Which of the following can survive in extreme environments (like high temperature or acidity)

you didn't put the answer choices but I'm sure if it's a species that is considered an extremophile such as the tartagrade (water bears) then those will be your answers.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
