B15 - Adaptation, Interdependence and Competition Flashcards
Biotic factors
Interaction of living things
Abiotic factors
Non living elements of the environment
Community
Group of interdependent living organisms in a community
Distribution
Where particular types of organisms are found within an environment
Habitat
An area where organisms live
Interdependence
When different populations rely on each other
Ecosystem
Interacting organisms and their environment
What is the best description of a stable community
Communities where the number of species and the population size stays relatively constant.
What do organisms require to survive and reproduce
Materials from their surroundings
Light intensity
Light limits photosynthesis so light intensity also
Availability of food
Plenty of food, organisms breed successfully animals struggle to survive without a lot of food and often do not breed
New predators
Organisms have no defences and will be wiped out
What are the three things animals are in competition for in the rainforest
Food
Territory
Mates
What do plants compete for
Light
Water
Nutrients
Space
Example of a plant adaptation
Leaves have a large surface area for photosynthesis
