1. Lay down a sheet of wax paper.
2. Place a container at the center. Use a container (soda can, mason jar, plastic bottle, etc.) to form the center of your volcano. This is where you will mix your lava.
3. Use clay to make the rest of the volcano. Mold the clay from the base to the top of the can. Try to make it look lumpy instead of smooth, since real volcanoes don’t look like perfect cones most of the time.
4. Leave for one hour or until dry.
5. Mix your vinegar. Color some vinegar with red food coloring and mix in a tablespoon of dish soap.
6. Pour the mixture into the volcano.
7.Package your baking soda. Take baking soda and pour it on a square of toilet paper or paper towel. Fold up the toilet paper/paper towel. Keep it closed with rubber bands.
8. Drop the baking soda roll in the vinegar.
9. Step away. Once the paper dissolves, your volcano will explode.

Heterotrophic nutrition is that mode of nutrition in which an organism cannot make its own food from simple inorganic materials like carbon dioxide and water, and depends on other organisms for its food. Holozoic nutrition: It is that nutrition in which an organism takes the complex organic food materials into its body by the process of ingestion; the ingested food is digested and then absorbed into the body cells of the organism.
Example: Human beings

Covering the leaves with wax will close the stomatal opening present on leaf epidermis. Stomata helps in gaseous exchange and water evaporation or loss from leaf surface. Closing of stomata affects the rate of transpiration and respiration.

The human digestive system consists of the alimentary canal and its associated glands. Food is taken into the body through the mouth.
Digestion in human beings starts in the mouth. The mouth contains teeth, tongue and salivary glands. The teeth cut the food into small pieces, chew and grind it. The tongue mixes the food with saliva. The salivary glands secrete a watery liquid called saliva.
The slightly digested food goes into the food pipe or oesophagus by peristalsis. No digestion of food takes place in the oesophagus.
The slightly digested food reaches the stomach through oesophagus for further digestion where it is broken down into smaller pieces. The inner lining of the stomach secretes gastric juice which includes mucus, hydrochloric acid and digestive juices. Mucus protects the lining of the stomach from hydrochloric acid. Hydrochloric acid makes the medium in the stomach acidic to facilitate the digestion of proteins. The digestive juices break down the protein into simpler substances. Then the partially digested food goes into the small intestine.
The small intestine is a very long and narrow tube where complete digestion of food takes place. It receives secretions of liver, pancreas and its own walls. Liver secretes liquid called bile which helps in the digestion of fats and converts them into small droplets. Pancreas secretes pancreatic juice which breaks down fats into fatty acids and glycerol. Pancreatic juice also breaks down carbohydrates and proteins into simpler forms. The intestinal juice secreted by the walls of small intestine breaks down the carbohydrates into glucose, proteins into amino acids. Thus, the food gets completely digested in small intestine.

Starfish feeds on animals covered by hard shells of calcium carbonate. After opening the shell, the starfish pops out its stomach through its mouth to eat the soft animal inside the shell. The stomach then goes back into the body and the food is slowly digested.
