Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?
In single-celled organisms the entire surface of the organisms is in contact with the environments for the diffusion of substances. In multi-cellular organisms all the cells may not be in direct contact with the surrounding environment. So simple diffusion will not meet the requirements of all the cells.

Marine biological factors?
Biological factors, an part of the marine environment influenced by organisms and which influences other organisms, include diffusion osmosis, active transport, and cellular surface-to-volume ratio.
What role does diffusion play in cellular respiration?
well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis
Are humans cellular organisms?
Yes, humans are cellular organisms. Specifically, we are multi-cellular organisms, consisting of millions and millions of cells.
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.
Describe methods by which substances enter and leave cells that require cellular energy?
Diffusion is the methods that leave cells. Diffusion also has to have cellular energy.
Organisms remove metabolic cellular wastes by the process of what?
Organisms remove metabolic cellular wastes by the process of excretion.
What organisms do cellular respiration?
All organisms
What cellular process does not require ATP?
Diffusion and Osmosis.... I think. It would be better to double check ;)
How does water enter or leave the uni cellular organism by diffusion or osmosis?
osmosis is a form of diffusion. in regard to water, the diffusion type would be osmosis
