Presentation transcript:

Abiotic vs. Biotic Factors Another relationship in Ecosystems What are the other relationships?

What is an Ecosystem? The living and non-living components of an environment But… What is living? What is non-living?

Biotic Factors The living or once-living components in an ecosystem. Examples: plants, animals, insects, bacteria

Still not sure???? Living things all have 7 things in common:

Characteristics of living things Growth Movement Sensitivity Nutrition Reproduction Respiration Excretion

Abiotic Factors The non-living components in an ecosystem. Examples: dirt, rocks, sand, air, rain, water

Why are abiotic factors important? Because they help the biotic factors survive. Examples: oxygen allows animals to breathe rocks help fish hide water gives fish a home

Practice

Limiting factors A factor that controls populations in its environment. ~ can be living or non-living Examples: food, shelter, oxygen, sunlight

Carrying capacity The number of organisms an environment can support
