Chloride ions are more concentrated in the extracellular fluid around a neuron than in the intracellular fluid inside a neuron. If a neurotransmitter binds the neuron, causing chloride ion channels to open, chloride ions will

rush into the neuron.

Explanation:

This is because of diffusion, which states that things will move from higher to lower concentration.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the answer is :
