There are trillions of cells EVERYWHERE including blood cells, brain cells, and even skin cells !! I believe that multicellular organisms that are large need to have trillions of cells to be able to fill their whole body. For example , humans, Humans have one of the most complex cells, we humans are very big so thousands of cells would not be enough to contain our entire body. Even the word ' multicellular' meaning multiple cells gives people a hint that we are multicellular . In conclusion , trillions of cells are needed for multicellular organisms , without them we wouldn't be able to function properly.
Answer:
The decomposer has recycled the organic materials in the leaf and released them back into the soil.
Explanation:
Decomposers are the heterotrophic microbes that derive their nutrition by digesting the dead organic matter present in the dead bodies of living beings such as fallen leaves. As a leaf falls from a plant on the land, decomposers present in the soil start its digestion.
The organic and inorganic nutrients present in the leaves are digested into the simpler substances which in turn are released back into the soil. Therefore, decomposers serve in nutrient cycling by releasing substances such as carbon, nitrogen, phosphorus, and sulfur from the dead bodies of living beings back into nature to allow their reuse.
