The correct answer to the question is releasing waste and decomposition. In the nitrogen cycle, once a consumer gains nitrogen nutrients from animals or plants, it recycles these nutrients back to the earth by releasing waste and decomposition.
Answer:
The correct answer is - microevolution.
Explanation:
Microevolution is the very small evolutionary change specially allele frequencies on the level of species that occurs slowly over period of time. These changes occurs on the level of DNA or genetic level.
These evolution can be caused by the natural selection process or genetic drift over the generation of the species or population over period of the time. It is the study of the evolution that occurred on level of separated gene pool.
Thus, the correct answer is- microevolution.
Answer:
The correct answer is A. Fossil fuels are cheaper than alternative forms of energy
Explanation:
Fossil fuels are made from organic matter of dead animals and mainly plants who were buried in the soil over hundred and thousand of years. We use fossil fuels because they are the best source to provide energy in the current time.
Fossil fuels are easily available and are present in very large amount which is the main reason for it to be cheaper. Fossil fuels like coal, petroleum or natural gas are more cheaper and efficient than alternative forms of energy like solar or wind energy.
But in future these fossil fuel will not be there and alternative forms of energy will become the primary and cheaper source of fuel.
