B16(Adaptation, Interdependence And Competition) Flashcards
What is an ecosystem
The interaction of a community of living organisms with the non living parts of their environment
What does biotic mean
Living
What does abiotic mean
Non living
What is interdependence
-Within a community each species depends on other species
-if one species is removed it can affect the whole community
What is a community
Communities are made up of the different species of animals, plants, Protista , fungi,bacteria and archaea that are all interdependent in a habitat
What is a stable community
Where all the species and environmental factors are in balance so that population sizes remain fairly constant
What are the abiotic factors that affect communities
-light intensity
-temperature
-moisture levels
-soil PH and mineral content
-wind intensity and direction
-carbon dioxide levels for plants
-the availability of oxygen for aquatic animals
What are the biotic factors affecting communities
-availability of food
-new predators arriving
