Essential Question
PG 131
What are some relationships
between different species beyond
food chains?
Standard
B.12A - interpret relationships, including predation,
parasitism, commensalism, mutualism, and competition
among organisms.
The three types of community interactions that
can affect an ecosystem are:
• Competition
• Predation
• Symbiosis
Competition occurs when organisms of the
same or different species attempt to use the
same ecological resource.
A resource refers to any necessity of life.
•
•
•
•
•
Water
Nutrients
Light
Food
Space
Some resources are limited
Limiting Factors
• If the presence or absence of a factor limits the
growth of the ecosystems elements, it is called a
limiting factor .
• One of the features of an ecosystem is that its
growth is limited under normal conditions by
competition for resources within the system and
by external factors such as environmental
changes
Different factors can limit population growth
How is the population size affected by these
factors?
Carrying Capacity
• The largest number of individuals of one
species that an ecosystem can support OVER
TIME.
• If a population begins to exceed the
environment’s carrying capacity, some
individuals will not have enough resources.
–The could die or be forced to move elsewhere.

Predation
An interaction in which one organism captures
and feeds on another organism is called
predation.
The organism that does the killing and eating is
called the predator.
The food organism that gets eaten is called
the prey.
An adaptation is an inherited characteristic
that increases an organism’s ability to survive
and reproduce.
• Adaptations can be
physical.
• Adaptations can be
behavioral.
List 3 examples of physical and behavioral adaptations.
Any relationship in
which two species live
closely together is
called symbiosis.
Symbiosis literally
means “living
together”.
In mutualism, both species benefit from the
relationship.
In commensalism, one member of the
relationship benefits while the other is neither
helped nor harmed.
In parasitism, one organism lives on or inside
another organism and harms it.
“1 benefits and 1 is harmed”
The parasite obtains
all or part of its
nutritional needs
from the other
organism, called the
host.
Parasites do not
usually kill their hosts.

Standard
B.12A - interpret relationships, including predation,

Examples of Relationships:
In the following clips identify the relationship that is shown
• 3 kinds of symbiosis : Clownfish/Anemone,
Fish lice, Cleaner Fish, Shark/Remora
• Cleaner Fish and Tiger Groupers
• Nile Crocodile
• Rhino and bird (symbiotic song)
• Bird and Capybara & Hippo and Bird
• Bonus: 5 most horrible parasites
Eco Relationships “Instas”
• Divide your paper to create 4
boxes.
• In each box, draw an “insta”
for each type of ecological
relationship (Think about how
Instagram works…the picture
should describe the
relationships)
• Predation, Mutualism,
Commensalism, and Parasitism
• Include a caption that also
describes the relationship
