what is a population
number of individuals of the same species
what is a community
number of all populations in a region
what is an ecosystem
living and dead species in a region
what is a niche
the role and habitat of an organism
what is competition
the subdivision of resources that species fight for (strongest gets more resources and reproduces and creates a stronger line of kids, losers either die, adapt or move)
Competition interspecifiques
Competition with numerous species (coyote and wolf)
competition intraspecifiques
competition within a species (canola)
will there be more diversity close, or farther away from equator
closer, because of the consistency in habitat
what is a niche etendue
a bigger environement with species who are able to adapt easier, bigger populations and less species, more competition, generalistes
what is a niche restreintes
a smaller environnement with a species who isn’t able to adapt easy and is a dependant on the consistency of an environement, more biodiversity and species, less populations, less competition, specialisted
what is specialisation
is dependant on a specifique environnement to survive and if something happens to it, it will have a hard time adapting
three types of symbiosis?
Commenalisme: one benefits, one doesn’t impact paratisme: one benefits, one hurts Mutualisme: Both benefit
