A streamlined body is a shape that decreases the friction drag between a fluid, such as air and water, and an object that passes through that fluid. Drag is the force which reduces the speed of the motion. A special shape of the bodies which reduces the fluid friction is called as the streamlined shape. Example: Aquatic animals like fish, crocodile and sharks and the vehicles like cars, flights, ships ect. Streamlined shapes help reduce the amount of air drag when an object is moving.

There are four types of movable joints in the body; which are as follows:
- Ball and socket joint: In this joint the rounded end of one bone fits into the cavity (hollow space) of another bone. It permits movement in all directions. The joints between shoulder and the upper arm is an example of ball and socket joint. Similarly, the joint between thigh and hip is an example of ball and socket joint.
- Pivot Joint: This type of joint allows movements in many planes, viz. up and down, side to side movements. The joint between the skull and the vertebral column is an example of pivot joint.
- Hinge joint: This joint is similar to the hinges in a door. This joint allows movement only in one plane and only up to 1800. The knee joint and elbow joint are examples of hinge joint.
- Gliding joints: The movement in this joint happens due to sliding of bones over one another. Joints between the rings of the backbone are examples of gliding joint. The wrist joint is also an example of gliding joint.

Types of Joints
- Fixed joints: The joints where no movement of bones is possible are called fixed joint. The joints in the skull bone (cranium) are examples of fixed or immovable joints.
- Moveable joint: Movement is possible in these joints. There are two types of movable joints:
- Freely movable joints and
- Partially movable joints.

Vitamin D is a very important nutrient that is responsible for strong bones and teeth. Usually, exposure to the sun triggers the production of vitamin D in the body. Apart from this, vitamin D can also be obtained from red meat, egg yolks and fatty fish like tuna and mackerel. Vitamin D is available in two forms – vitamin D2 and vitamin D3. Low levels of vitamin D3 can have drastic impacts on human health and are abundantly found on the skin of animals. Compared to other vitamins, vitamin D3 has a great impact on bone health, insulin control, low blood pressure, cancer prevention, etc.

Heterotrophs are organisms which cannot prepare their own food and depend upon producers or green plants and other animals for their food. This mode of nutrition is known as the heterotrophic mode of nutrition.
Heterotrophs rely on autotrophs to provide a continuous supply of new organic molecules. Heterotrophs are considered as consumers in the food web and are placed at a secondary or tertiary level.
