What are the classifications of bacteria based on temperature preferences?

Bacteria are classified based on their temperature preferences into three main categories: psychrophilic, mesophilic, and thermophilic.

Psychrophilic bacteria thrive in cold environments, typically within a temperature range of 0°C to 20°C (32°F to 68°F). These organisms are often found in places such as Arctic and Antarctic regions, as well as in deep ocean waters. Their adaptations allow them to function optimally at these lower temperatures.

Mesophilic bacteria prefer moderate temperature ranges, generally between 20°C to 45°C (68°F to 113°F). This category includes many bacteria that are significant in human agriculture, food production, and even in the human body, as they grow best in the temperatures typically found in these environments, such as in compost or sewage treatment processes.

Thermophilic bacteria, on the other hand, thrive in high-temperature environments, usually around 45°C to 80°C (113°F to 176°F) or even higher. These bacteria are often found in hot springs, geothermal vents, or within compost that is actively decomposing organic material. Their ability to withstand and flourish at elevated temperatures is due to specialized proteins and enzymes.

The correct option precisely describes these classifications, reflecting
