What are the correct order of steps on how a reflex occurs? a bone moves. a relay neuron sends a signal to a motor neuron. a muscle receives a signal to contract. a receptor detects a signal. a sensory neuron sends a signal to the spinal cord.

I believe this would be the correct order:

1) A receptor detects a signal.

2) A sensory neuron sends a signal to the spinal cord.

3) A relay neuron sends a signal to a motor neuron.

4) A muscle receives a signal to contract.

5) A bone moves.

A signal will be picked up by a sensory neuron and sent to the spinal cord (Central Nervous System). The signal will then be sent to a motor neuron in the Peripheral Nervous System to find a muscle. That muscle is signaled to contract which then will cause a bone to move.

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.  

the must be sensory neurons.

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
