As you just learned, in real ecosystems, trophic efficiencies usually vary from about 5% to about 20%. as a result, net producti

on diagrams for ecosystems have a pyramid shape. two key factors explain why trophic efficiencies are relatively low, and thus why net production diagrams are shaped like pyramids.

When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are: 
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.

What strategy can prevent cross-contamination?
mario62 [17]
<span><span>Implement a personal hygiene program. To lessen the possibility of food handlers contaminating food, institute a good personal hygiene program that includes policies addressing critical hand practices like proper handwashing, hand care and glove use. Also address staff cleanliness and work attire, focusing on topics such as bathing, clean clothing, the proper use of hair restraints and prohibited jewelry. Finally, policies should be put in place to make sure food handlers come to work healthy. Include actions such as reporting illnesses and covering wounds.</span><span>Remind employees to wash their hands. This is especially important after using the restroom and after handling raw meat, seafood and poultry. Once employees have washed their hands, ensure they use a single-use paper towel or hand dryer, rather than any part of their uniform, to dry. </span><span>Use separate equipment. Each type of food should be prepped and handled with a separate piece of equipment. For example, use one set of cutting boards, utensils and containers for raw poultry. Use another set for raw meat, and use a third set for produce. Some operations use colored cutting boards and utensil handles to help keep equipment separate. If this system is not possible at your restaurant, prep food at different times.</span><span>Clean and sanitize all work surfaces. All work surfaces, equipment and utensils should be cleaned and sanitized after each task. Simply rinsing equipment is not enough to eliminate pathogens that can contaminate food. </span><span>Purchase prepared food. You can prevent cross-contamination by purchasing food that doesn’t require much prepping. This minimizes handling and can reduce the transfer of pathogens from one surface or food to another.
