4.1 Species Living Together

A place where an organism makes its home

• habitat

• facilitation

• niche

• biodiversity

The direct or indirect interaction of organisms that leads to a change in fitness when the organisms share the same resource

• competition

• niche

• facilitation

• biodiversity

Interactions in which one or both species benefit and neither is harmed; two types: commensalism & mutualism

• herbivory

• facilitation

• competition

• habitat

The feeding on living plant parts by animals

• carnivory

• niche

• herbivory

• omnivory

all different kinds of life (i.e. plants, bacteria, animals, and humans) that can be found in one area

• population density

• habitat

• niche

• biodiversity

An organisms place and role in an ecosystem, including where it lives and how it obtains the resources it needs to survive

• biodiversity

• niche

• competitive exclusion principle

• predation

two species cannot coexist in the same ecological niche for very long without one becoming extinct or being driven out because of competition for limited resources

• predation

• competitive exclusion principle

• population density

• biodiversity

When energy is transferred from living animal to living animal based on the behavior of a predator that captures and kills a prey before eating it

• niche

• predation

• facilitation

• herbivory

the concentration (amount) of individuals within a species in a specific geographic location

• competition

• habitat

• niche partitioning

• population density

Match the following

• Niche partitioning by plant height

• organisms occupy different spaces in the same habitat

• Spatial Niche partitioning

• organisms separate by what they eat

• Dietary Niche partitioning

• organisms separate by height

• Niche partitioning by time and grass height

• grazers eating the same grasses but at different times in the season
