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

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.
