Nutrient cycling of the earth

The soil microbes are important in recycling. They release the nutrients by decomposing organic matter. They are important to transform the soil with the help of plant roots.

The energy flow is the transfer of energy from one trophic level to another in the food chain. It is a form of heat and energy is lost from one level to another. The sun is the most energy-rich source.

The rainforest's soil

The tropical rainforest recycles its resources quickly. The warm, moist climate makes it ideal for decomposers to break down organic material quickly. The litter layer is the dead organic material such as fallen leaves, dead wood or dead animals on the surface of the soil.

The soil has dissolved nutrients. The rainforest has a cycle of nutrients. The diagram shows the different stores of the same thing.

Flow-through ecosystems: Slow water movement in low and high temperatures

Flow-through ecosystems are usually open, but the fluxes are much greater from sites of production to the bottom. Water movements are very slow with reductions of physical movements. In lentic environments, there is more of a closed off environment for the cycle of nitrogen in the water.

The Evolution of Soil

Almost all of the landscape is covered by a mixture of rock, organic matter, water, gases, and living organisms. Even for trees as tall as 100 m, soil provides mechanical support. The soil is a component of the entire ecosystems.

silt that was transported by wind from other places is what loess are derived from. The ability to bind many nutrients is one of the important chemical properties of the soil rich in clay. The type of soil that develops is influenced by the characteristics of the parent material.

Climate factors such as precipitation and temperature affect soil development. The soil is very important. Plants get their water and much of the nutrition they need from the soil through their roots.

The soil provides habitat for a great diversity of animals and organisms that play a crucial role in litter decomposition and the cycle of food and water. Denitrification is performed by a wide variety of species and converts nitrate to either N2O or N2 in the atmosphere. When there is a large amount of nitrate in the soil, the rate of denitrification is greatest.

Denitrification can be considered a counter-balancing process. The total amount of nitrogen in the biosphere is not changing much because of the global rates of nitrogen fixation and denitrification. Fats and lipids, nucleic acids, and energy-carrying molecule such as the ATP are all important components of many biochemicals.

The climate of the tropical rainforest and deciduous woodlands

The soil has a large store of soil nutrients due to the input of the weathered rock below the surface and the transfer of the litter layer through decomposition. The growing season lasts for only a part of the year, which causes the low absorption of nutrients. The soil is stripped of its valuable resources.

The tropical rainforest has a slower cycle of the nutrients as temperatures are not as high and there is less rain. The growing season foruous woodlands is shorter as there is less vegetation and less growth of food. The different vegetation layers in the deciduous woodland provide habitats for plants and animals.

The flora and fauna have adapted to the different conditions. Oak trees can support a lot of insects. The woodlands are seasonal.

They are very productive in the summer. There is little growth during the winter and many species are not active. The changing weather conditions present challenges to living organisms, particularly those that only have a few sources of food.

The Biosphere as a bioenergy factory

The movement of nutrients through the biosphere is different from the transfer of energy because elements are recycled. The same atoms of carbon or nitrogen may move between organisms, the atmosphere, the soil, and the oceans over the course of millions of years. Carbon dioxide released by animal may stay in the atmosphere for 5 or 10 years before being taken up by another organisms, or it may be used during photosynthesis and be returned to a nearby plant.

The Phosphorus Cycle

The cycle is called the phosphorus cycle. The water systems of lakes and rivers are mostly made of rocks. They will eventually get into animal and plant life.
