In which of the following groups of organisms, food material is broken down outside the body and absorbed ?Green plants, Rat, AmoebaRat, Ticks, MushroomYeast, Bread moulds, MushroomAmoeba, Mushroom, Tapeworm

The group of organisms in which food material is broken down outside the body and absorbed is "Yeast, Bread moulds, Mushroom".

Here's why:

1. Green plants, Rat, Amoeba: Green plants make their own food through photosynthesis, rats digest their food internally, and amoebas engulf their food and then digest it internally.

2. Rat, Ticks, Mushroom: Rats and ticks digest their food internally. Mushrooms do break down food externally and then absorb it, but not all organisms in this group follow this pattern.

3. Yeast, Bread moulds, Mushroom: All these organisms are types of fungi. Fungi secrete enzymes that break down complex organic material in their environment into simpler substances, which they then absorb. This is a form of external digestion.

4. Amoeba, Mushroom, Tapeworm: Amoebas and tapeworms digest their food internally. Only mushrooms in this group break down food externally and then absorb it.
