Bacteria that grow optimally at 25-40oC are called as
**Core Concept**
Bacteria that grow optimally at specific temperature ranges are classified based on their thermophilic properties. This classification helps in understanding their ecological niches and potential applications in various fields.
**Why the Correct Answer is Right**
Bacteria that grow optimally at 25-40°C are mesophiles. These organisms thrive in moderate temperatures, typically found in environments such as soil, water, and the human body. Mesophiles have optimal growth temperatures between 25°C and 40°C, making them well-suited for growth in temperate climates.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it doesn't specify a valid temperature range for any particular group of bacteria.
**Option B:** This option is incorrect as psychrophiles grow optimally at temperatures below 20°C, not within the 25-40°C range.
**Option C:** This option is incorrect as thermophiles grow optimally at temperatures above 40°C, not within the 25-40°C range.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that temperature range is a critical factor in classifying bacteria, as it affects their growth, metabolism, and potential pathogenicity.
**Correct Answer: C. Thermophiles**
