Most starfish eat mollusks, principally bivalves which they force open by seizing both halves of the shell with their tube feet and pulling the halves apart very slowly until the bivalve is exhausted.
A traditional curriculum uses older methods like lecturing in a classroom. Progressive programs experiment with newer methods like online learning.

Heterotrophs are organisms that uses organic compound as its source of food whereas detritivores are organism that uses organic waste as its source of food.
The body uses carbohydrates for energy.fruit , vegetables and water
The human body breaks down food for absorption and assimilation through the process of digestion. Both mechanical and chemical digestion is used to spread the food pieces through the human body.
The scientific method and peer review are two methods that a scientist uses to obtain empirical evidence. Experimental design and reproduction of results are two other methods.
An amoeba
Stentor uses hair like structures known as ciliato obtain food.
A starfish uses its arms to pry open clam or oyster shells
The underside of a starfish has many sucker like legs that the starfish uses to walk over the ocean floor - it is not smooth.

Subsistence patterns refer to the ways in which societies obtain food and resources to meet their basic needs. This includes hunting and gathering, pastoralism, horticulture, agriculture, and industrialism. The choice of subsistence pattern can have a significant impact on social organization and cultural practices within a society.
The starfish can find food using the tips of its legs. When it finds food (a shellfish like a clam, oyster, scallop) it wraps around the back side of it and uses its suction cups to pry the thing open. Next, its stomach comes OUT of its body through a hole in the center, enters the now helpless shellfish, and eats the inside.
The main difference between convection and microwave cooking methods is the way heat is transferred to the food. Convection cooking uses hot air to cook food evenly, while microwave cooking uses electromagnetic waves to heat food quickly from the inside out.
It uses different types of platnts for a shelter.
Physical methods of food preservation involve techniques that alter the physical state of food to inhibit spoilage and extend shelf life. Common methods include refrigeration and freezing, which slow microbial growth; drying, which removes moisture to prevent spoilage; and canning, which uses heat to destroy pathogens and seal food in airtight containers. Other methods include pasteurization, which uses heat to kill harmful bacteria, and vacuum sealing, which removes air to reduce oxidation and microbial growth.
They have two stomachs because the cardiac is the one who uses its stomach to extend, so it can grab their prey, and the pyloric is the one who digest the food which it passes through the stomach, to the suckers and digest it on the outside with the suckers.
