If the following events are arranged in the order in which they occur for an animal hiding and holding still in response to seeing a predator, which is the fourth event in the series?.

Answers

Animal hiding-holding still response follows the reflex arc sequence. The fourth event in the series is option B) signaling by efferent PNS neurons.

When the animal receives the stimuli, it responds to them. In the case of hiding-holding still response, the animal might freeze due to motor inhibition that reduces excitatory signals.

The reception and reaction to stimuli follows the reflex arc sequence.

What is reflex arc?

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

We can confirm that Increased ethanol production is not a consequence of bioenergy use.

Why is ethanol production not a consequence of bioenergy?

This has to do with the fact that there would be no need for increased production of ethanol when using bioenergy. This is due to the fact that biomass naturally produces ethanol and that most bioenergy does not rely on ethanol to be created.

Trophic levels are the levels of energy transfer from lower to higher levels.

There are five levels of trophic level.

The lower level contains autotrophs or producers. And the uppermost level contains big animals or tertiary consumers.

The energy level decreases on going to the higher levels because some amount of energy always lapses as entropy.
