4.7 Communities including abiotic and biotic factors Flashcards
An abiotic factor is
the non living part of the environment
A biotic factor
is the living part of the environment
An Ecosystem is
interactions of all the living and non living components
The two forms of competition are
intraspecific and interspecific
Intraspecific competition is
competition between organisms of the SAME speecies
Interspecific competition is
competition between organisms of DIFFERENT species
A species is
a group of similar organisms that can breed successfully and produce fertile offspring
A community is
A group of 2 or more populations of species that live in a particular area
A population is defined as
The total number of all the organisms of ONE species living in a particular area
Animals compete for
mate, water, food, territory
Plants compete for
space, water, sunlight and ions
Examples of abiotic factors include
water, sunlight, wind speed, ion content of the soil, temperature, carbon dioxide levels, oxygen levels (aquatic organisms)
Examples of biotic factors include
predation, disease, food availability, competition
Within a community species depend on each other for what..
food, shelter, pollination and seed dispersal
The relationship that is described when species in a community depend on each other is called
interdependence
