Question

Which of the following organisms is a multi-celled producer?

1) an oak tree
2) Candida, a pathogenic fungus
3) E. coli, a common intestinal bacterium
4) a Siberian tiger
5) more than one of these

Answer 1

An oak tree is a multicellular producer that can perform photosynthesis, unlike yeasts, molds, E. coli bacterium, and Siberian tiger. Hence the correct answer to the question is option 1) an oak tree.

Step-by-step explanation:

The question is asking to identify a multicellular producer from the options provided. Producers are organisms that can make their own food typically through photosynthesis, and therefore must be able to harness energy from the sun. Taking into consideration the information about fungi and other organisms provided, we know that fungi, including Candida, commonly known as yeasts, and molds are not producers as they do not perform photosynthesis but rather break down organic material and are thus consumers or decomposers. The E. coli bacterium is also not a producer; it is a unicellular organism living in the intestines of animals and humans. The Siberian tiger is a consumer, specifically a carnivore, and is also not a producer. The remaining option is an oak tree, which is a multicellular organism that performs photosynthesis making it a producer. Therefore, the correct answer is 1) an oak tree.
