Carbohydrates, proteins, fats, vitamins and minerals are essential components of food, these components are called nutrients.
Mode of nutrition
- Autotrophs or Autotrophic: - Plants that have chlorophyll trap the energy from the sun and prepare their own food. Such nutrition wherein the food is prepared by the organisms itself is called autotrophic nutrition. The organisms capable of preparing their own food are called autotrophs. All green plants are Autotrophs (Auto means self and trophos means nourishment). They prepare their own food by a process called photosynthesis.
- Heterotrophs or heterophobic: - Heterotrophic organisms are those who obtain food from other organisms. Since these organisms depend on other organisms for their food, they are called consumers. All animals and non-green plants like fungi come under this category.Organisms that follow the heterotrophic mode of nutrition are called heterotrophs.

Farmers grow fruits and vegetables crops inside large green house because it protects it from high blowing wind, and rodents also green house protects the plant from the climatic conditions of outside and it can have its own suitable temperature for the growth of plants.
Farmers get advantages of the following things:
(i) They have control over their climatic conditions (Temperature, humidity etc.)
(ii) Free from pests, rodents and also from birds and animals so they have increased producibility.

To lead the farmer to the hidden gold, the dog came running to the farmer and kept its paws against his legs. It continuously kept directing towards a place behind him. The old man at first thought that the dog is just playing but when it kept running and whining, the old man followed to the place.

- If [H+] > 10-7, pH is less than 7 and the solution is acidic.
- If [H+] = 10-7, pH is 7 and the solution is neutral.
- If [H+] < 10-7, pH is more than 7 and the solution is basic.

When we believe that people belonging to particular groups based on religion, wealth, language etc. are bound to have certain fixed characteristics or can only do a certain type of work, we create a stereotype. For example, we see how boys and girls are made to take certain subjects not because of their aptitude but only because they are either boys or girls. Stereotypes prevent us from looking at people as unique individuals.

Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers). Three latitudes are used in this way: the geodetic, geocentric and parametric latitudes are used in geodetic coordinates, spherical polar coordinates and ellipsoidal coordinates respectively. The seven important lines of latitude are the equator at 0 degrees, Tropic of Capricorn at 23.5 degrees south, Tropic of Cancer at 23.5 degrees north, Antarctic Circle at 66.5 degrees south, Arctic Circle at 66.5 degrees north, the South Pole at 90 degrees south and the North Pole at 90 degrees north.

demonstrate that chlorophyll is essential for photosynthesis.
Requirements : A potted plant with variegated leaves - for example, Croton or money plant (variegated leaves are partly green and partly white), rice paper, pencil, white paper sheath, beaker, test tube, 70% alcohol, KL solution, water bath.
Method : Keep the potted plant with variegated leaves in dark for three days so that the leaves become free from starch. Then place the plant in bright sun light for about 6 hours. Take a variegated leaf of the potted plant kept in bright sunlight. Trace the outline of leaves and its variegated parts on the tracing paper (the variegated leaves show pale yellow spots in green leaves. These areas indicate the absence of chlorophyll). Dip the leaf in boiling water for a few minute. Now boil the leaf in 70% alcohol till it decolorizes. Now dip the leaf in boiled water to make the leaf soft. Take out the leaf and stain with iodine (KL) solution. Observe the change in colour.
Observation : The blue colour appears only in those parts of leaf which were green in colour. The blue colour will not appear in variegated parts. This shows that starch formation takes place only in green (chlorophyll containing) parts of the leaf. Thus, the chlorophyll is essential for photosynthesis.

Nutrition is of two types namely, autotrophic and heterotrophic mode of nutrition. Plants exhibit autotrophic mode of nutrition. They prepare their own food by the process of photosynthesis.
There are two modes of nutrition:
- Autotrophic – Plants exhibit autotrophic nutrition and are called as a primary producer. Plants synthesis their food by using light, carbon dioxide and water.
- Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
