The answer is "Decomposers directly convert ammonium into nitrogen gas".
Living organisms such as plants and animals contains nitrogen in the form of the amino acids and proteins. When they die, the nitrogen in the form of ammonium is decomposed by microorganisms. It is then converted into nitrites and then to nitrates by nitrifying bacteria. The denitrifying bacteria then converts nitrates into nitrogen.
Answer: The advantages of spines in these unrelated organisms are as follows:
- for escape and defence
- for regulations of body temperature
- for conservation of water
Explanation:
The evolution of spines in Tenrecs, echidnas and hedgehogs represent STRUCTURAL ADAPTATION i.e when a part of the body of a living organism undergoes changes to become structurally adapted to its mode of life.
- The evolved spines in hedgehogs are for physical defence
- in tenrecs, they are for physical defense
