Question

Является ли приспособленность видов к условиям существования абсолютной? Подтвердите свой ответ конкретными примерами.

Answer 1

 У животных приспособительной может являться форма тела окраска и поведе­ние. Пример: копыта лошади явля­ются наиболее удобными для быстрого бе­га по открытым пространствам, у водных мле­копитающих рыбообраз­ное тело для наиболее лучшего пере­мещения в воде (кит), у птиц с разной скоростью и характером полета формируется та или иная форма крыла. Некоторые организмы спо­собны принимать окраску, соответствую­щую фону, на котором они живут(хамелеон)                                                                                                                                Ну больше не могу (((( Прости))))

Answer 2

Is Adaptation of Species to Environmental Conditions Absolute?

The adaptation of species to environmental conditions is not absolute. While many species have evolved specific traits to thrive in certain environments, these adaptations are not fixed or unchangeable. Environmental changes, such as climate shifts, habitat destruction, or the introduction of new predators, can lead to the need for further adaptations or even the extinction of certain species.

Examples of Non-Absolute Adaptation:

1. Polar Bears: Polar bears are well-adapted to their Arctic environment, with thick fur and a layer of blubber for insulation. However, as climate change leads to the melting of Arctic sea ice, polar bears are facing challenges in finding food and are increasingly coming into conflict with humans.

2. Darwin's Finches: Darwin's finches in the Galápagos Islands are famous for their beak variations, which have evolved to suit different diets. However, studies have shown that these finches continue to adapt in response to changes in food availability and competition from other species.

3. Peppered Moths: The peppered moth population in England is a classic example of adaptation to environmental changes. During the Industrial Revolution, the dark form of the peppered moth became more prevalent due to camouflage against pollution-darkened trees. However, as pollution levels decreased, the light form of the moth became more common again.

In conclusion, the adaptation of species to environmental conditions is not absolute and is subject to change in response to environmental shifts and other factors.
