Since there are chemical and physical digestion types, the digestive system enables the animal to be adaptive and take in other forms of food than it is used to.
No, muticellular.
A sea star is multicellular.
multicellular, all animals are
More complex organisms including plants and animals are called multicellular organisms. These organisms are made up of different types of specialized cells that work together to form tissues, organs, and organ systems.
Adaptive systems are ones that are continually changing to meet the demands of the environment. Non-adaptive systems do not change.
to maintain proper metabolism, mainly gas exchange

Multicellular fungi are different from other multicellular organisms because they lack complex tissues, organs, and systems found in organisms like plants and animals. Fungi obtain nutrients through absorption rather than through photosynthesis or ingestion. Additionally, fungi have a unique cell wall made of chitin, while plants have cell walls made of cellulose.

No, not all multicellular organisms have skeletal systems. While many animals, such as vertebrates, possess internal or external skeletons for support and protection, other multicellular organisms, like jellyfish or sponges, lack a skeletal structure. Instead, they rely on other means, such as hydrostatic pressure or a soft body structure, for support and movement. In summary, skeletal systems are not a universal feature among multicellular organisms.
Rotifers are smaller than protist but nevertheless are multicellular and have speicalized organ systems.
Complex adaptive systems are systems that change and restructure themselves based on changes in their environment. These types of systems can range from ant colonies to global economy investments. Perhaps one of the best examples of complex adaptive systems is the internet.
