Why multicellular organisms need special organs for exchange of gases between their body and their environment?

Our body is made up of prokaryotic cells. These cells are not in the contact with the environment. So the process of diffussion cant make any difference in exchange of gasses between the multicellular boy and environment.

Why must complex muticellular organisms have transport systems?
Large organisms need transport systems to supply all their cells with food, oxygen and other materials.Multi-cellular organisms are too big and not all of their cells have contact with the external environment. All organisms need to exchange substances with their environment - take in needed molecules and get rid of waste. A uni-cellular organism can use the processes of osmosis, diffusion and active transport to transport substances in and out of the organism, which is in this case just one cell. But as organisms increase in size, they need a specialized transport system to exchange substances between the internal environment and the external environment. Interestingly enough, osmosis and diffusion are still the important mechanisms at the cellular level.
What comes between first eukaryotes and first terrestrial eukaryotes on a timeline?
evolution of first multicellular organisms
The study of interaction between organisms and their environment?
Ecology
3 Differences between unicellular and multicellular organisms?
Three differences between unicellular and multicellular organisms is that unicellular organisms are microscopic and can live in extreme temperatures. Multicellular organisms are much larger and have systems and organs.
Why are colonial organisms not multicellular?
Colonial organisms have some of the same characteristics of multicellular organisms. The difference between a multicellular organism and a colonial organism is that individual organisms from a colony can survive on their own, while cells from a multicellular organism cannot.
The exchange of useful chemicals between organisms and their abiotic environment is an example of?
a material cycle
Distinguish between multicellular organisms and colonies of unicellular organisms?
protists, plants, animals, and fung.
The relationship between living organisms in the aquatic environment?

What is the exchange of useful chemicals between organisms and their abiotic environment an example of?
A symbiotic relationship occurs when both parties benefit from the exchange. This does occur when organisms in the soil exchange minerals for food from plants and they will help protect the plant from attack so they should be encouraged.
Describe how nutrients are passed between organisms and the environment?
passed between organisms and teh environment through biogeochemical cycles
What are the similiarities between panda and mushroom?
Pandas and mushrooms are both examples of multicellular organisms.
What is a term for the study of the relationship between organisms and their environment?
The study of the relationship of organisms and their environment is called ecology.
What the study of the relationship between organisms and their environment?
Ecology is the study of interactions between organisms and their environment. THis includes interactions organisms have with each other, as well as their abiotic environment. Ecologists often cover diversity, distribution, population of organisms, as well as the competition between them and among ecosystems.
What is the difference between a human cell and a escherichia coli cells?
cells of a multicellular organisms are specialized
