500 because of the 10% rule when moving up in food chains, for example; patch of grass-200J rabbit eats some of it but doesn’t eat all - 150J the rabbit runs around for a bit and loses energy, the fox doesn’t eat all of the rabbit - 50J ( just a rough example may not be completely right but the concept of the rule is there and the energy).
Ribosomes play a role in protein synthesis. So the answer to your question would be "proteins"

The given statement is False.
Norepinephrine, also called stress hormone is released by adrenal medulla.
It acts as hormone as well as neurotransmitter in the brain and body.
In brain, it increases alertness, focus, vigilance, and promotes formation as well as retrieval of memory. In addition, it also increases restlessness and anxiety.
In body, it increases heart rate, blood pressure, blood flow towards skeletal muscles, promotes the release of glucose from energy stores, and reduces the blood flow towards gastrointestinal system.
Concentrations of this toxin are found in the ant as well as in the lizard and the bird, as they are part of the same food chain. The lizard eats ants and the bird eats the lizard. This phenomenon is called biomagnification.
Biomagnification refers to the cumulative increase in concentrations of a persistent substance as one moves up the food chain (trophic chain).
Biomagnification is therefore a process in which the concentration of a substance present in a biotope increases throughout a food chain; by extension, the result of this process.
