Answer: I cant say for sure how many species have to be extinct. But yes a species can become extinct.
Explanation:
The correct answer is known as a "motor neuron".
A motor neuron or also known as a motoneuron is described as <span> a neuron whose </span>cell body<span> is </span>placed inside the<span> motor cortex, brainstem or the spinal </span>cord<span>, and whose axon </span>initiatives<span> to the spinal cord </span><span>or </span>the exterior<span> of the spinal </span>cord<span> to </span>immediately<span> or </span>not directly manage<span> effector organs, </span>specifically muscle mass<span> and glands. </span>
Therefore, primary consumers get about 10% of the energy produced by autotrophs, while secondary consumers get 1% and tertiary consumers get 0.1%. This means the top consumer of a food chain receives the least energy, as a lot of the food chain's energy has been lost between trophic levels.
