Plant and Animals: Intraspecific relationships Flashcards
(22 cards)
Intraspecific relationship
The relationship between different species
Competition
Links with alleopathy (influences)
States of affairs in which demand for a resource exceed its supply
Mostly common in memebers of the same species - similar requirments …… Can avoid competition by exploting other resources
Harmed and harmed
Allelopathy
Links with Competition (influences) Links together with Antibiosis
Link to Allelopathy and biodiversity
Production by plants of biochemicals that inhibit the growth of competitors (a from of anitbiosis)
Biochemicals = allelochemicals
Diferent forms of allelochemicals: Negative alleopathy and Positive alleopathy
Negative alleopathy
Detrimental for tragest organism
Positive alleopathy
Beneficial for targeted organism
Niche
The sum total of an organisms requirment
Mutualism
A symbotic relationship where all species involved benefit from their interactions
helped and helped
Commensalism
A symbotic relationship between individuals of two species, where one species obtains food/ other beenfits from the other species without harming or benefiting them
Helped and unaffected
Antibiosis
Links together with Allopathy
One member of the relationship is inhibited, while the other one is unaffected
Unaffected and harmed
Explotation
When indivuals interact indirectly as they compete for common resources, like territory, prey, or food.
Herbivory, Predation, Parasitism, Carnivores
Helped and Harmed
Herbivory
Consumption of plant material by animals
Predation
One organisms kills and consumes another
Parasitism
A relationship betweem the 2 living species in which one organism is beenfitted at the expense of the other
Carnivores
Eats another animal
Stratification
Vertical relationships in space with other organisms
(Reduces interspecific relationship)
Gause’s Principle
No two species with identical ecological niches can co-exit for long in the same place
Batesian Mimicry
A species mimics the harming signals of another harmful species directed at predator
Mullerian Mimicry
One of more species develop a similar appearance. Each species is either posinous, dangerous or unpalatable to predators.
Mechanisms of defence
Physical (thorns, spines, prickles
Chemical
Links to Herbivory
Succession
Link to Allelopathy and biodiversity
Replacment of one speices by another overtime
Primary and Secondary
Primary Succession
when a new patch of land is created or exposed for the first time.
Secondary Succession
happens when a climax community or intermediate community is impacted by a disturbance.
