👉 Heterotemps, also known as non-thermophilic organisms, are found in cold environments where temperatures are below freezing or even zero degrees Celsius. These organisms lack enzymes that would help them digest food and metabolize energy efficiently, making it difficult for them to survive. Heterotemps primarily inhabit cold deserts, such as the Mojave Desert in the United States, where temperatures can reach -100°F (-37°C).
