Most of the photosynthetic organisms are located in the epipelagic zone of the oceans where sunlight can penetrate before diffusing and becoming too weak to support photosynthesis. The epipelagic zone is filled with plankton. When this plantkon die, they begin to sink slowly to the bottom of the ocean. These plankton are food for small fish. These small fish are food for bigger fishes. This is how an ecosystem is sustained in the deep dark oceans.
Answer:
1,35 * 10 ^ -2 M
Explanation:
Recuerde que pH = -log [H ^ +]
Sea la concentración de iones de hidrógeno [H ^ +]
Si es así, entonces;
-pH = log [H ^ +]
Por lo tanto;
[H ^ +] = Antilog (-pH)
[H ^ +] = Antilog (-1,87)
[H ^ +] = 1,35 * 10 ^ -2 M
Answer:
Human activities that relate and contribute to desertification include use and expansion of agricultural lands, poor irrigation practices, and deforestation. These land uses place enormous pressure on the land because it alters its soil chemistry.
