Question

the process where plants and animals take nitrogen in and use it to build their own tissues is called? leaching nitrogen fixation assimilation denitrification eutrophication nitrification rewatch

Explanation:

Leaching is the loss of water - soluble plant nutrients from the soil. Nitrogen fixation is the conversion of atmospheric nitrogen (\(N_2\)) into ammonia (\(NH_3\)). Assimilation is the process where plants and animals take up nitrogen compounds (such as nitrates) and use them to build their tissues. Denitrification is the conversion of nitrates (\(NO_3^-\)) into nitrogen gas (\(N_2\)). Eutrophication is the enrichment of a water body with nutrients, leading to excessive plant growth. Nitrification is the conversion of ammonia (\(NH_3\)) to nitrites (\(NO_2^-\)) and then to nitrates (\(NO_3^-\)).

Answer:

Assimilation.
