Answer:

First I'd be found in rocks. Erosion would wash me into the soil. Then I'd be absorbed by plants, fungi or microorganisms so they can grow. Animals would get me by eating the plants or drinking the water that eroded the rock. The plants and animals die and I'm absorbed back into the soil.

Explanation:

Phosphorus Cycle Steps

The phosphorus cycle is a slow process, which involves five key steps.

Weathering

Since the main source of phosphorus is found in rocks, the first step of the phosphorus cycle involves the extraction of phosphorus from the rocks by weathering. Weather events, such as rain and other sources of erosion, result in phosphorus being washed into the soil.

Absorption by Plants and Animals

Once in the soil, plants, fungi, and microorganisms are able to absorb phosphorus and grow. In addition, phosphorus can also be washed into the local water systems. Plants can also directly absorb phosphorus from the water and grow. In addition to plants, animals also obtain phosphorus from drinking water and eating plants.

Return to the Environment via Decomposition

When plants and animals die, decomposition results in the return of phosphorus back to the environment via the water or soil.  

Plants and animals in these environments can then use this phosphorus, and step 2 of the cycle is repeated.

Human Impact on the Phosphorus Cycle

Humans have had a significant impact on the phosphorus cycle due to a variety of human activities, such as the use of fertilizer, the distribution of food products, and artificial eutrophication. Fertilizers containing phosphorus add to the phosphorus levels in the soil and are particularly detrimental when such products are washed into local aquatic ecosystems. When phosphorus is added to waters at a rate typically achieved by natural processes, it is referred to as natural eutrophication. A natural supply of phosphorus over time provides nutrients to the water and serves to increase the productivity of that particular ecosystem. However, when foods are shipped from farms to cities, the substantial levels of Phosphorus that is drained into the water systems is called artificial or anthropogenic eutrophication. When levels of phosphorus are too high, the overabundance of plant nutrients serves to drive the excessive growth of algae. However, these algae die or form algae blooms, which are toxic to the plants and animals in the ecosystem. Thus, human activities serve to harm aquatic ecosystems, whenever excess amounts of phosphorus are leached into the water.

1. Name three types of evidence used to support the theory of evolution
Llana [10]

Answer:

1) Fossil evidence Support

2)Genetic evidence supports evolution.

Biological evidence supports evolution;

Explanations;

1)Fossil evidence Support evidence;

This gives the geographic information about many fossils, it gives evidence that two species with a common ancestor can have their development differently and in

different locations. The common ancestor term is crucial especially in

theory of natural selection . In this evidence there is prove that common ancestor is shared through comparison between modern plants and modern algae to fossil algae by scientist.

Examples are bones, exoskeletons, stone imprints of microbes as well as animals.

2)Genetic evidence supports evolution.

This provides the understanding of how traits are passed from one generation to another under the study of DNA, DNA which contains the information needed by all organisms need to grow and to maintain themselves.geneticmaterial are passed to offspring by parent during reproduction. There are code which is made up of different chemical sub unit known as base. posses by DNA that helps to to function properly.

represented by letter A, T, C, and G.

3)Biological evidence supports evolution;

In this evidence, details about how evolution can be observed within the physical structures of adult organisms. is provided. It is evidence that involves of structural evidence such as vestigial structure which means an organisms with organs and similar structures with different functions.

For Example, considering the bodies of whales which is an organisms,there are small leg bones that are vestigial.
