Why The Main Nitrogenous Excretory Product Of Humans Is Urea Rather Than Ammonia? Urea is less toxic and requires less water to remove from organism (so it’s better in terrestrial environment) but it requires more energy to produce. And uric acid is most costly in terms of energy but requires the least amount of water
What Do Invertebrates Use To Collect And Expel Wastes? This is not to say, however, that each invertebrate phylum has evolved its own particular type of excretory organ; rather, there appear to be five main types of invertebrate excretory organ: contractile vacuole, nephridium What type of waste do invertebrates excrete? Invertebrates employ a variety of
How Consumer Are Involved In The Nitrogen Cycle? What do consumers do in the nitrogen cycle? Once the plants use the nitrates, consumers eat the plants so the nitrogen is transferred. The consumers die and give off wastes transferring the nitrates back to the environment. Other bacteria unfix the nitrates, or change it back into
How Is Nitrogen In The Atmosphere Cycled Back Into Organism? Nitrogen gas from the atmosphere is fixed into organic nitrogen by nitrogen-fixing bacteria. This organic nitrogen enters terrestrial food webs. It leaves the food webs as nitrogenous wastes in the soil. How is nitrogen cycled? Nitrogen Cycle is a biogeochemical process through which nitrogen is
