344 12.4.1 Nutrient Excess in Fresh and Marine Waters 12.4.2 Nutrient Deﬁciencies 24. Plants and animals are part of all of the nutrient cycles through the foods they eat and what eats them (food chains and food webs). Name the four classes of organic compounds (containing carbon) and explain how the carbon cycle and nitrogen cycle contribute to the usable supplies of these macromolecules. 25. Also, biogeochemical (nutrient) cycles connect past, present and future forms of life. Thus some of the carbon atoms in the skin of your nose may once have been a part of a petal, a dinosaur’s skin, or even a diamond! 5.6 RECAPITULATION J Nutrient cycles are the link between abiotic and biotic components of ecosystems.

Hence, it is important to understand the factors controlling their transport and sedimentation.

Nitrogen Cycle Worksheet Introduction: Nitrogen cannot be used directly. Plants and animals need nitrogen to make proteins in animals and chlorophyll in plants. Animals are able to obtain nitrogen through eating plants and animals. Nitrogen goes back into the soil through animal wastes and decomposing animals and plants. As one of the most respected nutrition life cycle texts in the higher education market, NUTRITION THROUGH THE LIFE CYCLE, Fifth Edition uses current research to explain the nutritional foundations necessary for the growth, development, and normal functioning of individuals in each stage of the life span.

NUTRIENT CYCLE IN NATURAL ECOSYSTEM Nutrient cycling plays an extremely significant role in maintaining ecosystems general functioning. Nutrients are central to the function and growth of organisms, and in an ecosystem, decomposer organisms are essential in breaking down biomass matter and cycling nutrients. Nutrients in soil solution – At the heart of the nutrient cycle (Figure 2) are the nutrients in soil solution which are in the form of free ions (ex: cations such as NH 4 + and anions such as NO 3-) or in other soluble forms, such as chelates. Chelates – Some nutrients bond with soluble organic compounds in soil to form ring complexes Nutrients like carbon, nitrogen, sulphur, oxygen, hydrogen, phosphorus and other inorganic elements of the soil, atmosphere, and etc.
