37.1 - 37.7 Community + Interspecific Interactions Flashcards
Ecological Niche
the abiotic and biotic factors that relate to an organism/species
What does an ecological niche include
temperature the organisms can survive in, salinity, etc.
Competitive Inclusion Principle
no 2 species can occupy the same niche in an environment
Interspecific Interactions
interations between different species
How many types of interspecific interactions are there?
5
What are the 5 types of interspecific interactions?
1) Competition
2) Mutualism
3) Predation
4) Herbivory
5) Parasitism
In interspecific interactions, what do + and - mean
+ = good for species
- = bad for species
each sign represents one species
What + and - symbols represent competition
(-/-)
Competition
between different species for resources
Why is competition (-/-)
Bc competition can make you lose energy or lose reproductive capabilities
What + and - symbols represent mutualism
(+/+)
Mutualism
a symbiotic relationship that is beneficial for both organisms
What + and - symbols represent predation
(+/-)
Predation
good for predator because they get nutrients. bad for prey because they die
What + and - symbols represent herbivory
(+/-)
Herbivory
good for animals because they get nutrients, bad for plants because they get eaten
What + and - symbols represent parasitism
(+/-)
Parasitism
good for parasite because it gets nutrients; bad for host because they get harmed (loss of nutrition)
How many types of parasites are there
2
What are the 2 types of parasites
1) Endoparasite
2) Ectoparasite
Endoparasites
parasite that takes nutrients from inside of organisms
What is an example of an endoparasite
tape worms
Ectoparasites
parasite that takes nutrients from outside of organisms
What is an example of an ectoparasite
mosquitoes
Do parasites aim to kill their host
no, (USUALLY) bc if they kill their host they will lose their source of nutrients
Community
all populations in an area that are living
Competition ______ carrying capacity
lowers
interspecific competition vs intraspecific
Interspecific competition occurs between individuals of different species. Intraspecific competition occurs between individuals of the same species.
