Which statement about fungal nutrition is not true?
Correct answer: C. Facultative parasitic fungi are host specific
- A. Some fungi are active predators
- B. Some fungi are mutualists
- C. Facultative parasitic fungi are host specific
- D. All fungi require mineral nutrients
Explanation
The correct answer is Option C: Facultative parasitic fungi are host specific. This statement is not true because facultative parasitic fungi can survive and reproduce on multiple hosts or substrates, not limited to a specific one. In contrast, obligate parasites are often host specific, requiring a specific host to complete their life cycle. Let's examine why the other options are true:Option A: Some fungi are indeed active predators, utilizing mechanisms like constricting rings to capture prey such as nematodes.Option B: Many fungi engage in mutualistic relationships, such as lichens (a symbiosis between fungi and algae) and mycorrhizal associations with plant roots, providing mutual benefits.Option D: All fungi require mineral nutrients, as they are essential for growth and metabolic processes, similar to all living organisms.
