Interactions and Ecosystems

Biotic vs. Abiotic Factors Biotic factors – are living components ie. animals, plants, bacteria Abiotic factors – non living components ie. water, temperature, wind, rocks

Types of Ecosystems Stations about the different types of ecosystems except Freshwater and Salt water Biomes… Still Life to review the Biomes – have to guess…tap out.. Quiz

Basic Needs for Life Food Water Gas Exchange Reproduction and Growth Waste removal Respond to Stimulus Made up of cells

Adaptations How an organism meets the basic needs for life using the biotic and abiotic components of its environment It is an inherited characteristic

Structural Adaptations Physical characteristic that helps the organism survive –Ie. wings, legs, blowhole, no limbs, ability to breathe through the skin

Behavioural Adaptations Actions that animals do to survive in their environment –Ie. migration, hunting at night, hibernation

Extreme Adaptations Ziyology Tools for the Task lab

Carbon Cycle Pretest On a blank sheet of paper, draw the carbon cycle.

Carbon Cycle Carbon is an element that makes up all living things GLqo4https:// GLqo4

Carbon Cycle Where is carbon found on Earth? –Fossil fuels – coal, oil, natural gas –Living things – carbohydrates, fats, proteins –Atmosphere – carbon dioxide –Sediment – decomposing living things –Rocks – coral reefs, limestone

Carbon Cycle What are the processes that moves carbon around? 1)Physical processes a.Water currents b.Settling to the ocean floor or to the ground c.Dissolving from the air

Carbon Cycle What are the processes that moves carbon around? 1)Chemical and Biological processes a.Respiration C 6 H 12 O 6 + O 2 = CO 2 + H 2 O b.Photosynthesis CO 2 + H 2 O = C 6 H 12 O 6 + O 2 c.Combustion = burning hydrocarbons to produce carbon dioxide

Carbon Cycles Now we will go through the Carbon Cycle Game. You are going to be a carbon atom moving through the carbon cycle. You will be moving through the stations of where carbon is located.

Carbon Cycles Make a line at each station. When it is your turn, roll the die and follow the directions of movement (or not) for that station. Record what happens for each of your rolls.

Carbon Cycles Graph your data. Go over the carbon cycle on the back of the page. Practice the carbon cycle on a whiteboard. Review the carbon cycle on a worksheet Practice the carbon cycle as a relay race in the common area.

Carbon Cycle Post –test On a blank sheet of paper, draw the carbon cycle. Carbon cycle – Mr. Parr

Nitrogen Cycle Pre test On a blank sheet of paper, draw the nitrogen cycle. Mark it using a one point checklist….

Nitrogen Cycle Nitrogen is another element that makes up living things. ekjiychttps:// ekjiyc HrOh6Qhttps:// HrOh6Q HftzpIhttps:// HftzpI

Nitrogen Cycle Where is nitrogen found? –Mainly in the protein molecules in living things –Our atmosphere – 78%

Nitrogen Cycle What are the processes that move nitrogen around? 1)Physical processes - Settling in the ocean

Nitrogen Cycle What are the processes that move nitrogen around? 2) Chemical processes -Lightening -Volcanoes -Nitrogen fixation from bacteria in the roots and ocean

Nitrogen Cycle What are the processes that move nitrogen around? 3) Biological processes -Decomposition of animal waste and dead material -Eating of plants by animals

Nitrogen Cycle Practice the nitrogen cycle –Get into 5 groups –Match the terms with the words –Use the slips of paper to make the cycle Practice using the whiteboards in the common area. Fill in the worksheet

Nitrogen Cycle Post test On a blank sheet of paper, draw the nitrogen cycle. Mark it using a one point checklist…. Mr. Parr – Nitrogen Cycle song

Symbiosis A relationship between two different species where one individual benefits

Symbiosis Mutualism – where both individuals benefit

Symbiosis Commensalism – where one individual benefits and one individual is not affected

Symbiosis Parasitism – where one individual benefits and one individual is harmed

Symbiosis Power Teaching Review cycles on whiteboards in hall Interactive website Pictionary/Charades/Headbands

Oh Deer! Let’s review what organisms need to survive. How it is cycled – hand back carbon cycle How does what an organism need affect its adaptations and its relationships? Classifying types of consumers

Roles of an organism Niche – an organism’s role and habitat in an ecosystem Eg) grass grows on the ground and makes its own food Power Teaching

Roles of an organism Why is the following not a good example of a niche? 1) A rabbit lives in a hole in the ground. YDNHTWTD

Roles of an organism Why is the following not a good example of a niche? 1)A rabbit lives in a hole in the ground. Missing the role of the rabbit ie. It eats seeds. YDNHTWTD

Roles of an organism Why is the following not a good example of a niche? 2) A bat hunts at night. YDNHTWTD

Roles of an organism Why is the following not a good example of a niche? 2) A bat hunts at night. It is missing where a bat lives ie. A bat lives in a cave. YDNHTWTD

Roles of Organisms Producers – make their own food –Also called autotrophs Power Teaching

Roles of Organisms Consumers – consume (eat) food made by the producers –Heterotrophs Power Teaching

Types of Consumers Herbivores – eat producers –Also known as “plant eaters” but not all producers are plants! –Also known as primary or first order consumers Power Teaching

Types of Consumers Carnivores – animals that eat other consumers –Can be second order or third order consumers Omnivores – animals that eat both producers and consumers Power Teaching

Types of Consumers Scavengers – eat dead or decaying plant or animal matter Decomposers – grow on dead or waste material and absorb it into their own cells and break down the rest of the material so it can be recycled back into the ecosystem Power Teaching

Types of Roles Games Matching Card Game Producer, Consumer, Decomposer Herbivore, Carnivore, Omnivore Wild Kratts Magic School Bus – Netflix Gets Eaten Watch Movie and answer questions

Roles of an organism Is the following a good example of a niche? A cactus lives in the desert and uses photosynthesis to make its own food. YDNHTWTD

Roles of an organism Is the following a good example of a niche? Bears are omnivores because they eat both meat and berries. YDNHTWTD

Roles of an organism Is the following a good example of a niche? Fish live in the water because they have gills to breathe underwater. YDNHTWTD

Interactions Show the difference between a food chain, a food web and a food pyramid due Friday June 10th –Play a food chain game –Read the textbook –Do the worksheets for Proficient…Physically represent it for Mastery
