A characteristic that makes an individual better suited to its
environment may eventually become common in that species through a
process called ______________.natural selection
ADAPTING TO THE ENVIRONMENT

ADAPTATIONS- Behaviors and physical characteristics that allow organisms to live successfully in their environments.- Adaptations become common in a population due to natural selection.

There are three major types of interactions
among organisms:
- Competition- Predation- Symbiosis

COMPETITION
- The struggle between organisms to survive as they attempt to use the same limited resource.- Organisms compete for food, water, shelter, territory, and other resources.

PREDATIONPREDATION- An interaction in which one
organism kills another for food.
- The organism that does the killing is called the ________.predat
or- The organism that is killed is called the ____.pre

SYMBIOSISSYMBIOSIS- A close relationship between two species that benefits at least one of the species.
- The three types of symbiotic relationships are:
* Mutualism* Commensalism* Parasitism

MUTUALISMMUTUALISMA symbiotic relationship in which both
species benefit.
Black Rhinoceros/ Cattle Egret
The egret gets food
from eating bugs off the
Rhino’s back, and the rhino benefits by
getting pests removed from his
body.

COMMENSALISMCOMMENSALISM
A symbiotic relationship in which one species benefits and the other is neither
helped or harmed.
Barnacles attach themselves to
the whale allowing them
filter more water for food. The whale is not harmed or
benefited from the barnacles
presence.

This whale is rolling around on the ocean floor to remove barnacles from

PARASITISM
PARASITISM- A symbiotic relationship in which one species benefits and the other is harmed but not usually killed.- The organism that benefits is called the _______ and the organism that is harmed is called the _____.
parasite
host
Tick sucking blood from its
host.
