Limiting Factors And Symbiotic Relationships Flashcards
Parasitism
When one spp benefits and the other gets harmed for the relationship.
Mistletoe and pine tree
Ecology
Scientific study of interactions among and between organisms and their physical environment.
Symbiotic relationships
A close, permeant association between organisms of different species.
Commensalism
On species benefits and the other isn’t harmed or benefited.
Spanish moss and tree
Community
All living things in a particular area
Populations
All members of a given species living I. A particular place at a particular time.
Exponential
Lag phase (slow growth), followed by exponential phase (time to grow), and “j” shaped
Biotic potential
Rate population would increase if every individual survived and reproduced at maximum capacity.
Logistic growth
“S” shape and happens when the population has reached the size where it can no longer support any more organisms (carrying capacity)
Competition
Space, food, water, resources, mates, and light.
Density independent
Natural disaster
Parasites
Parasites
Host vs parasite
Stress form over crowding
Too many animals in one area and it caused too much confusion
Disease
Disease spreading because of the big community size
Predator
Predator vs. prey
Moose vs wolfs
