What is Ecology?
•
Ecology is the study of
relationships between living
things and between living
things and their environment.
What is an ecosystem?
•
Ecosystem is a system of living
things that interact with each
other and with the physical world.

A Biome is a collection of related
ecosystems.

An ecosystem can be as large as the

Ecosystems are more than just the
organisms they contain.
Geography,weather,climate and
geologic factors also influence the
interactions within an ecosystem.

Ecology is the study of relationships within ecosystems, where living organisms interact with each other and their environment. Ecosystems range in size from the vast Sahara Desert to small puddles, influenced by abiotic factors like water, temperature, sunlight, and more. Maintaining balance is crucial for ecosystem health, with adaptations in plants and animals playing a key role.

However.. An ecosystem can be as large as the Sahara Desert, or as small as a puddle!!! Ecosystems are more than just the organisms they contain. Geography,weather,climate and geologic factors also influence the interactions within an ecosystem.
Abiotic Factors Are nonliving physical factors of an environment. Abiotoic Factors include amount of water and oxygen, temperature, amount of sunlight and water pressure.
YOU TRY!!! YOU TRY!!! List three more examples of Abiotic Factors:
Biotic Factors Are the living, physical factors of an environment. Examples of Biotic Factors are parasitism, disease and predation.
Balance Ecosystems will fail if they do not remain in balance. No community can carry more organisms than its food, water and shelter can accommodate.
How do they stay balanced? To succeed in an ecosystem, plants and animals have special structures and behaviors called adaptations. Ex) Chameleon Polar Bear Can you think of more examples of adaptation?
