Succession
succession occurs in areas where no
well developed soil exists
What is Primary (Sucession)?
Lichens and
mosses
What are Pioneer Species?
protective coloration in which an animal resembles its
background.
What is Camouflage?
A eagle hunting a mouse.
What is Predation?
starts on lifeless substrate
What is Primary Succession?
Gradual establishment of an ecosystem
where one did not exist before
What is Primary Succession?
Middle stages of primary succession are
dominated
What is Intermediate Species?
an interaction between two organisms that are
using the same limited resource.
What is Competition?
A tick feeds on the blood of its host and may carry disease
What is Parasitism?
starts where soil remains and some life persists
after disturbance
What is Secondary Succession?
Gradual change in species occupying
an area, due to changes in 1 or more
abiotic or biotic factors favoring some
species over another.
What is Succession?
Plant or animal species that are the
first to occupy a newly exposed or
disturbed area.
What are Pioneer Species?
Any interaction between two organisms in which
one organism (the predator) consumes all or part of another organism (the prey).
What is Predation?
The flower lives on a tree and absorbs the water from runoff and the tree is unaffected.
What is Commensalism?
introduced AND causes ecological/economic/human
harm.
What is an Invasive Species?
Gradual reestablishment of an
ecosystem from an area where it
previously existed.
What is Secondary Succession?
Pioneer Species
What are Lichen & Fungi?
symbiotic relationship where one organism is harmed and the other is helped
What is Parasitism?
a symbiotic relationship where one organism benefits and the second is neither harmed nor helped.
What is Commensalism?
Deforestation, Habitat Loss, Runaway Fertilizer Runoff, and Uncontrolled Introductions are examples of?
What are Negative Human Impacts?
Last stage of succession.
What is Climax?
an intimate relationship between different species
in which at least one species depends upon the relationship to
survive.
What is Symbiosis?
a symbiotic relationship where both organisms are helped in some way.
What is Mutualism?
An ant protects a caterpillar from predators and the caterpillar produces a sweet liquid for it to drink.
What is Mutualism?
Higher species diversity generally increases resilience and
stability.
What is Biodiversity or Ecosysytem Sustainability?
