Animals intake oxygen and release carbon dioxide. It is also known as breathing. This is mainly two phases.
- Inspiration: It is the process by means of which oxygen is taken to the lungs.
- Expiration: During expiration, carbon dioxide is expelled out from the respiratory organs into the environment.
Example: Through Plasma Membrane: In unicellular animals, such as amoeba, exchange of gases takes place through cell surface. They absorb oxygen from the surrounding air or water and give out carbon dioxide through plasma membrane by diffusion.

Scientist discovered that birds at the back of the V have slower heart rates and flapped less often. This definitely shows that birds benefit more from this flight formation.
According to researchers, the birds mostly fly around a meter behind and a meter off to the side up front. Now when the bird in front flaps its wings a vortex of air directly behind is pushed downwards which is called downwash.

Imagine you are sitting in a moving train,you will observe that you are in motion with the trees,the platforms because your position is continuously changing with respect to them.However, if you compare yourself and the person sitting beside you or in front of you, you will see that their position is not changing.Thus,whether a given object is at rest or in motion depends on the observer and the surroundings.

- Source of Energy: The main function of fats is to provide the body with a rich source of energy. Fats are also used as an energy reserve in the body. When needed, fats can be converted to energy.
- Warmth: The layers of fats beneath the skin act as insulators to keep the body warm.
- Protection: Fats protect vital internal organs such as the kidneys, heart and liver, by surrounding and cushioning them.
- Solvent for vitamins: Fats act as a solvent for certain vitamins in the body. These fat-soluble vitamins dissolve and are stored in fats.

The simplest and the easiest way of making a magnet is by the ‘stroking method’. If we stroke an iron bar with one end of the bar magnet repeatedly in the same direction, the iron bar becomes a magnet.

Similarities between living and non-living
*Living organisms are made up of cells and non-living things are made up of particles.
*Living organisms involve metabolic reactions and non-living things can undergo physical and chemical reactions.
*Living organisms require energy to perform work and this is obtained from food. Non-living things also require energy for any action like movement. Thse also require energy which they obtain from fuel.
Differences between living and non-living
1. Living things can move, but non-living things cannot.
2. Energy is required by living things, while non-livings do not require energy.
3. Living things are capable of growth, reproduction and death.
4. Non-living things are non-motile, but living things can move around.
5. Living things respire; non-living things do not respire.
6. Living things adapt to the surroundings and respond to stimulus.

Underground stems have structures which you would expect to see in stems growing above ground, e.g. buds. These stems might also turn green when exposed to light as they generate chlorophyll. A good example of an underground stem is the part of the potato plant you eat. The 'eyes' are buds which will sprout. Leave a potao out in the light and it will go green. Several plants use underground stems as storage organs, many (especially grasses) use them to spread, for example couch grass; new plantlets emerge from the buds.
Stems are not specialised for water absorption as roots are and root structures reflect this. There are no buds on roots and they do not go green when exposed to light. Many plants do use roots as storage organs, e.g. carrot, dandelion, etc.

Rectilinear Motion – This is a motion where objects move along a straight line. Examples march past of soldiers, sprinters in race, falling stones etc.
Circular Motion - This is a motion where objects move along a circular path. Examples hands of a clock, blades of a fan, rotation of earth around the sun etc.A type of circular motion where an object spins on its own axis, it is called rotational motion. Example rolling ball, spinning top etc.
Periodic Motion – This is a type of motion where the object repeats its motion after a fixed interval of time. Examples pendulum of a clock, motion of child on a swing etc.
