FUNCTIONS OF LIVING THINGSAll living things need to perform basic functions such as NutritionBreathingCirculationExcretion

NUTRITION

Nutrition is the process by which living things incorporate, transform and transport nutrients in the body to form new tissue and get energy to live.

TYPES OF NUTRITION

AUTOTROPHIC ORGANISMSMake their own food by a

process called photosynthesis. PlantsSome algaeSome bacteria

HETEROTROPHIC ORGANISMS

Obtain their food from the bodies of other organisms. Herbivores Carnivores Omnivores Saprophytes Parasites

NUTRITION IN THE DIFFERENT KINGDOMS

NUTRITION IN MONERA AND

PROTISTNutrients entering through the cell membrane with the following processes

Diffusion: movement of nutrients from a area of higher concentration to a of an area lower concentration.

NUTRITION IN MONERA AND

PROTISTNutrients entering through the cell membrane with the following processes

Osmosis: movement of nutrients from an area of lower concentration to an area of higher concentration.

NUTRITION IN MONERA AND

PROTISTNutrients entering through the cell membrane with the following processesPhagocytosis: solids pass through the cell membrane.

NUTRITION IN MONERA AND

PROTISTNutrients entering through the cell membrane with the following processesPinocytosis: liquids pass through the cell membrane.

NUTRITION IN FUNGI

Their nutrition is heterotrophic.They eat other living things or dead organisms, absorbing their nutrients.

NUTRITION IN PLANTSTheir nutrition

is autotrophic.Plants perform their nutrition in three stages

AUTOTROPHIC ORGANISMSMake their own food by a

process called photosynthesis. PlantsSome algaeSome bacteria

NUTRITION IN PLANTSAbsorption of

nutrient: Absorb minerals and water from the soil through the roots. This mixture is called raw sap (savia bruta).

NUTRITION IN PLANTSThe raw sap up the xylem.

NUTRITION IN PLANTSPreparation of food:

On leaves, solar energy captured by chlorophyll, produce sugars and releases oxygen. The product is the elaborate sap (savia elaborada) and it is carried throughout the plant through the phloem.

NUTRITION IN ANIMALSAnimal nutrition is

heterotrophic.They have specialized digestive system to take and process nutrients.

HETEROTROPHIC ORGANISMS

Obtain their food from the bodies of other organisms. Herbivores Carnivores Omnivores Saprophytes Parasites

NUTRITION IN ANIMALSNutrition is

performed in three steps:Ingestion:

incorporate food through the mouth or beak.

NUTRITION IN ANIMALSDigestion:

transforms food into smaller particles and release nutrients.

NUTRITION IN ANIMALSAbsorption:

absorb nutrients and pass into the circulatory system to be carried to every cell in the body.
