A group which shows heterotrophic mode of nutrition isa)Algaeb)Fungic)Bryophytesd)NoneCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Plants and animals differ in the mode of nutrition. Based on the process of obtaining food, the modes of nutrition can either be autrophic or heterotrophic.

Heterotroph is a word derived from two Greek words heteros (other) and trophe (nutrition). Heterotrophic nutrition therefore, refers to that mode of nutrition, where organisms that lack chlorophyll cannot create their own food through photosynthesis and depend on others for their food. This process helps organism such as animals, fungi, and prokaryotes obtain nutrition by digesting organic compounds.

Based on the mode of living and intake of food, heterotrophic nutrition can either be parasitic, saprophytic and symbiotic.

Thus, the correct answer is option B.

Answer

Understanding Heterotrophic Nutrition
Heterotrophic nutrition is the mode of nutrition where organisms cannot synthesize their own food and rely on other organisms for sustenance. This is primarily seen in fungi, animals, and some other organisms.
Why Fungi Show Heterotrophic Nutrition
- Absorptive Nutrition: Fungi absorb nutrients from their surroundings. They secrete enzymes that break down complex organic materials into simpler compounds, which they then absorb.
- Decomposers: Many fungi act as decomposers, breaking down dead organic matter, recycling nutrients back into the ecosystem.
- Symbiotic Relationships: Some fungi form mutualistic relationships, such as mycorrhizae with plant roots, where they help plants absorb water and nutrients in exchange for carbohydrates.
Contrast with Other Options
- Algae: Algae are primarily autotrophic as they contain chlorophyll and can perform photosynthesis to produce their own food.
- Bryophytes: Although bryophytes (like mosses) are more complex than algae, they primarily engage in photosynthesis for energy, thus classifying them as autotrophic.
- None: This option does not apply as fungi distinctly represent heterotrophic organisms.
Conclusion
Fungi are the correct answer to the question of which group demonstrates a heterotrophic mode of nutrition due to their unique ability to absorb nutrients from their environment, making them essential decomposers in ecosystems.
