Question

All fungi are:

• A. Parasites
• B. Heterotrophs
• C. Autotrophs
• D. Saprophytes

Answer 1

The correct option is B

Heterotrophs

The correct option is B.

Explanation of the correct option:

1. Organisms that are dependent on other organisms for their food are referred to as heterotrophs.
2. Fungi cannot perform photosynthesis and thus cannot make their own food.
3. Thus, fungi are heterotrophs.

Explanation of the incorrect options:

Option A:

1. Parasites are organisms that live on a host and derive nutrition from them.
2. Not all fungi are parasitic.
3. Some Deuteromycetes are not parasitic.

Option C:

1. Autotrophs are organisms that produce their own food and aren't dependent on others for nutrition.
2. Fungi do not possess chloroplasts for photosynthesis and thus aren't autotrophic.

Option D:

1. Saprophytes are organisms that absorb soluble organic matter from dead organisms.
2. While most fungi are saprophytic, not all fungi are saprophytes.

Final answer: All fungi are Heterotrophs.
