Question

In which of the following group of organisms, food material is broken down outside the body and absorbed?

• A. Mushroom, green plants, Amoeba
• B. Yeast, Mushroom, bread mould
• C. Parameocium, Amoeba, Cuscata
• D. Cuscuta, lice, tapeworm

Answer 1

The correct option is B

Yeast, Mushroom, bread mould

The correct option is B.

The explanation for the correct option:

• The organisms absorbing the food material that is broken down outside their body are known as saprophytes.
• The food consumed by the saprophytes includes non-living organic material.
• Examples of these organisms include mushrooms, bread moulds, and yeast.

The explanation for incorrect options:

Option A:

• The green plants are involved in the organisms that can create their food (autotrophs), while amoeba can ingest and then digests their food.

Option C:

• Paramoecium and Ameoba digest their food after consumption, while Cuscata gets its food from other plants by growing on them.

Option D:

• The organisms like Cuscata, tapeworm, and lice receive their food from other organisms through parasitic activity.

Therefore, the organisms that absorb the food material, which is broken down outside their body, include yeast, mushroom, and bread mold.
