Question

Which of the following feed upon dead plant and animal tissues?

• A. Spirogyra
• B. Mushroom
• C. Chlamydomonas
• D. Chlorella

Answer 1

The correct option is B Mushroom

Spirogyra contains chlorophyll and obtains nutrition through the process of photosynthesis.

Chlamydomonas in the similar way, has photosynthetic mode of nutrition and it makes its own food by the process of photosynthesis.

Mushrooms are included in Kingdom fungi. They have no chlorophyll of their own. So they cannot perform the process of photosynthesis. As a result, they possess saprophytic mode of nutrition. this means that they derive nutrition from decaying dead plants and animals. They convert the complex organic substances in their body to simple inorganic substances and thus obtain the necessary nutrition.

So, option B "Mushroom' is the correct answer.
