3.3 Cycles of Matter Recycling in the Biosphere Unlike the one-way flow of energy‚ matter is recycled within and between ecosystems Elements‚ chemical compounds and other matter are passed from one organism to another and from one part of the biosphere to another through biochemical cycles It connects biological‚ geological and chemical aspects of the biosphere Matter can cycle through biosphere because biological system do not use up matter; they transform Uses same molecules again and again

Chemical Fertilizers vs. Organic Fertilizers INTRODUCTION Agriculture is the most primitive occupation of the people which mainly needs land to grow different crops for food and as raw materials for different industries. Industrial use of agriculture for supplying raw materials came much later. Originally land was used for agriculture to supply food for human beings by the use of organic manures particularly animal dung. At the beginning land was used in its natural form to grow food. Land contains

Eco-Column Lab Write up Alicia Whiteley Block 4 Abstract: In this research and experiment we were testing whether or not we can maintain a healthy eco-system based off creating one from scratch. We initially went into this experiment confident that we were going to be able to keep our fish alive which was proven wrong mid-way through due to high levels of turbidity and the state of the fish. After collecting all of our data‚ we maintained a healthy terrestrial level and a good PH

environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria into nitrates and nitrites‚ which are utilized by the plants as nutrients. The water is then recirculated back to the aquaculture system. As existing hydroponic and aquaculture farming techniques form the basis for all aquaponics

1. In naturally fertile soil‚ microbes ward off pathogens‚ provide a protective layer around plant roots‚ excrete preferred forms of nitrogen‚ and maintain oxygen and moisture levels through denitrification and fixation. (Hermary). 2. As a result of repetitive application of synthetic fertilizer‚ enhanced degradation occurs‚ allowing oxygen‚ nitrogen‚ moisture‚ and pH levels to reach far beyond the normal range‚ ultimately over-stressing and terminating large portions of microbial

soil contains less than twenty percent of the necessary organic nutrients needed to meet our current food production. Carbon‚ hydrogen‚ and oxygen used to synthesize compounds needed for structural integrity are readily available from air and water. Nitrogen‚ phosphorus‚ and potassium‚ the building blocks for healthy plants‚ are usually not present in sufficient amounts in the soil to support plant growth. These are known as macronutrients. In addition‚ micronutrients‚ such as calcium‚ sulfur‚ and magnesium
