Loss of energy in the food chain limits the amount of energy available to higher trophic levels, such as apex predators, resulting in a decrease in biomass at each successive trophic level. This loss of energy ultimately constrains the overall biomass and productivity of an ecosystem.
There is a limit to the number of links in a food chain due to energy loss at each trophic level. As energy is transferred from one organism to another, some energy is lost as heat during metabolism, making it inefficient to sustain a long chain. This limits the number of trophic levels that can be supported in a food chain.
You can only collect the amount of your actual loss but no more than the limits on the policy. If a person does not have enough limits on his policy and he hit you then you can sue him for more but you will not be able to collect the policy limits amount then still sue for the remainder of the loss.
Every step of energy transformation have loss. Progress through the energy chain, the amount of energy transferred would unavoidably degraded. So as the chain progress it get narrower to a pyramid shape.
The energy loss formula used to calculate the amount of energy dissipated in a system is typically given by the equation: Energy loss Initial energy - Final energy.

The energy that is not passed on to the next trophic level is usually lost as heat through metabolism or used for growth and maintenance by the organism. This loss of energy limits the number of trophic levels in a food chain and is a key principle in ecological efficiency.
Typically, about 10% of the energy is transferred from one trophic level to the next in a food chain or web. This is due to energy loss through metabolism and heat. This limits the number of trophic levels that can be supported in an ecosystem.
True
There cannot be too many links in a food chain. Food chains always begin with a plant and end with an animal. If there are more than 4 or 5 links in the chain , there will not be enough food for the animals at the end of the chain.
The amount of energy passed on to a hawk in a food chain depends on several factors, including the efficiency of energy transfer at each trophic level. Generally, only about 10% of the energy from one trophic level is transferred to the next due to energy loss through metabolic processes, heat, and waste. Therefore, if the hawk is at the top of the food chain, it would receive approximately 10% of the energy from the prey it consumes, which in turn received about 10% of the energy from the plants it fed on. This results in a significant reduction in energy availability as one moves up the food chain.
The Zone diet limits or eliminates the amount of carbohydrates you consume. By limiting carbohydrates, your body is forced to use stored energy, which causes weight loss. A full description can be found here: http://www.zonedietinfo.com/
