Terrestrial (land) animals, inhale air through their noses, mouths, and even their skin, to bring oxygen to their lungs. Water has oxygen too. Fish get the oxygen their bodies need by pumping water over their gills. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land).

Cellulose is the carbohydrate that can be digested by ruminants but not by humans because ruminants have a large sac-like structure called rumen which is located between the small intestine and large intestine. Certain bacteria are present in rumen which helps in digesting cellulose.

When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it ‘bends’ more towards the normal line.
The amount of bending depends on two things:
- Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more.
- Angle of the incident ray – if the light is entering the substance at a greater angle, the amount of refraction will also be more noticeable. On the other hand, if the light is entering the new substance from straight on (at 90° to the surface), the light will still slow down, but it won’t change direction at all.

Insectivorous plants prepare food by themselves, but they lack some of the vital nutrients such as nitrogen since they grow in soil where nitrogen is deficient. They eat some insects and thus make up for these nutrients. Hence they are said to be partial heterotrophs.
Insects are eaten by insectivorous plants to compensate for the deficient nutrients. An insect body has to be broken down before its nutrients can be absorbed into the plant. Carnivorous plants enzymes which help to break down the insect body and release nutrients.

Plant use energy from light to convert water and carbon dioxide into sugar and oxygen in a process called photosynthesis. Thus carbon dioxide is used in preparing food for the plants via a process called photosynthesis.
So the correct option 'Carbon dioxide'.

Global Wind Patterns wind belts of the general circulation. The global wind pattern is also known as the "general circulation" and the surface winds of each hemisphere are divided into three wind belts: Polar Easterlies: From 60-90 degrees latitude. Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies). The global wind belts are the three wind belts or wind patterns that cover the planet: the tropical easterlies (or the trade winds) are found near the equator, the polar easterlies are found at the north and south poles, and the prevailing westerlies are found between the two.

For photosynthesis green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. Each stomatal pore is surrounded by a pair of guard cells. The opening and closing of the pores of stomata is controlled by the guard cells only. After carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars.

Absorption is the process by which the products of digestion are absorbed by the blood to be supplied to the rest of the body. During absorption, the digested products are transported into the blood or lymph through the mucous membrane. The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

A fibre is a thin thread of a natural or artificial substance, especially one that is used to make cloth or rope. If you look at the paper under a microscope you will see the fibres. ... Fibre consists of the parts of plants or seeds that your body cannot digest. Fibres that are obtained from plants or animals are called natural fibres. Examples are cotton, jute, wool, and silk. Fibres that are made by man from chemical substances are called synthetic fibres. Examples are nylon, rayon, polyester, and acrylic.

Rayon is known as artificial silk as this fibre resembles silk in properties. It is obtained by chemical treatment of wood pulp of cotton. Rayon resembles silk, so it is also known as artificial silk. Artificial silk or rayon is produced in mills, is produced in bulk at one time and requires less labour and skill whereas original silk is produced by the silk worms and it requires a lot of skill, labour and time to treat the worms and extract silk from them. Hence artificial silk is cheaper than natural silk.
