Question

In which group of the organism listed below food material is broken down outside the body and absorbed ?
a) Tapeworm, Amoeba, Paramecium
b) Cuscuta, Mosquito, Tapeworm

c) Rhizopus, Mushroom, Yeast
d) Mushroom, Rhizopus, Green plants
Correct answer is option 'C'. Can you explain this answer?

Answer

Rhizopus,Mushroom,yeast are all saphrophytic plants.They feed on dead and decaying organic matter.They break the food outside the body and then absorb the food.

Answer

(C) is the correct answer because Rhizopus, Mushroom, Yeast and Bread moulds are saprophytes and break down the food material outside their body.

Answer

This type of nutrition is known as saphrotropic mode of nutrition and this mostly occur in fungi. rhizopus, mushroom and green plants are saprophytic. So, correct answer is 'd' option

Answer

Answer:

Introduction:
In order to understand which group of organisms breaks down food material outside the body and absorbs it, we need to examine the listed organisms and their feeding mechanisms.

Analysis of the Organisms:
Let's analyze the different groups of organisms mentioned in the options and their feeding mechanisms:

a) Tapeworm, Amoeba, Paramecium:
- Tapeworm: Tapeworms are parasitic organisms that live in the intestines of vertebrates. They absorb nutrients directly from the host's gut and do not break down food material outside the body.
- Amoeba: Amoebas are unicellular organisms that engulf food particles through a process called phagocytosis. They form pseudopods to surround and engulf food, which is then broken down inside their cell.
- Paramecium: Paramecia are ciliated protists that sweep food particles into a specialized oral groove and into a food vacuole. The food is then digested inside the vacuole.

b) Cuscuta, Mosquito, Tapeworm:
- Cuscuta: Cuscuta, commonly known as dodder, is a parasitic plant that absorbs nutrients from its host plant. It forms haustoria that penetrate the host plant and absorb nutrients directly.
- Mosquito: Mosquitoes are insects that feed on the blood of hosts. They have specialized mouthparts for piercing the skin of the host and sucking blood.
- Tapeworm: As mentioned earlier, tapeworms absorb nutrients directly from the host's gut and do not break down food material outside the body.

c) Rhizopus, Mushroom, Yeast:
- Rhizopus: Rhizopus is a type of fungus that obtains nutrients through external digestion. It secretes digestive enzymes onto its food source, breaking it down into smaller molecules that can be absorbed.
- Mushroom: Mushrooms are also fungi and obtain nutrients through external digestion. They release digestive enzymes onto their substrate and absorb the broken-down nutrients.
- Yeast: Yeasts are single-celled fungi that obtain nutrients through both external digestion and direct absorption. They secrete enzymes to break down complex molecules and absorb the resulting nutrients.

d) Mushroom, Rhizopus, Green plants:
- Mushroom and Rhizopus: As explained earlier, both mushroom and Rhizopus obtain nutrients through external digestion.
- Green plants: Green plants are autotrophs that can perform photosynthesis to produce their own food. They do not break down food material outside the body.

Conclusion:
From the analysis above, it is clear that the group of organisms in which food material is broken down outside the body and absorbed is option 'C': Rhizopus, Mushroom, Yeast. These organisms are fungi that obtain nutrients through external digestion.
