life processes
The basic and essential functions or process performed by livin' organism to maintain life
Nutrition
The process of obtaining and utilising of food
Respiration
The process of breaking down of food to obtain energy
Transportation
The process of transfer of substances from one part of the body to another parts
Excretion
The process of removal of waste materials produced in the cell of the body
Mood of nutrition
Autotrophic nutrition
Heterotrophic nutrition
Autotrophic nutrition
The orgrainms make it own food from simple inorganic materials.
Heterotrophic nutrition
Give reason cannot make or synthesize it food from simple inorganic materials
Photosynthes
* Organisms Autotrophic organisms, primarily green plants (also algae, cyanobacteria).
* Energy Conversion: Light energy to chemical energy.
* Chemical Energy Form: Glucose (sugar)
* Inorganic Raw Materials: Carbon dioxide (CO_2) and water (H_2O)
* Location: Chloroplasts (within plant cells)
* Energy Source: Light (from the sun)
* Vital Byproduct: Oxygen (O_2)
* Overall Purpose: To produce food (glucose) for the organism and release oxygen into the atmosphere.
Photosynthesis Equation:
6CO_2 + 6H_2O + \text{Light Energy} \rightarrow C_6H_{12}O_6 + 6O_2
Where:
* CO_2 = Carbon Dioxide
* H_2O = Water
* C_6H_{12}O_6 = Glucose (a sugar)
* O_2 = Oxygen
Where does mechanical and chemical digestion begin?
In the mouth. Mechanical digestion is chewing; chemical digestion starts with salivary amylase breaking down starches.
What happens to food in the stomach?
Food is churned (mechanical digestion) and mixed with hydrochloric acid and pepsin (chemical digestion) to break down proteins into smaller pieces, forming chyme.
What is the primary role of the small intestine?
: It's the main site for chemical digestion of all food types and the primary location for nutrient absorption into the bloodstream.
What are the roles of the pancreas and liver (via gallbladder) in digestion?
The pancreas releases enzymes (for carbs, proteins, fats) and bicarbonate. The liver produces bile, stored in the gallbladder, which emulsifies fats in the small intestine.
What is the main function of the large intestine?
To absorb water and electrolytes from the remaining indigestible food matter, forming and storing feces before elimination.

What is the role of digestive enzymes?
Nutrients like carbohydrates, fats, and proteins are broken down into smaller molecules that can be absorbed by the body.
