What is standard energy flow in biochemistry?

Energy flow Energy flow is the flow of energy through living things within an ecosystem Energy flow in ecosystem is unidirectional • Energy flows through Food Chains and Food Webs • A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

What is the free energy of a system?

The arrows signify the flow of energy through the community with the sun serving as the primary energy source. A small amount of energy passes from one trophic level to the next; thus, organisms at the higher trophic levels must feed more to obtain sufficient energy for survival.

What are the trophic levels in the food chain?

In a food chain, trophic levels are used to describe the feeding positions of organisms and show how energy flows. Each trophic level has its own unique characteristics. The arrows signify the flow of energy through the community with the sun serving as the primary energy source. A small amount of energy passes from one trophic level to the next; thus, organisms at the higher trophic levels must feed more to obtain sufficient energy for survival.

How do food webs work?

Food webs and food chains are different ways to model how energy flows through an ecosystem. The food chain describes the relationship between different organisms based on what they eat. Thus, for example, grass obtains energy from the sun via photosynthesis, which helps it grow, and grasshoppers feed on the grass for nutrients and energy. Rats eat grasshoppers and owls eat rats. Both the rat and owl obtain nutrients and energy in this manner. A food web is constructed of multiple, interacting food chains.

What is entropy energy?

Entropy can be thought of as the energy that is not available to do work. For example, the oceans contain vast amounts of thermal energy in the form of the motions of individual water molecules. Yet this energy cannot be extracted to power a boat—that requires fuel or wind energy.

What is the law of thermodynamics?

Thermodynamics is the branch of chemistry and physics that deals with the energy flow in physical systems. The First Law of Thermodynamics states that energy in a system is neither created nor destroyed. The Second Law of Thermodynamics deals with the question of whether a reaction will occur: Spontaneous reactions occur with an increase in ...
