NUTRITION

Getting food & changing it into a usable form

• Nutrients are substances used for energy, growth, & repair

Autotrophs - Make their own food / nutrients

• Producers include - Plants, algae, & some bacteria

Heterotrophs - Eat other organisms for nutrients

• Consumers include animals, fungi, & some bacteria

• Consumers must ingest, (take in) digest, (breakdown) then egest (remove) their food

TRANSPORT

Moving materials from one place to another in a cell / organism

RESPIRATION

Process / reaction to make energy (ATP) in a cell aka cell respiration

• ALL living things use respiration to get energy

EXCRETION

Getting rid of CELL wastes from the cell or organism

GAS EXCHANGE

Take in oxygen, (for respiration) & remove carbon dioxide (cell waste)

SYNTHESIS

To BUILD or to MAKE large, complex molecules from small, simple ones

REGULATION

The CONTROL & COORDINATION of the life processes

GROWTH

Increase in the size &/or the number of cells in an organism; often accompanies development

REPRODUCTION

Adding members to your own species

• The only life process an individual doesn’t need to survive

Asexual reproduction - 1 parent ; offspring identical to parent, cloning

Sexual reproduction - 2 parents ; offspring NOT identical to parents

METABOLISM

The sum of all life processes

Ex. of metabolic activities

• Cell respiration, digestion of food, synthesis of new cells

HOMEOSTASIS

Maintaining a constant internal environment

• DYNAMIC EQUILIBRIUM
