what is the difference between energy flow and chemical cycling?
315160
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are ultimately recycled in the ecosystem while the energy is ultimately lost from the ecosystem to the universe at large. ... Primary consumers then eat the plants for energy.

There are no 'similarities' or 'differences' they are just two different things going on at once simultaneously and cannot happen without each other. You can only say that the difference is that energy cannot be created or destroyed just changes its form and flows. The energy is flowing while the matter is cycling.

Activation energy is the minimum amount of energy it takes to start a chemical reaction. ... An activated complex is an unstable state that is between the reactants and the products in a chemical reaction. A catalyst is a substance that changes the rate of a chemical reaction without being consumed in the reaction.

Part of the chemical energy is converted to the kinetic energy of the car, while part is converted to thermal energy as heat emitted from the engine. Energy can change forms in a similar way in living organisms.

When a chemical reaction occurs, energy is transferred to, or from, the surroundings. An exothermic reaction releases heat to the surroundings and an endothermic reaction absorbs heat from the surroundings.

This differences leads to other aspects of these two types of transport to be different as well. This difference is that active transport needs energy, while facilitated diffusion does not need energy. The energy that active transport uses is ATP (adenosine triphosphate).

activation energy: The minimum energy required for a reaction to occur. catalysis: The increase in the rate of a chemical reaction by lowering its activation energy. transition state: An intermediate state during a chemical reaction that has a higher energy than the reactants or the products.

Equilibrium and Steady State. A state of chemical equilibrium is reached when the concentration of reactants and product are constant over time (Wikipedia). ... In contrast, steady state is when the state variables are constant over time while there is a flow through the system (Wikipedia).

The difference between heat flow and heat flux is that heat flux it the heat flow per area unit, as described in the formula below. Heat is the flow of energy due to difference of temperature. The area is perpendicular to the heat flow direction, regardless of the heat trnsfer mechanism.

Energy can be converted from one form (stored) to another (kinetic) but it cannot be created or destroyed. Thus, chemical is not renewable but is non-renewable. The potential for energy is present in many of the naturally occurring resources around us and that confuses the question.

Two primary classes of thermodynamic cycles are power cycles and heat pump cycles. Power cycles are cycles which convert some heat input into a mechanical work output, while heat pump cycles transfer heat from low to high temperatures by using mechanical work as the input.

The difference between the energy of the reactants and the energy of the products is called the enthalpy change (∆H) of the reaction. For an exothermic reaction, the enthalpy change is always negative. In an endothermic reaction, the products are at a higher energy than the reactants.

Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred.

What is the difference between joule heat and power? When electric current flows in a circuit, energy is transferred from one point to another. The electric energy is not completely transferred but a portion of it is converted to heat energy. This is similar like friction force opposing some mechanical work.

Difference Between Cell and Battery. The cell and battery both store the chemical energy and then transforms the stored chemical energy into an electrical energy. One of the major difference between the cell and the battery is that the cell is the single unit, whereas the battery is the group of cells.

Key Points. Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.

Which statement best describes the difference between light energy and chemical energy? Light energy is a type of kinetic energy, and chemical energy is a type of potential energy.
