Food are divided into 7 different groups : drinks, carbs, fruits and vegetables, dairy, meat / fish / eggs, fats and high-sugar foods. Each of these groups provide different nutrients and should be consumed at a different rate. The main sources of our food are Plants and Animals. Plants are the sources of food ingredients like grains, cereals, vegetables and fruits. Animals are the another source which provide us with milk, meat products and eggs.

Leaves are colored by molecules called pigments. The pigment that causes leaves to be green is chlorophyll. Chlorophyll is important for plants to make food using sunlight. ... As chlorophyll goes away, other pigments start to show their colors. The leaves of most plants are green, because the leaves are full of chemicals that are green. The most important of these chemicals is called “chlorophyll” and it allows plants to make food so they can grow using water, air and light from the sun.

The three pigments that color leaves are:

• chlorophyll (green)
• carotenoid (yellow, orange, and brown)
• anthocyanin (red)

The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30–65 km (20–40 miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds occur. The eye is so calm because the now strong surface winds that converge towards the center never reach it. The coriolis force deflects the wind slightly away from the center, causing the wind to rotate around the center of the hurricane (the eye wall), leaving the exact center (the eye) calm.

An animal is a living creature such as a dog, lion, or rabbit, rather than a bird, fish, insect, or human being. ... Any living creature other than a human being can be referred to as an animal. Language is something which fundamentally distinguishes humans from animals. They are multicellular, eat other organisms in order to get energy, and move about during part or all of their lives. Flying is not a special characteristic of birds. The six basic animal groups include amphibians, birds, fish, invertebrates, mammals, and reptiles. Although there are many other groups of animals, and the way scientists classify and categorize species changes frequently, in this article I'll keep it simple by focusing on just six basic groups.

Characteristics of Mammals:

i. Usually terrestrial, only a few are aquatic.

ii. Body is covered with hair and contains sweat and oil glands.

iii. Females have mammary glands which produce milk to feed their babies.

iv. Teeth are present.

v. Diaphragm is present.

vi. They are warm-blooded.

vii. Larynx of mammals is functional.

viii. They have limbs for locomotion.

ix. Lungs are the respiratory organs.

x. Mammals are viviparous, that is, they give birth to their young ones.

Example: Human beings and monkeys.

Animals, plants, and all living things are adapted to life in their natural surroundings. These different environments are called habitats. They range from burning hot, dry deserts, to rain-soaked tropical forests, to frozen tundra.
