Happy Thursday Bio-Ninjas! Please READ ALL sections below! Journals: Right Page 78 Ecological Relationships Left Page 77 Relationship Examples EQ: What are the different ways organisms relate to each other in an ecosystem? Due today: Succession Menu Options Succession/Carbon/Nitrogen Packet One Day Late: (70) Succession Game Questions (turn in to box…if finished) Two days Late: (50) Three Days Late: (0) HAVE ALL HOMEWORK, LATE WORK/EXTRA CREDIT OUT READY TO BE CHECKED!

Homework check… Have Packet out We will go over a few key points During student work time I will check for completion of the packet and menu item.

ACT: Do you know enough about succession, the carbon cycle and the nitrogen cycle to move on to a new topic? What questions do you still have? What parts are you still confused about? Once we move on, what steps will you take to make sure you remember this?

PLAN: EQ: What are the different ways organisms relate to each other in an ecosystem? DO: Students will share what they produced with each other and the teacher. Students will take notes and watch videos about ecological relationships ACT: Do you know the material well enough that you can produce quality work? What questions do we still have? What am I confused about? STUDY: Students will answer teacher questions. Students will turn in Homework Students will produce their own relationship examples (Due tomorrow)

Partner work: Put the following levels of organization in order from smallest to largest: community ecosystem organism population 1. Organism (an individual living thing) 2. Population (a group of the same species in one area) 3. Community (several different populations in one area) 4. Ecosystem (all the biotic & abiotic factors in one area)

B12.A: interpret relationships, including predation, parasitism, commensalism, mutualism and competition among organisms

Resources are things organisms need to survive. Resources can be biotic. Living (food) Resources can be abiotic. Non-Living (water, sun, climate) * Write this in the bottom left of your note sheet

Adaptations and available resources affect the relationships between organisms in an ecosystem.

Adaptations are inherited characteristics that increase an organism’s ability to survive and reproduce. Adaptations can be physical. Adaptations can be behavioral.

Ecosystems are affected by three types of interactions: Competition Predation Symbiosis

Competition: when organisms attempt to use the same ecological resource One will win and one will lose. (Natural Selection/Fitness/Adaptations

Competition occurs because resources are limited! Resources Include: Sunlight Water Food Light Mates Habitats

Predation: one organism captures and feeds on another organism

Predator: kills and eats another

Prey: gets eaten

Explain what is happening in these graphs.

Predator Prey Prey Predator Both predator and prey affect the other’s population. Getting Eaten Predator Prey No Food Prey Predator

Both predator and prey affect the other’s population. When the predator population goes UP, the prey population will go DOWN (because they’re being eaten). When the prey population goes DOWN, eventually the predator population will go back DOWN (because they’re running out of food). When the predator population goes DOWN, eventually the prey population will go back UP (because they’re not being eaten as often). When the prey population goes UP, eventually the predator population will go back UP (because there is more food available).

Symbiosis: Any relationship in which two species live closely together Symbiosis literally means “living together”. There are three symbiotic relationships in nature:

Mutualism: both species benefit from the relationship  

Commensalism: one organism benefits while the other is neither helped nor harmed  =I

Parasitism: one organism lives on or in another organism and harms it  One is helped, one is harmed 

Parasite: the organism invading the other; gets its nutrients from the host Host: the organism invaded by the parasite

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

ACT: Do you feel you know the material well enough to produce quality work today? If you took a quiz tomorrow over everything we’ve covered in this unit would you be ready? If not, how will you make sure you’re ready? What questions do we still have? What am I confused about?

Eco Relationships Examples! (Left Page) Study: Eco Relationships Examples! (Left Page) Fold your paper in half. On the outside create 6 boxes. In each box, draw an original picture or meme for each type of ecological relationship (Think about how Instagram works…the picture should describe the relationships) Include a caption and hashtag that also describes the relationship #BiologyRocks #ImHungry #ParasitesRUs This is due at the beginning of class tomorrow!
