Which of these is an disadvantage of multicellular organisms?

Multicellular organisms require a lot of energy and resources to survive.

Unicellular organisms, on the other hand, require just the basic necessities. On top of that, unicellular organisms don't require a long time to reproduce as multicellular organisms do.

Thus, multicellular organisms are at a disadvantage because they require more energy, sources, and essentially time.

Hope this helps!
