Share Dependence and Independence
Save to Folder
It is the mutual reliance between two or more groups.
Interdependence
It is one instance of a self-regulating balance with an ecosystem
predator-prey relationship
It is the gradual and orderly process of change in which one community is replaced by another until a stable climax community is once again established.
Succession
It is an ecosystem that supports the greatest number of species possible.
Climax community
It is something from outside the population of organisms that affect population.
Density-independent Factor
Give at least 2 example of density-independent factor
earthquakes, forest fires, floods
It is something that affects the population of organisms as a consequence of the size of population.
Density –dependent Factor
Give one example of density-dependent factor.
parasites and diseases
It occurs in barren areas where no traces of previous ecosystems remain.
Primary Succession
This succession follows a volcanic eruption in which magma erupts from a volcano and forms a completely new surface.
Primary Succession
It occurs in areas where ecosystems are destroyed by a natural or artificial disturbance, but soil remains intact.
Secondary Succession
These species that are able to move into a very new environment.
Pioneer Species
What stage of succession is this: grass, weeds, and other non-woody plants rapidly take over the bare ground?
Stage 1
What stage of succession where in bushes and young pine-tree saplings take root?
Stage 2
What stage of succession where in pine forests dominate, inhibiting undergrowth but allowing the growth of hardwood saplings?
Stage 3
What stage of succession where in the forest has reached a stable climax community state, a fully mature forest?
Stage 4
