Which set contains only kingdoms that include autotrophs?

• A. Fungi, Bacteria, Animalia
• B. Animalia, Protista, Fungi
• C. Plantae, Protista, Bacteria
• D. Fungi, Animalia, Plantae

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the term 'autotrophs.' Autotrophs are organisms that can produce their own food using light (photosynthesis) or chemical energy (chemosynthesis). Examples include plants, algae, and certain bacteria.
2. Step 2: Analyze the kingdoms listed in the problem. Recall that Plantae, Protista, and Bacteria include autotrophs. Plantae consists of plants that perform photosynthesis, Protista includes algae that are autotrophic, and Bacteria includes cyanobacteria that are autotrophic.
3. Step 3: Evaluate the other kingdoms mentioned. Fungi are heterotrophs that obtain nutrients by decomposing organic matter. Animalia consists of heterotrophs that consume other organisms for energy. Neither kingdom includes autotrophs.
4. Step 4: Compare the sets provided in the problem. Identify which set exclusively contains kingdoms known to include autotrophs. The correct set is 'Plantae, Protista, Bacteria.'
5. Step 5: Confirm your understanding by reviewing the characteristics of each kingdom and ensuring that the correct set aligns with the definition of autotrophs.
