Very few living things survive below which temperature, because of metabolic constraints?

1. Temperature exerts an important influence on living things. 2. Few living things can survive at temperatures below 0 degrees Celsius due to metabolic constraints. 3. Therefore organisms must either maintain an internal temperature or inhabit an environment that keeps the body in a workable range. 4. 4 degrees Celsius is where water is densest, which is a different fact. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 35 'Ecology and the Biosphere', sections 35.1-35.5_
