Market price support (MPS) is an indicator, developed by the OECD, [1] used in the calculation of Producer and Consumer Subsidy Equivalents (PSE/CSE). The PSE and CSE acronyms were changed in 1999 to Producer and Consumer Support Estimate .
For example, the sun releases 10,000 J of energy, then plants take only 100 J of energy from sunlight (exception- Only 1% of energy is taken up by plants from sun); thereafter, a deer would take 10 J (10% of energy) from the plant. A wolf eating the deer would only take 1 J (10% of energy from deer).
Optimal foraging theory has been used to predict animal behaviour when searching for food, but can also be used for humans (specifically hunter-gatherers). Food provides energy but costs energy to obtain. Foraging strategy must provide the most benefit for the lowest cost – it is a balance between nutritional value and energy required.
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
the economic production price. This price, a total cost-price (i.e. a replacement cost) equals the average cost price and average profit rate of an output at the point of sale to the final consumer, including all net costs incurred by all the different enterprises participating in its production (factory, storage, transport, packaging etc ...
A graphic shows detections of chronic wasting disease in wild and captive deer in Wisconsin. The data spans late 2001 to early 2023.
The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...
The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium. External parameters generally means the volume, but may include other parameters which ...
