Animals, plants, fungi, and protists
Explanation:
Animals, plants, fungi, and protists are examples of Eukaryota organisms. Animal and plant cells contain many of the same kinds or organelles. There are also certain organelles found in plant cells that are not found in animal cells and vice versa.
In order for plants to assimilate nitrogen directly into their system, the nitrogen must be in the form of nitrates. Nitrogen in the air and ammonia from decayed matter in the soil is converted to ammonium by decomposers and nitrogen-fixing bacteria. The ammonium is further nitrified to nitrates by nitrifying bacteria. Finally, the nitrates can then absorbed by the plants.
