The incorrect statement about the nitrogen cycle is option A: nitrate and nitrite reductases in denitrifying bacteria convert ammonia to nitrogen gas.
The biological nitrogen fixation (BNF) is the process by which atmospheric nitrogen is changed into ammonia, and the nitrogen-fixing bacteria are known as diazotrophs. Fixation, ammonification, nitrification, and denitrification are significant nitrogen cycle processes. Ammonia is converted to nitrites and then to nitrates which are absorbed by plants with the help of their roots. Therefore, option A is incorrect.
Through bacteria that fix nitrogen from the atmosphere, nitrogen enters the living world. Soil bacteria convert this nitrogen and nitrogenous animal waste back into gaseous nitrogen, supplying the organic nitrogen required by terrestrial food webs.

Answer: Digestive system
Explanation:
Fat carries out many functions in the body of organisms. They are great source of energy especially when less amount of glucose is present in the body. They act as pads to many structures in the body.
Their roles in adding flavor to food is highly emphasized and their vehicular role in moving food in the gut have helped greatly in acquisition of nutrients by organisms
Graduating from high school this year makes me feel a bit sad. Biology was such a fun but crazy class.
Enough of my sentiments; I'm here to help, :-).
This answer is dependent upon what ecosystem you choose your project over.
So, abiotic factors are nonliving things in an ecosystem. Biotic factors are living organisms and anything alive.
For instance, if you choose a pond for your ecosystem then the water, soil, maybe trash would be abiotic factors. Some could argue there is living material within the water and soil but those abiotic factors are not alive. I mean water is not alive but it could be a home to biotic factors like microorganisms such as protozoans and worms. The grass and trees and animals around a pond would be biotic factors.
Hope you get the idea. if there's any questions then leave a comment and I'll help. Good luck!
