What is Populations?
Disturbance is so severe that no vegetation of soil life remains causes this type of Succession
What is Primary Succession?
The Type of Relationship where both organisms benefit
What is Mutualism?
Number of individual organisms present in a given population and given time
What is Population Size?
Organisms that get their energy from nonliving resources, meaning they make their own food
What is Autotrophs?
Level that includes all life
What is Biosphere?
Species that colonize the newly exposed land first
What is Pioneer Species?
Type of relationship where one organism benefits and the other organism has no effect
What is Commensalism?
Number of individuals within a population per unit area
What is Population Density?
Organisms that are consumers that get their energy by eating other organisms
What is Heterotrophs?
The interaction of living and nonliving things in an area
What is an ecosystem?
Disturbance that does not destroy all living things or soil causes this type of Succession
What is Secondary Succession
Type of relationship where one organism benefits and the other is harmed
What is Parasitism?
Describes how organisms are arranged within an area
What is Population Distribution?
Plant only eating organism
What is Herbivores?
Specific environment in which an organism lives
What is a Habitat?
Stable community that completes the succession process
What is Climax Community?
Individual organism that hunts, captures, kills, and consumes prey
What is a Predator?
The Three types of population distribution
What is Random, Uniform, and Clumped?
Group of consumers that break down organic matter into simpler compounds found
What is Decomposers?
Group of individuals that interbreed and produce fertile offspring
What is the Definition of Species?
Pioneer Species that form mutualistic relationship between algae and fungi that break down bare rock
What is Lichens?
Two species evolve in response to changes in each other
What is Coevolution?
The departure of individuals from a given area
What is Emigration?
Level of consumer that is a carnivore that eats other carnivores
What is Tertiary Consumer?
