Answer: 1.Monosaccharides - These are simple carbohydrates, also called simple sugars, which are made of one sugar. They are broken down quickly by the body and are the building blocks for complex carbohydrates.
2.Disaccharides - These are also simple carbohydrates that consist of two chemically-linked monosaccarides. They come in the form of lactose, maltose and sucrose.
3.Oligosaccharides - These are complex carbohydrates that consist of three to ten sugars. They are rich in vitamins and minerals; and, because they are fiber-rich, they are slower to digest than a simple carbohydrate.
5.Polysaccharides - These are also complex carbohydratges and are rich in vitamins, minerals and fiber; but, they have larger numbers of sugars than an oligosaccharide.

Explanation:
Biogeochemical cycles are pathways by which nutrients flow between the abiotic and abiotic compartments of the Earth. The abiotic portion of the Earth includes the lithosphere (the geological component of the Earth) and the hydrosphere (the Earth’s water).
Ecosystems rely on biogeochemical cycles. Many of the nutrients that living things depend on, such as carbon, nitrogen, and phosphorous are in constant circulation.
Essential elements are often stored in reservoirs, where they can be taken out of circulation for years. For example, coal is a reservoir for carbon.
Humans can affect biogeochemical cycles. Humans extract carbon and nitrogen from the geosphere and use them for energy and fertilizer. This has increased the amount of these elements in circulation, which has detrimental effects on ecosystems.
The trout swam through water that was poluted by fertilizer. the fertilizer got to the water by being washed out by rain/ water given to the crops.
1. Flood plain - occasional or periodic flooding is needed to refresh certain nutrients and promote the life cycles of certain species of plants, animals, and soil organisms.
The ecosystem can be disrupted by "flood control" measures, such as dam building, or by flood-altering measures such as deforestation or pavement.
2. Prairie - the rich diversity of life it supports depends on the burrowing, foraging, and grazing animals who live there, as well as the interaction between plant species of different height, depth, and need for water.
The ecosystem can be disrupted by killing off large grazing animals or by fences that prevent their movement. "Sod-busting" for farming or construction also destroys this ecosystem.
3. Forest floor - this ecosystem provides for nutrient support, pest control, and communication between the plants and animals who live there. The largest known organism on Earth (a fungus) lives under forest soil.
The forest ecosystem is badly disrupted by logging, fire control, and other "management" techniques, as well as by paving, construction, and overuse by people. Reforestation projects may put more trees in the ground, but they don't restore the ecosystem. ("The Hidden Life of Trees" is a good book on this subject.)
