Answer:
This is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems:
1. Phosphorus is highly stable in the atmosphere and remains there for long periods of time.
Explanation:
The phosphorus first cycle is the process by which the phosphate ion passes in very small amounts through the lithosphere from volcanic aeorosols, then to the hydrosphere, where it stays from 20,000 to 100,000 years in the ocean, and finally to biospherere, where rain and erosion helps washing the phosphorus from the rocks into the soil. So, raining is the beginning of the phosphorus´s second cycle, so it is also, the slowest one of the matter cycles that is why the natural total background phosphate levels in several bodies of freshwater range from 0.005 to 0.05 mg/L. Phosphorus remains mostly on land and in rock and soil minerals.
Although abundant on our planet´s sedimentary rock crust and in human body, phosphorus to commercialize is only found in minerals therefore, phosphates mining activity and calcium heating is the only way to get it in its pure elemental form. It is an essential nutrient for plants and animals and a big percentage of the mined phosphorus is used to make fertilizers.
Answer:
Based on the solar light that enters the oceans and river
Explanation:
- River ecosystem of a couple of both biotic and abiotic components among the plants and animals involving there physical and chemical properties. As the flow of water is unidirectional, it's in state of continuous physical change and has a high degree of spatial and temporal heterogeneity.
- River sources are small, and in the areas of mountain streams, are steep and erosional. In temperate environments, overhead tree canopy conditions result in cool, well-oxygenated streams.
- All sorts of communities like coastal, estuaries, reefs and deep-sea trenches like Mariana trench which has no sunlight has a distinct type of community.
The light spreads on the earth unevenly due to It's tilt. The position
of the earth changes in orbit, and the earth either becomes tilted
towards or away from the sun. This is why seasons happen.
When tectonic plates move or when they rubbed with each other earthquake happens
Answer:
The biome receives the greatest amount of solar energy during the spring
and summer months
Explanation:
A biome may be defined as that community of plants as well as animals that have a common characteristics in the surrounding or the environment in which they live. They are the biological communities formed as a result of the physical climate they share.
The Arctic biome of the earth is located above the 66° north latitude. This region is home to various low growing plants and herbs. They only flourish in the spring seasons and the summer months. This is because this biome receives maximum amount of solar energy during the summer and the spring months. Rest of the year is covered with snow.
