A cell. Cells are the basic unit of life. Unicellular organisms can perform life tasks on its own, and they are one cell. Multicellular organisims have more than one cell (you and I), and can also perform life tasks.

Yes, that is true.

heterotrophs
Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis, while heterotrophs rely on consuming other organisms for their food. Autotrophs are primary producers in the food chain, while heterotrophs are consumers that obtain energy by breaking down organic matter. Autotrophs play a crucial role in producing energy for ecosystems, while heterotrophs consume this energy to sustain themselves.
Unicellular organisims are organisims that only have one cell like a zebra only has one cell.
Heterotrophs must 'eat' other organisims in order to survive and make ATP, while autotrophs (such as plants) make their own food from the air
One good reason for that would be that O2 levels, the product of autotrophs, was not high in the early atmosphere. So, you needed autotrophs to build that O2 level to an appreciable amount of oxygen in the air. Since there was anaerobic life before autotrophs one could be reasonable sure they were hetertrophic.
A unicellular organism is a life form consisting of a single cell.
Organisims that make its own food is called a AUTOTROPH for example PLANT
protista, e.g phycomycetes , myxomycetes , which are unicellular but have complex cellular structure i-e have a true nucleus.
autotroph is any animal that makes its own food, as opposed to heterotrophs that rely on other organisims for food
No group of animals make their own food. Only plants and some bacteria do.
Multicellular organisms are made up of specialized cells that work together to form tissues and organs, while colonies of unicellular organisms consist of individual cells living in close proximity but maintaining their independence. Multicellular organisms have a higher level of organization and coordination compared to colonies of unicellular organisms.
I would ask Google. Better answer: you, a dog, a horse, a bird, and many other and mostley all other animals are heterotrophs because they rely on other organisims to have their source of food and nutrition
