Page 2: Carrying Capacity:

Carrying Capacity:

• Maximum population of a given species that can survive indefinitely in a given environment

Depends on:

• Conditions & resources available in habitat

• Resource consumption by species

Resources & Conditions Present:

• Sunlight

• Rainfall/Moisture

• Climate

• Soil type

• Space

• Landscape/Terrain

• Food sources

• Predator levelshttp://danieldamianiphoto.files.wordpress.com/2012/07/img_5429.jpg

• Changing conditions (resource availability) and/or

• Changing resource use by species

• Natural & Human influence

Page 7: Carrying Capacity:

Overshoot: More individuals of a species

living in an area than can be supported over a long time.

Carrying Capacity Overview:

• Defined as a sustainable population level for a species within an environment

• Influenced by abiotic (non-living) and biotic (living) factors

• Connecting resource use & availability with population
