Verified step by step guidance
1
Step 1: Understand the domain Eukarya, which includes organisms with complex cells containing a nucleus, such as fungi, plants, animals, and protists.
Step 2: Recognize that fungi are a distinct group within Eukarya characterized by their mode of nutrition, which is heterotrophic absorption, meaning they absorb nutrients from organic material.
Step 3: Identify common food sources derived from fungi, which include mushrooms (the fruiting bodies of certain fungi) and yeast (unicellular fungi used in baking and fermentation).
Step 4: Compare the options given: seaweed and kelp are types of algae (protists), apples and wheat are plants, and E. coli and Lactobacillus are bacteria, so these are not fungi.
Step 5: Conclude that the pair 'mushrooms and yeast' correctly identifies two common food sources that are fungi within the domain Eukarya.
