace, potentially leading to lower rates of satiation.
