. Trace the path of sound from the outer ear to interpretation by the brain, detailing what happens at each step in the pathway.
scZoUnD [109]
Sound waves enter the external ear and are funneled toward the tympanic membrane by the shape of the outer ear.Variation in air pressure due to sound waves causes the tympanic membrane to vibrate. The wave frequency will determine the vibration rate.Tympanic vibrations cause the malleus to move. Because the three ossicles are connected, this vibration is transduced to the stapes via the incus.Movement of the stapes vibrates the oval window. Significant amplification of sound waves occurs due to the small size of the window.Pressure changes transduced through the oval window vibrate the perilymph in the scala vestibuli which are transmitted across the vestibular membrane to the endolymph of the cochlear duct, and also up the scala vestibuli and down the scala tympani much the way <span>waves move through the ocean.</span>

What would happen to the nutrients in an ecosystem if decomposers, such as bacteria, didn’t exist there?
OLga [1]
<h2><u>Answer:</u></h2>

Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem.

The absence of decomposers in Earth would cause irreversible damage to the planet's wildlife. Carcasses and dead leaves will cover the surface the planet without getting broken down.

If there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.

If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up and life will end for ever and our beautifull will be destroy.
