The energy came from the sun.
The sun increase the temperature on every water surface on the earth which make it transform from liquid to gas, and eventually from cloud.
When the clound condensed, it will fall on top of the geological surface in the form of rain and some of it will fallen to the river and eventually came back to the sea to complete the cycle.
They are both <span>multi-cellular, autotrophs, and in the Plants kingdom.</span>
Answer:
Genetic analysis, structure analysis and study the behaviour.
Explanation:
Genetic analysis, structure analysis and study the behaviour of organisms are the observations or tests that would make it possible to determine whether it is a protozoan, fungus, or algae because these analysis provides information about the genetic makeup and structure of their cell. If the cell wall is made of chitin then it is considered as fungi, if the cell wall is made of peptidoglycan then it is an algae and if the cell wall is not present then it is considered as animals like protist.
