As weeds’ roots die, they, along with weeds’ dead leaves and stems, decompose to enrich the ground with humus. Weeds probably correct mineral imbalances in the soil. Contrast the diversity of plants in an uncultivated field with the uniformity of plants in a weed-free cornfield. In the ...
Rotting starts after the death of a whale, as the insides begin to decompose. The whale then expands and floats up to the ocean's surface, where it can be scavenged by sharks and seabirds. Eventually, the carcass will begin to sink, falling kilometer after kilometer, until finally coming ...

The importance of leaves When the leaves begin to die in fall, they turn from green to yellow and fall from the trees. As they decompose on the ground, nutrients(营养物质) are returned to the soil and carbon dioxide to the air. Life in the forest needs these nutrients. Without them, ...

instance, soil that has a pH of 7.0 or above is not adequate for plants that require an acid soil. Adding fresh oak leaves to the broken soil may satisfy the plants for a short while, but over time the plants will fail to thrive as the oak leaves begin to decompose and the soil pH...
Hint:Diatoms area major group of algae(microalgae). Diatoms are unicellular organisms; they occur either individually as solitary or in colonies. Complete answer: Diatoms are eukaryotic organism. ... When these diatoms die and decompose, the silica returns back to the earth surface in the form ...
they carry in their bodies countless nutrients accumulated through their lives at sea. When spawning salmon die, their bodies decompose in the riverbeds, filling the local soil with ocean-derived nutrients that they could not access any other way. Maintaining a healthy redwood population requires a...
the microorganisms give off carbon dioxide and heat. Temperatures within a compost pile can rise as high as100 to 150 degrees Fahrenheit(38 to 66 degrees Celsius). If you manage your compost pile by turning and watering it regularly, it will decompose into finished compost withina few weeks....
