BRAINLEST SUPER EZ QUESTION Why is ocean water considered a mixture but a cup of water is a pure substance?

Ocean water is a mixture! Salt and water together, makes salt water, since the salt dissolves in it.

Normal water in a cup, though, is a pure substance. Nothing is in it, and its purified, so it is not a mixture.

If it's more than one things, it's a mixture!

I hope this helps!

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
