What happens to a species when the environment undergoes a radical change (e.g. due to climate, food source) and the organisms do not adapt? Explain your answer in not less than 3 sentences. May cite a hypothetical; situation to explain the answer.

Answers

Answer:

If an environment rapidly changes and an organism cannot adapt it will mostly die out. For example, some birds have long, thin beaks that let them reach insects inside trees. If these insects were to disappear for some reason and seeds became the main food source then the birds with long, thin beaks would not be able to eat. Other birds with different adaptations, like short, strong beaks, would be properly adapted to this new environment. So, this second species would replace the first species.

The path of audition is given below in order:

Sound wave ---> Pinna ---> Auditory Canal ---> Tympanic Membrano Malleus ---> Incus ---> Stapes ---> Oval window ---> Round window ---> Cochlea ---> Organ of Corti ---> Auditory Nerve ---> Superior Olivary Complex Dorsal Cochlear aucleus ---> Inferior colliculus ---> Medial Geniculate body Auditory Cortex --->
