Autotrophic Nutrition:
The autotrophs acts as the producers and prepare their own food by using carbon dioxide from air, water from the roots, sunlight and chlorophyll for e.g., chromatium, rhodobacter capsulatus. Some autotrophs also prepare their food by harnessing energy from the oxidization of inorganic chemicals for e.g., methane bacteria. Two types of autotrophic nutrition are phototrophic nutrition and chemoautotrophic nutrition.
Heterotrophic Nutrition:
Some organisms which cannot prepare their own food and depend on green plants and other organisms to convert high energy into their food. Examples: protozoans, liver fluke, decomposer protists, symbiodinium on corals. These could be classified as parasitic, holozoic, saprophytic and mixotrophic.

No, Humans cannot survive only on raw, leafy vegetables, or grass. It is because the grass is rich in cellulose, which is a type of carbohydrate that humans are not able to digest due to the absence of cellulose-digesting enzymes.

A Cyclone is a large scale air mass that rotates around strong centers of low pressure.
- Water vapors are formed when water is heated.
- This heat is released to atmosphere when water vapors convert to water during rains.
- The heat released, warms the air around and makes it to move up. This also results in decreased air pressure.
- Hence, cooler air from surrounding rushes to take the warm air’s place.
- This repeats till a low pressure system with surrounding high speed winds is created. This is called a Cyclone.
- Cyclone depends on wind speed, direction, temperature and humidity.
Cyclones are also called Hurricane in USA and Typhoon in Japan and Philippines

Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.
In nature, organisms exhibit various types of heterotrophic nutrition. They are as follows:
- Holozoic Nutrition
- Saprophytic Nutrition
- Parasitic Nutrition

Rhizobia is "the group of soil bacteria that infect the roots of legumes to form root nodules". Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen. R hizobium is a genus of gram-negative, motile bacteria whose members are most notable for their ability to establish a symbiotic relationship with leguminous plants, such as peas, soybeans, and alfalfa.

Pitcher plant derives nutrition just the way any other plant does . It takes water and minerals from the soil and food by photosynthesis. But the soil in which it grows doesn't has nitrogen so it uses the pitcher for killing small insects and then digesting them to derive nitrogen from the animal.

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7. A neutralisation reaction is a irreversible reaction as products (salt and water) can not be converted back to the reactants (acid and base). It is chemical change converting an acid and a base to salt and water.

Capillaries are the smallest of the body's blood vessels. They are only one cell thick, and they are the sites of the transfer of oxygen and other nutrients from the bloodstream to other tissues in the body; they also collect carbon dioxide waste materials. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.

Green plants synthesise their own food by the process of photosynthesis. The leaves have a green pigment called chlorophyll which helps them to capture the energy of the sunlight.In the presence of sunlight, carbon dioxide and water combine to form glucose and oxygen is released. Photosynthesis is the process of synthesis of food in the plants with the help of chlorophyll and carbon dioxide in the presence of sunlight. Water and minerals present in the soil are absorbed by the roots and transported to the leaves by the vessels. Carbon dioxide from air is taken through stomata present in leaves.

- In parasitic mode of nutrition, plants depend on other plants or animals for their nourishment.
- Such dependent plants are called as parasites and the ones on which parasites depend are called as hosts.
- A parasite plant climbs on the host plant from which they get all the food.
- The host does not get any benefit from the parasite.
- Some examples of parasites are Cuscuta (akash-bel), Cassytha (amar-bel), hookworms, tapeworms, leeches, etc.

Crop rotation is the systematic planting of different crops in a planned sequence over several years in the same growing space. It has following advantages:
1. It controls pests and weeds to a great extent.
2. Two or three crops can be grown in a yewar with good harvests.
3. Soil utilization is complete.
4. It reduces the great dependence on fertilizers.
