Transcript Specie Interactions - University of Maryland Eastern Shore

Description:
Finish looking at the specific species interaction
relationships. This is in the form of a
multimedia notes/lecture period on PowerPoint.
Goals:
•Examine how interactions between a species
and its environment define a species niche.
•Explain how a species adapts to its niche.
Objectives: Day 7
I.
Explain the difference between
parasitism and predation.
II.
Describe the major types of
interactions between species

Mimicry (2 types):
•
Physical (like Octopus)
•
Chemical (for example…)

of defense or stealth
What is this?
III. Parasitism
A. Organisms who
infects a host a
means of gaining
their needs.
B. ENDO-parasite
C. ECTO-parasite
D. Require host
– Feeding
– Shelter
– Maturing

I.
Explain the difference between parasitism and
predation.
On the back of your notes:
1.
List differences between parasites and
predators.
2.
List similarities between parasites and
predators.
Think about it…
I.
Explain the difference between parasitism and
predation.
Create a class list of our comparisons and add any
that you didn’t think of to your list.
Explain in three or less sentences why parasites are
not considered predators beneath your list.
IV. Types of Relationships
• Commensalism
– One organism benefits, the other is not harmed or helped.
IV. Types of Relationships
•Competition
•Two or more organisms trying to gain the same necessities.
IV. Types of Relationships
•Mutualism
•Both organisms benefit.

II.
Describe the major types of interactions
between species
You will be assigned one of six types of species
interactions explored yesterday and today.
Working in a group of 3-4 peers you will need to
form a presentation that represents your
interaction type. Ideas include…
Ideas include but are not limited to:
•
Skit
•
•
act it out
Story-board
•
•
step by step narrative that is drawn out in stages
Song
•
sing or rap it - just make sure you don’t chicken out!
