Description:Finish looking at the specific species interaction relationships. This is in the form of a multimedia notes/lecture period on PowerPoint.

Goals: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

Warm UpBased on the type of species interaction, where would you find the following examples on the trophic pyramid?

1. Predator

2. Prey

A =1. Consumer (Secondary & up)

2. Consumer (Primary & up except for the top consumer)

SymbiosisPredatorsA. Organism who eat

other organismsB. Secondary

Consumers and higher

C. Carnivores & Omnivores

D. Tools:– Speed– Sharp Teeth or Beak– Claws or Talons– Strength– Camouflage/Stealth– Good Senses– Group Hunting

Prey

A. Organism eaten by other organisms

B. Primary and 2nd Consumers

C. Herbivores (carnivores sometimes)

D. Tools:– Speed– Size– Poison– Odor– Good Senses– Shelter– Mimicry (2 types):

• Physical (like Octopus)

• Chemical (for example…)

Mimicry: imitating another organism as a means of defense or stealth

What is this?

III. ParasitismA. Organisms who

infects a host a means of gaining their needs.

B. ENDO-parasiteC. ECTO-parasiteD. Require host

– Feeding– Shelter– Maturing

B. ENDO-parasiteC. ECTO-parasite

D. Require host– Feeding– Shelter– Maturing– Replicating– Transport

Think about it…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.

Think about it…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!
