Interdependence in Ecosystems
Main Science Concept
Explain how biotic and abiotic factors affect the carrying capacity and sustainability of an ecosystem
Identifies and describes how biotic and abiotic factors (e.g., available resources, disease, competition, predation, climate, habitat) affect the health and carrying capacity of an ecosystem.
Review What are biotic and abiotic factors?
Biotic:▪ Competition▪ Disease▪ Human Impact▪ Predation
Abiotic:▪ Climate▪ Temperature▪ Rain▪ Habitat▪ Resources
Competition
Food and Space Limits population
size Most intense
competition is among individuals of the same species because they need the same kinds of food and shelter
Populations
Groups of organisms that are all the same species
Limiting Factor
Anything that restricts the number of individuals in a population
Include living and non-living features of the ecosystem
Can affect more than one population in a community
Carrying Capacity Largest number of
individuals of one species that an ecosystem can support over time
If a population exceeds the environment’s carrying capacity, some individuals will not have enough resources.
They could die or be forced to move.
Sustainability
Living systems remain diverse and productive over time
Using resources so that they are not depleted or permanently damaged
What abiotic or biotic factors could affect carrying capacity and sustainability of your ecobottle?
