Genes carry hereditary information

Genes are composed of DNA

Heredity is the reason children resemble their parents

Mutations change DNA code and can be passed from generation to generation

WHAT DO LIVING THINGS NEED?

EnergyNeeded to carry out life processes, like reproducing and growing

Derived from foodSome organisms make their own food (Producers)

Some organisms eat their food (Consumers)

WHAT DO LIVING THINGS NEED?

WaterLocation of many chemical reactions in living things

GasesMost animals need oxygenMost plants need Carbon dioxideSome bacteria use sulfur dioxide

WHAT DO LIVING THINGS NEED?

TemperatureOrganisms that are warm blooded must live in habitats within certain temperature range, and their bodies maintain a constant temperature

Organisms that are cold blooded must be able to change their temperature to match their surroundings

Living SpaceNeed a minimum amount of space to meet the needs above
