Unformatted text preview: their nitrogen from herbivores Waste, dead plants, and animals; nitrogen in them is modified by bacteria and fungi, they convert waste products in to ammonia compounds, ammonia compounds can be taken up by plants, more bacteria convert ammonia compounds into nitrite, other bacteria converting nitrite into nitrate, which can be taken up by plants. Plants can get nitrogen from atmosphere indirectly; during a storm some nitrogen in the air can be converted into ammonia compounds (nitrogen fixation) and the plant can absorb it.
