Unit 1: Interaction of Living Things Plus: Highest Tide

Bell Work In your Cornell notes draw a T-chart comparing Biotic and Abiotic factors. Abiotic Factors: Affect the ability of organisms to survive, reproduce; help determine types and numbers of organisms able to exist in environment; limiting factors restrict growth. Biotic Factors : Living things that directly or indirectly affect organisms in environment; organisms, interactions, waste; parasitism, disease, predation.

Part I: Everything is Connected

Studying the Web of Life One example of interaction between organisms is that they eat each other. Work with your tablemate to: List 10 other ways in which organisms interact.

Studying the Web of Life Ecology is the study of the interactions of organisms with one another and with their environment An environment is divided into two groups: Biotic —all organisms interact with other organisms Biotic —all organisms interact with other organisms Abiotic —organisms interact with nonliving parts of the environment Abiotic —organisms interact with nonliving parts of the environment

Studying the Web of Life With your tablemate, make a T-chart listing all the biotic and abiotic interactions you can from the picture. With your tablemate, make a T-chart listing all the biotic and abiotic interactions you can from the picture.

Organization in the Environment Levels of the Environment Level 1: Individual Organism Level 2: Population : a group of organisms of the same species that live in a specific geographic area Level 3: Community: all the organisms of species that live in a habitat and interact with one another Level 4: Ecosystem: a community of organisms and their abiotic environment Level 5: Biosphere : the part of the earth where life exists

Lab Activity 1.Each lab group will receive an organism. 2. For this organism you are to choose and create an environment, such as swamp, forest, etc. 3.Within this environment you are to illustrate each level. 4.Title the environment. 5.Label each level. 6.Put your names on the poster 7.Hang your posters in the hallway.

Homework Complete the worksheet given to you by your teacher. Be sure to put your name on it. DUE TOMORROW!

Living Things Need Energy Bell Work: List the major group of plants.

The Energy Connection Producers: Organisms that use sunlight directly to make food Mostly plants but also algae, bacteria and plankton Mostly plants but also algae, bacteria and plankton Identify the main producers in the following ecosystems: Identify the main producers in the following ecosystems: Prairie Prairie Forest Forest Beach Cordgrass Beach Cordgrass

The Energy Connection Using the computers define the terms from the bell work and explain their role as producers. Find the links on the table at: BandwidthOregon.com Nonvascular Plants Seedless Vascular Plants GymnospermsAngiosperms

Use a Computer Bell Work: Write the questions and answers in your notebook. What is an ecosystem? What does it include? In an ecosystem, each organism has its own _______ or role to play. What can you find in a small puddle? What are the five basic needs of living things? What are the foundations of the wonderful world of life? What can be disastrous for an ecosystem? Why? List four threats to ecosystems. Food Webs and Pyramids eschooltoday.com/ecosystems/ecosystem- trophic-levels.html

Food Webs and Pyramids Bell Work Answers All living things in a given area interacting with each other an the abiotic world All living things in a given area interacting with each other an the abiotic world It includes plants, animals, organisms, weather, earth, sun, soil, climate, and atmosphere It includes plants, animals, organisms, weather, earth, sun, soil, climate, and atmosphere Niche Niche in a small puddle you can find microorganisms, insects, plants in a small puddle you can find microorganisms, insects, plants Sunlight, water, air, food, and temperature Sunlight, water, air, food, and temperature

Food Webs and Pyramids The foundations are energy flow and recycling of nitrogen and carbon The foundations are energy flow and recycling of nitrogen and carbon An external factor, like a change in temperature, can be disastrous for an ecosystem An external factor, like a change in temperature, can be disastrous for an ecosystem Four threats to ecosystems are absence of one member or one abiotic factor; fires, floods, storms, volcanic eruptions, and human activities Four threats to ecosystems are absence of one member or one abiotic factor; fires, floods, storms, volcanic eruptions, and human activities

The Energy Connection Consumers: They get the energy of the sun by eating other organisms Herbivore : eats only plants Herbivore : eats only plants Carnivore: eats only animals Carnivore: eats only animals Omnivore: Eats both plants and animals Omnivore: Eats both plants and animals Give examples of each type of consumer.

The Energy Connection Scavengers: Omnivores that eat dead things Decomposers: Organisms that break down dead organisms; for example, bacteria and fungi Decomposers are important because they are nature’s _____________________. Using the computers, research scavengers and decomposers to answer the blank and explain why they are important.

Energy Connection Bell Work Copy the analogies and fill in the blanks. 1.A herbivore is to a consumer as a student is to a ________________. 2.A decomposer is to the environment as a garbage man is to a _________________. 3.Energy flow is to ____________ as the foundation is to a building.

Food Webs and Pyramids Use a Computer define the following terms and give examples of each: Trophic levelsTrophic pyramid Primary producer Nematodes Primary consumer Arthropods Secondary consumerProtozoa Tertiary consumer How much energy is transferred at each level?

Energy Connection Bell Work 1.On the back or bottom of your worksheet, make a list of5-10 things you know about cockroaches. 2.Be prepared to validate them as True or False based on the video.

Food Webs and Pyramids eschooltoday.com/ecosystems/ecosystem- trophic-levels.html Use a computer In your Cornell notes: identify the individual species in the community. Create a pyramid that places these organisms in primary producer, primary consumer, secondary consumer, and tertiary consumer categories.

The Energy Connection Food Chains and Food Webs Food chain: the pathway of energy transfer through various stages as a result of the feeding patterns of a series of organisms; follows one line Food Web: a diagram that shows the feeding relationships between organisms in an ecosystem

The Energy Connection Energy moves from one organism to the next in a one way direction Energy moves from one organism to the next in a one way direction Organisms store energy they don’t use Organisms store energy they don’t use Only the stored energy is passed on to the next organism Only the stored energy is passed on to the next organism Two main food webs are aquatic and land Two main food webs are aquatic and land Draw a location from a hat. Use the computers research and to create a food web for that location.
