- Grass eating animals like cows, buffaloes are called ruminants because they have a separate part of stomach called rumen .They quickly swallow the grass and is stored in rumen where it is partially digested forming cud.
- Rumination is the process by which cud returns to the mouth in small lumps and then the animal chews it.
- Grass contain cellulose which is digested by special bacteria present in a sac like structure located between small intestine and large intestine.

Heterotrophic nutrition can be one of three types – holozoic, saprophytic or parasitic.
Holozoic nutrition can be seen in most vertebrates and some unicellular organisms like the amoeba.
Saprophytic nutrition is where the organisms feed on dead and decaying matter. Examples include bacteria and fungi.
Parasitic nutrition is where an organism lives in or on its host and acquires nutrition at the expense of its host. Examples include lice and tapeworms.

- Periodic Motion or Oscillatory Motion: When an object repeats its motion after every fixed interval of time, the motion of the object is called PERIODIC MOTION OR OSCILLATORY MOTION.
- Oscillation: The motion of pendulum starting from one extreme end to another extreme end and back to the first extreme end is called one oscillation.
- Time Period: Time taken to complete one oscillation by the pendulum is called time period.

Chlorophyll is a green coloured pigment found in plants. It is also called as the green blood of plants due to the fact that it has very similar chemical structure to Haemoglobin in human blood. It is a complex organic molecule, responsible for photosynthesis in plants and in some other organisms. All the organisms get food only because of chlorophyll in plants.

Small intestine
Active nutrient absorption occurs throughout the small intestine, including rumen bypass protein absorption. The intestinal wall contains numerous “finger-like” projections called villi that increase intestinal surface area to aid in nutrient absorption

Soil is the major "switching yard" for the global cycles of carbon, water, and nutrients. Carbon, nitrogen, phosphorus, and many other nutrients are stored, transformed, and cycled through soil. Decomposition by soil organisms is at the center of the transformation and cycling of nutrients through the environment. Diffusion is the process by which nutrients spread from areas of high concentration to areas of low concentration. When roots absorb nutrients from soil solution the concentration of nutrients surrounding the root drops. As a result, nutrients in areas of higher concentration in soil solution migrate toward the root.

Fats take longer time to digest than carbohydrates.
When it comes to fats they cannot be digested so easily since they are quite insoluble in water and are thereby present as large globules.
The bile juice that gets secreted breaks down the fat from bigger droplets into smaller ones.

Plants obtain most of the nutrients other than carbohydrates from the soil by their roots. Thus if the soil is deficient in any nutrient they are enriched by using fertiliser , so that plants can absorb them through roots. Soil has certain bacteria that convert gaseous nitrogen into a usable form and release it into the soil. These soluble forms are absorbed by the plants along with water. Plants can then synthesise components of food other than carbohydrates such as proteins and fats.

In the duodenum, segmentations help to mix chyme with bile and pancreatic juice to complete the chemical digestion of the chyme into its component nutrients. Peristalsis waves begin at the stomach and pass through the duodenum, jejunum, and finally the ileum. The small intestine is good for absorption since it has a large inner surface area. This is formed due to the plicae circulares which project many tiny finger-like structures of tissue called villi. The individual epithelial cells also have finger-like projections, which are called known as microvilli.

Nutrition can be defined as a process by which organisms take in the food and utilize it in order to survive. Based on the mode of nutrition organisms can be divided into two categories:
-
Autotrophic Organisms - They can prepare their food by themselves such as plants
-
Heterotrophic Organisms - They depend upon other organisms for their food such as animals

Chlorophyll is the green pigment found in green plants, algae, and cyanobacteria. It is a complex molecule made up of carbon, hydrogen, oxygen, nitrogen and magnesium. Chlorophyll makes it possible for plants to convert carbon dioxide and water, in the presence of sunlight, into oxygen and glucose during the process of photosynthesis.

Chlorophyll molecules are contained inside chloroplasts, which are the food producers of the cell found in all green parts of a plant. Inside the chloroplasts, we also find thylakoid membranes, which contain photosystems. Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems, which are embedded in the thylakoid membranes of chloroplasts.

Shearing: The fleece (hair) of sheep is shaved off along with a thin layer of skin. In olden days this was done using pair of metal blades. But now-a-days machine is used to cut off the fleece. This is similar to shaving of beards or hair. This process is called shearing.
Shearing is generally done in summer so that sheep could get new hair by winter to get protection against cold.
Sorting: After scouring, fleece is sorted according to texture. This process is called sorting.
