A) Your teacher describes an organism that digests its food externally before absorbing it. You also find out that this organism cannot move. Based on what you’ve learned, this organism is most likely a(n)
answer choices:
protist.
bacterium.
animal.
fungus.
the answer is A
Based on the given information, the organism that digests its food externally before absorbing it and cannot move is most likely a fungus.
To determine the answer, let's analyze the given information. Your teacher describes an organism that digests its food externally before absorbing it. Additionally, this organism cannot move.
To figure out what kind of organism this might be, we need to understand the characteristics and behaviors of different types of organisms.
A protist is a diverse group of eukaryotic microorganisms that can have various modes of nutrition, including both external digestion (in some cases) and internal digestion. However, some protists are capable of movement, which contradicts the fact that this organism cannot move. Hence, we can eliminate protist as the correct answer choice.
Bacteria are a type of prokaryotic microorganism. They can excrete enzymes to break down food externally, but they are most commonly known for their ability to move with the help of flagella or other appendages. Since the given organism cannot move, we can rule out bacterium as the answer.
Animals are multicellular eukaryotic organisms that typically have internal digestion. They often move to find and capture food. Given that this organism cannot move, we can exclude animal as the answer.
Finally, fungi are multicellular eukaryotic organisms that obtain nutrients through external digestion. They secrete enzymes into their surroundings to break down organic matter before absorbing it. Fungi do not have the ability to move, making them a suitable candidate for the given characteristics. Therefore, the correct answer is fungus.
In conclusion, based on the information provided, the organism is most likely a fungus.
