ECOLOGY AND THE ENVIRONMENTAn Introduction
ECOLOGY The study of how organisms interact with one
another and with their environment (surroundings).
BIOTIC FACTOR
A living thing (organism).Animals, Plants,
Unicellular Organisms.
ABIOTIC FACTOR
A non-living thing. Water, Soil,
Sunlight, Rainfall, Temperature
LEVELS IN THE ENVIRONMENTBIOME
ECOSYSTEM
COMMUNITY
POPULATION
ORGANISM/SPECIES
An ORGANISM is a living thing.
A SPECIES is organisms that are closely related and can produce offspring that can produce more offspring.
ORGANISM/SPECIES ORGANISM/SPECIES
This alligator is an organism from the American Alligator species.
POPULATION
A POPULATION is a group of organisms from the same species that live together in the same living space. The organisms in a
population often compete for shelter, food, and water
POPULATION
ORGANISM/SPECIES
This is a population of alligators.
COMMUNITY
A COMMUNITY is all of the different populations that share the same living space. They also compete for
many things such as shelter, food, and water.
COMMUNITY
POPULATION
ORGANISM/SPECIES
This is a community of alligators, cranes, and grasses.
ECOSYSTEM
An ECOSYSTEM is all of the communities that share the same living space and the abiotic factors (non-living things) in the environment.

ORGANISM/SPECIES
This is an ecosystem of alligators, cranes, and grasses all living in a murky pond.
BIOME
A BIOME is made up of many ecosystems that share similar climate and communities.

ORGANISM/SPECIES
The freshwater biome is made up of many smaller ecosystems: ponds, lakes, rivers, and streams.
BIOMES VS ECOSYSTEMS Biomes contain many ecosystems. All of the ecosystems within a biome share
most of the same traits: Abiotic: Temperature (cold, hot, or varied) Abiotic: Rainfall Abiotic: Soil and Rock types Biotic: Plants and Animals adapted to the climate.
ExampleBiome: ForestsEcosystems: Amazon Rainforest, African Rainforest, Australian RainforestAbiotic and Biotic Factors are similar in different parts of the
world because they are in the same biome.
