Match the following terms and their definitions. 1. hypothesis an assumed explanation for a problem 2. law supported by evidence gathered over a period of time 3. theory an absolute fact or truth about a specific phenomenon

The correct answer is-

Term 1 matches with an assumed explanation for a problem.

Term 2 matches with an absolute fact or truth about a specific phenomenon.

Term 3 matches supported by evidence gathered over a period of time.  

Explanation:

A hypothesis is the presumed or a scientific guess explanation for a particular problem. It should be based on prior scientific knowledge about the problem and can be tested to test it.

Law is the universally accepted fact or truth about any specific phenomenon. It should be the same at any time under the same condition and provide same results.

The theory is an explanation that is supported by the different pieces of evidence and well substantial knowledge over a period of time.

Thus, the correct answer is -Term 1 matches with an assumed explanation for a problem.

Term 2 matches with absolute truth or fact about a specific phenomenon.

Term 3 matches with supported by evidence gathered over a period of time.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
