Some desert mammals can obtain their water from breaking down stored body fat - HSC - SSCE Biology - Question 2 - 2022 - Paper 1

This adaptation pertains to the internal mechanisms that allow organisms to survive in harsh environmental conditions. Specifically, in the case of desert mammals that obtain water from breaking down stored body fat, this represents a physiological adaptation.

Physiological adaptations involve changes in an organism's metabolic processes. In these mammals, catabolizing fat stores allows them to derive water, which is crucial for their survival in arid environments. This process underscores the efficiency of metabolic pathways that are crucial for maintaining hydration in scarce water conditions.
