Ответ:

Наземно-воздушная среда — среда, состоящая из воздуха, что объясняет её название. Характеризуется обычно следующим:

Воздух не оказывает почти никакого сопротивления, поэтому оболочка организмов обычно не обтекаемая

Большое содержание кислорода в воздухе.

Есть климат и времена года.

Ближе к земле температура воздуха выше, поэтому большинство видов обитают на равнинах.

В атмосфере отсутствует вода, необходимая для жизни, поэтому организмы селятся ближе к рекам и другим водоёмам.

Растения, которые имеют корень, пользуются минеральными веществами, находящимися в почве и, частично, находятся в почвенной среде.

Минимум температуры был зарегистрирован в Антарктиде, который составлял — 89 ° С, а максимум + 59 ° С.

Биологическая среда распространена от 2 км ниже ур. м., до 20 км выше Ур. м..

Умоляю, прошу, помогите кто может, отдам все свои баллы( у меня их много). Прошууу помогите сократить текст для пересказа. Предложений 10-15. Вот по этому тексту. Заранее спасибо.
1) It's Monday morning and while you are getting dressed, you're looking at yourself in the mirror. 'I'm too skinny. I'd like to put on a little weight and be a bit taller and more muscular,' you think. 'I also wouldn't mind thicker hair, longer legs, better teeth and a smaller nose. Speaking of my nose, is that a pimple on it? Oh, here we go again! I can't go out. I can't stand people staring at me.'

2) Do these remarks sound familiar? Almost everyone would like to change something about their bodies. Teenagers feel that way quite often because their bodies change while they are growing up. As your body changes, so does the way you feel about your physical appearance. Your body image often affects the opinion you have of yourself.

3) As your body matures, you may think that it draws attention to you, and you may feel uncomfortable. You may also compare yourself to your friends to see if you are 'normal'. But growing up doesn't happen at the same speed for everyone. Girls usually start changing sooner than boys. Sometimes, they suddenly put on weight as their bodies need fat to grow. On the other hand, boys notice their shoulders getting wider and their voices getting deeper. These changes usually take place over two to five years.

4) Media images from TV, movies and advertising may also affect your self-esteem. Women and girls on TV and in magazines are usually thin while men look strong and very muscular. This can make you believe that something is wrong with you if you don't look this way. Media images may also put pressure on you to go on extreme diets or become obsessed with weight training. Remember that it's more important to exercise regularly and eat healthily than to try to change your body to fit an unrealistic image. Adverts sell fantasy and vanity, not reality.

5) Although you may often think that your classmates notice every single pimple on your face or every single pound you gain, this is not the case. What they notice is how you feel about yourself. You need to focus on the things you like about yourself and walk with confidence! If you like yourself and the way you look, other people will too!
