Ecosystems are divided by trophic levels, which categorizes every organism by class of what kind of consumer they are. 90% of the energy that is available for an organism is lost as it is transferred through each trophic level. Producers, such as the plants of an ecosystem, have available 100% of the energy they can harvest and use 90% of it, thus leaving only 10% of energy left for primary consumers. Primary consumers then leave only 1% of that original energy for secondary consumers. Then secondary consumers leave only .01% of the initial energy for tertiary consumers. It is called the rule of 10% in biology and may be easier to comprehend as a list.
Producers energy total: 100%
Primary consumers energy total: 10%
Secondary consumers energy total: 1%
Tertiary consumers energy total: .01%
And so on...

Which of the following situations or phrases most accurately describes the citric acid cycle?
Bond [772]

The correct answer is: B) "All roads lead to Rome"

Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.

Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
