What is Nutrition?

The process of taking the food in and then utilizing it for growth, metabolism, and repair is called nutrition.

What are the Different types of nutrition?

There are two major types of nutrition: autotrophic nutrition and heterotrophic nutrition.

● What is Autotrophic nutrition?

The nutrition in which organisms prepare their own food by converting inorganic substances into organic substances is called autotrophic nutrition.

The organisms that can produce their own food are called Autotrophic organisms or

Producers.

For example, Plants.

● What is Heterotrophic nutrition?

The nutrition in which organisms cannot produce their own food and are dependent on autotrophic organisms or other organisms for nutrition is called heterotrophic nutrition.

The organisms that cannot produce their own food are called Heterotrophic organisms or Consumers.

For example, Animals.

What is Photosynthesis?

• The process in which plants absorb carbon dioxide and water, and convert Light Energy

into Chemical Energy is called photosynthesis.

• This process occurs when the absorbed sunlight helps in splitting up the water
• This results in a cascade of reactions through which the plant synthesizes

Carbohydrates.

What are the Most essential components for the process of photosynthesis?

• Carbon dioxide and water

Carbon dioxide and water are the first reactants in photosynthesis. They are mandatory for the synthesis of carbohydrates.

• Sunlight

The plant uses light energy from the sun to make glucose.

● Chlorophyll

Chloroplasts are the location of photosynthesis. Chlorophyll is a green-coloured pigment that is present in chloroplasts. It has reaction centres that are capable of absorbing light.

● Stomata

Stomata are the pores that allow gaseous exchanges between the plants and the surroundings. The carbon dioxide enters the leaves through these pores.

The excess water also moves out through these pores and this process is called

Transpiration.

• Minerals

Plants need minerals like magnesium, potassium, iron, and nitrogen. These are absorbed from the soil.
