The Flow of Matter and Energy Learning ..

The Connection between Organic Matter and Energy
Simply put, nature stores energy using carbon. Take crops growing in a field. Plants use energy from sunlight, carbon dioxide (CO2) from the air, and moisture from the soil to create carbohydrates (CH2O) through photosynthesis (Figure 1). Carbohydrates are the building blocks of life. In other words, they are the basic ingredients of OM.
Conversion of energy to organic matter, sometimes called Primary Production, also takes place in aquatic environments (Figure 2). Aquatic plants, plankton, and some microorganisms use photosynthesis to create OM and pass it further up the food chain.
Written as a simple chemical formula, photosynthesis is:

Ecosystems | Lesson 3 - Matter Cycles and Energy Flows …

Energy flow is shown with solid arrows and the flow of matter with dashed arrows.

Lesson 3: Matter Cycles and Energy Flows in Ecosystems

By considering ecological systems as "open" rather than "closed," and by allowing for continual inflow and outflow of materials, energy, and organisms, one can partially overcome this difficulty and the community concept can be quite useful. Cycles & Energy Flow | SciMathMN

Global estimation of the required N-Entropy and Energy flow could be estimated for a particular subsystem on Earth or for whole Earth and compared with available N-Entropy and Energy flow for a particular region.

A really complete food web would also include the rates of flow of energy and materials among the various populations comprising a community.

Matter and energy flow recycling 1

In Activity 3.5 students use the Explanations Tool for Ecosystems to explain the reason for the key pattern in this unit: the biomass pyramid. Students use their knowledge of energy flow and matter cycling to explain why the producer pool has more organic matter than the herbivore pool, and why the herbivore pool has more organic matter than the carnivore pool.

Energy & Matter: Flows, Cycles and Conservation

In Lesson 3 students develop complete explanations for what causes the organic matter pyramid, the key pattern in ecosystems they examined in Lesson 2. Using carbon pools as a context, students trace matter through representations that connect carbon-transforming processes at the atomic-molecular, organismal, and ecosystem scales, and they consider the differences between matter cycling and energy flow through ecosystems.

b) In order to maintain Final System certain minimum flow of N-Entropy (Information) and Energy is required.

The Flow of Matter and Energy in the Living World

In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.

Students' understanding of energy flow and matter …

The organizing flow of negative entropy develops more complex structures from organic and non-organic matter and these structures in turn compete with each other, due to limited resources in terms of space, matter, energy and entropy.

Then by focusing on photosynthesis, cellular respiration, and food chains, students discover how matter and energy flow through the living world.

the cycling of matter and flow of energy.

Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy. Plants then store the potential energy in the form of (biological matter that fuels nearly every animal on earth).
