The primary focus of all biological studies is understanding the world of living things and how they react.
UNDERSTANDING LIVING THINGS

The study of biology includes the investigation of interactions among species.
ALL LIVING SPECIES INTERACT WITH ONE
ANOTHER

By studying biology, you can better appreciate the great diversity of species on Earth and the way each species fits into the dynamic pattern of life on the planet
EVERYONE BENEFITS FROM THE STUDY OF
BIOLOGY

INTERACTIONS OF LIFE Living things do not exist in isolation There is a delicate balance in nature Living things depend on other living and non-
living things

All living things depend on other living things for their existence; all living things play a part in the delicate balance of life.
LIVING THINGS DO NOT EXIST IN
ISOLATION

CHARACTERISTICS OF LIVING THINGS Organization – an orderly structure – basic unit is
cell Reproduction – produce offspring Growth – increase in living material, new structures Response to Stimuli – interact with their
environment Maintain Homeostasis – regulate their environment Obtain and use materials – energy As a group they evolve – changing over time

CHARACTERISTICSOF
LIVING THINGS14
To be considered living, something must exhibit all of the characteristics of life.
Organism is another word for living thing.
Every living thing, single-celled organisms to complex, multicellular plants and animals, is made up of parts that function together in an orderly living system.
