5.1 How do species interact

Species compete for ​ (a)   , such as food, water, light, and space.

When competition for resources occurs within a single species, it is called ​ (b)   competition.

Competition among different species is called ​ (c)   competition.

• limited resources
• intraspecific
• interspecific

When 2 species compete for the ​ same resources , their ​ (a)   overlap.

The greater the overlap, the more the specie ​ (b)   for key resources.

If one species can take over the largest share of a ​ (c)   resource the competing species must move on, this is considered ​ (d)   .

• niches
• compete
• competitive exclusion
• key

If given enough time for ​ (a)   to occur, populations can develop ​ (b)   that enable them to ​ (c)   competition with other species.

​ (d)   occurs when species competing for similar scarce resources evolve specialized traits that allow them to ​ (e)   the same resources.

• natural selection
• adaptations
• reduce or avoid
• Resource partitioning
• share
