Question

scientists have discovered organisms that thrive in hot water that is 90°c (194°f) and do not need sunlight or oxygen to live. into which kingdom would the scientists classify the organisms?
fungi
plantae
protista
archaebacteria

Explanation:

• Fungi: Fungi are heterotrophic organisms. They absorb nutrients from organic matter. They do not typically thrive in extremely hot water at \(90^{\circ}C\) without sunlight or oxygen in the way described.
• Plantae: Plants are autotrophic (most use photosynthesis which requires sunlight). They cannot survive in an environment without sunlight (for photosynthesis) and in extremely hot water (\(90^{\circ}C\)) without oxygen as described.
• Protista: Protists have diverse modes of nutrition (autotrophic, heterotrophic). But most protists do not thrive in such extreme high - temperature (\(90^{\circ}C\)), anoxic, and non - photosynthetic environments.
• Archaebacteria: Archaebacteria are known for their ability to live in extreme environments. Thermophilic archaebacteria can thrive in hot water (such as \(90^{\circ}C\)). Some archaebacteria are also anaerobic (do not need oxygen) and do not rely on sunlight for energy (they can use chemosynthesis).

Answer:

Archaebacteria
