A sponge is a colony of cells because it is a group of cells living and working together. It would be a multicellular organism only if those cells were grouped together as a function
The term "multicellular" is a descriptive term used to refer to organisms composed of more than one cell. It is not a scientific name but rather a general classification based on the structure of the organism.
Specialized cells allow for division of labor within the organism, leading to increased efficiency and functionality. They also enable multicellular organisms to perform complex functions and adapt to diverse environments.
A specialized cell means simply that: it has a specific job in the body. Therefore, specialized cells will contain more of the parts it needs to carry out the specialized task. A unicellular organism has only one cell, which means that it has to carry out all functions of life in a single cell. Thus, it will have all the needed parts rather than specialized parts.
No, the cells are not obligate dependents-they can operate independently; the protoplasms of thecells are not connected; the aggregation of cells can be broken into individual cells without killingthe cells.
A campfire is not considered alive because it does not possess the characteristics of life, such as the ability to grow, reproduce, respond to stimuli, or maintain homeostasis. It is a chemical reaction involving fuel, heat, and oxygen, rather than a living organism with cells and biological processes.
No. That suggests something rather complicated (and multicellular) for a one celled organism.

A man o' war is a colony of specialized organisms rather than a single organism, so it does not reproduce sexually like an individual organism would. Instead, new individuals are created within the colony through a process of budding.
No, protozoa are single-celled organisms that exist independently as individuals rather than forming multicellular colonies. They are part of the protist kingdom and exhibit a diverse range of structures and behaviors as single-celled organisms.
Volvox is considered a protist because it is a colony of individual cells working together as a single organism. Each cell within the colony retains its own identity and functions, unlike in metazoan animals where cells are specialized and cannot survive independently. Additionally, Volvox lacks the complex tissue organization and body plan characteristic of metazoans.
Cells that are part of a multi-cellular organism typically have the same metabolic functions as single-celled organisms, however differences exist. Multicellular cells will have a specialized function, typically do not have to independently gather food and will express target genes selectively rather than all of the genes necessary for survival that a single-celled organism might express.
An organism that uses rather than produces is called a comsumer

1. Any kind of abstract (rather than concrete) thinking. Single-celled organisms are apparently somehow aware of their immediate chemical environment (and will move away from toxic molecules, towards nutrient molecules [food], etc.), but that is all. 2. Specialized cells. Not every cell has to carry out every metabolic function in a multicellular organism.

This would be considered a trace fossil, specifically a "ichnofossil" which is a fossilized footprint, burrow, or other trace left by an organism rather than the remains of the organism itself.
