  1. Interdependence in Ecosystems

  2. 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. 

  3. Review • What are biotic and abiotic factors? • Biotic: • Competition • Disease • Human Impact • Predation • Abiotic: • Climate • Temperature • Rain • Habitat • Resources

  4. 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

  5. Populations • Groups of organisms that are all the same species

  6. 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

  7. 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.

  8. Sustainability • Living systems remain diverse and productive over time • Using resources so that they are not depleted or permanently damaged

  9. What abiotic or biotic factors could affect carrying capacity and sustainability of your ecobottle?
