According to the material, life on Earth can survive under which range of environmental conditions?

• A. A wide range of environmental conditions
• B. Only under very specific conditions
• C. Only in extreme heat
• D. Only in stable climates

Answer: (A)

Life on Earth can endure a wide spectrum of environmental conditions because living organisms have evolved to tolerate and exploit many different habitats. The material emphasizes how life ranges from microbes that can survive extreme desiccation, vacuum, and high temperatures to plants and animals that thrive in deserts, oceans, and polar regions. This broad adaptability shows that survival is not limited to a single set of conditions but spans a wide range of temperatures, pH, salinity, radiation, and nutrient availability. The idea is that Earth's biosphere is incredibly diverse, with many organisms adapted to very different environments, which supports the choice that life can survive under a wide range of environmental conditions. The other options suggest narrowly defined conditions—only under very specific conditions, only in extreme heat, or only in stable climates—yet the material demonstrates that life persists across many and varied environments.
