Population Dynamics and Ecosystem Interactions

Explore the factors influencing population size and growth, from immigration to carrying capacity, as well as the intricate relationships between predators and prey in ecosystems. Learn about biotic and abiotic components shaping ecological interactions. Discover how prey species adapt to evade predators through camouflage and mimicry.

  1. Limiting Factors • Integrated Science Guided Notes • Powerpoint Slides • Fill in the blanks as we discuss these notes during class

  2. Changes in a ________________ size are determined by immigration, births, emigration, and deaths. Four factors affecting size immigration _________ ___________ deaths The size of a population is always changing

  3. Population growth is based on available ________ ________________growth is a rapid population increase due to an abundance of resources.

  4. ____________________ is due to a population facing limited resources Logistic vs Exponential GrowthFunny Bunnies

  5. Carrying capacity is the _____________number of individuals in a population that the environment can support.

  6. Predator Prey Relationship The predators keep the prey population under control and the size of the population of prey _________ the amount of predators an ecosystem can support.

  7. Ecosystems Have Living and Nonliving Components Abiotic Water Air Nutrients Rocks Heat Solar energy pH • Biotic • Living (or once living) • Interactions • Competition • Predator – prey • Symbiosis

  8. Major Biotic and Abiotic Components of an Ecosystem

  9. Predators Use pursuit Ambush ____________ Chemical warfare (venom) Prey Swift movement Shell Camouflage _____________ Predation 10
