Final answer:
Trout are adapted to live in cool mountain streams and cannot tolerate the warm habitats that carp and catfish can. This distinction is based on the different temperature preferences and ecological adaptations of these fish species.
Step-by-step explanation:
Trout live only in cool mountain streams and do not inhabit the warm habitats tolerated by carp and catfish. This is reflective of the varying ecological niches and temperature preferences that different fish species have.
Trout, which are cold-water species, have adapted to thrive in cooler waters and are often found in habitats with consistent lower temperatures and high oxygen levels, making them sensitive to changes in temperature and water quality. On the other hand, carp and catfish are more adaptable to a range of temperatures, including warmer waters, and can often be found in habitats with varying levels of human disturbance.
