What is a dependent variable?

Autotrophic organisms [blank_start]create[blank_end] their own food.

Ingestion means to take in food.

[blank_start]Digestion[blank_end] is when food is broken down and turned into nutrients.

Examples of nutrition are:

Transport is when materials are [blank_start]absorbed[blank_end] and [blank_start]circulated[blank_end] throughout the body to cells.

Respiration occurs in the nucleus.

[blank_start]Respiration[blank_end] is the process of releasing chemicals stored in nutrients.

Synthesis is when [blank_start]simple[blank_end] substances are combined together to create more [blank_start]complex[blank_end] substances that the organism needs.

[blank_start]Excretion[blank_end] is when waste products are produced due to [blank_start]chemical[blank_end] reactions.

There are 4 types of reproduction.

Reproduction is necessary for an organism to survive.

Growth and development is when organisms increase in [blank_start]size[blank_end] and [blank_start]changes[blank_end] are made throughout their lifetime.

Regulation is all the body processes [blank_start]combined[blank_end] to maintained homeostasis. {control and coordination}

What does a unicellular organism have that carry out these life functions?

What structures does a complex, multi-cellular organism have that carry out these life functions?

Metabolism is the sum of all life processes.

Heterotrophic organisms [blank_start]ingest[blank_end] their food.
