Relationships
Whats the relationship between primary and secondary succession?
One type rebuilds and the other is built from scratch.
Habitat:
The actual area in the ecosystem where an organism lives, including its abiotic and biotic resources.
What succession starts completely from scratch?
Primary
Define Pioneer species:
The first organism to grow after a dsaster.
Define Competition:
A relationship that exists between 2 or more organisms that are fighting for the same limited resource.
What type of relationship results in one organism benefiting, and the other being harmed?
Parasitism
Stable ecosystem:
One that remains relatively constant, with predictable changes.
What is the first species to grow after a disaster called?
Pioneer Species.
What are some examples of pioneer Species in primary succession?
Ferns, lichen, moss, etc.
Is it crusial in parasitism for a parasite not to kill a host?
Yes, it is very crucial.
What relationship between 2 organisms that involves close, physical, long term relationships.
Symbiosis.
Pioneer Species:
The first organism to grow after a disaster.
What would be an analogy for Primary succession.
Baking cookies from scratch.
What would be an example of secondary succession in a pioneer Species?
Weeds and grasses.
Which type of competition occurs within the same species?
Intraspecific
Which competition occurs between different species?
Interspecific
Niche:
All of the things an organism needs and does within its habitat.
What would be an analogy for a secondary succession?
Baking cookies with premade dough.
How do these organisms develop over time?
They decompose and release nutrients to form a layer of soil that larger, more complex plants can grow through.
What type of relationship involves one organism befitting and the other having no effect.
Commensalism
What relationship results in both species benefiting.
Mutualism
Keystone Species:
The species that holds the ecosystem together.
Whats the difference between the results of primary and secondary succession?
There's no difference.
What would happen once there is enough soil in a pioneer Species?
Small plants, flowers, ferns, and shrubs can begin to grow.
What is the Competitive Exclusion Principle?
No two organisms can occupy the same niche at the same time.
