What's one kind action you did for someone else in the past week?

​Review Questions From What We've Done So Far

​

​Hopefully this is getting easier as you go! Remember to ask questions, as this is a LESSON - not an assessment check! I want you to understand, but I am also not just giving the answers.

Multiple Select

What are some abiotic factors in this ecosystem? (select all that apply)

• Insects

• Fungi

• Sunlight and heat

• Water

• Rotting Log

Multiple Choice

What level of organization represents all the biotic factors in an area?

• Biome

• Ecosystem

• Community

• Population

Multiple Choice

What level of organization represents all the biotic and abiotic factors in an area?

• Biome

• Ecosystem

• Community

• Population

Multiple Choice

What level of organization represents distinct biological communities that have formed in response to a shared physical climate?

• Biome

• Ecosystem

• Community

• Population

Multiple Choice

Abby is walking to school with her best friend Jaylyn. They begin talking about everything they see including the ash trees, grass, weeds, ants, and people. They also notice how cold it is, how there are several large puffy clouds out, and how the sun is just starting to come up.  What level of organization are they discussing?

• community
• ecosystem
• biome
• biosphere

Multiple Choice

Jacob is going out to his grandparents fram.  On the farm is a stream that he likes to fish at. When he is fishing he sees many differernt speacies of fish as well as maple and oak trees and dragonflies.  What Jacob is seeing is an example of what level of organization?

• organism
• population
• community
• ecosystem

Multiple Choice

The study of organisms and how they interact with one another and their environment is best described as

• Biology
• Ecology
• Zoology
• Botany

Multiple Choice

The cake burned because she left it in the oven for too long.

What is the effect?

• the cake burned

• she left it in the oven for too long

Open Ended

Cause: Animals overgraze the dry grasslands that rim the desert.

What is a possible effect?

Multiple Choice

What happens when an environment reaches its carrying capacity?

• Populations will decrease
• Resources such as food, water, and space will be unlimited
• Populations will increase
• Nothing, everything will stay the same.

Multiple Choice

Food, water, sunlight, shelter, and space are resources that are  __________.

• limiting factors
• abiotic factors

• biotic factors

• part of the hydrosphere

Multiple Choice

What is the carrying capacity of the following graph?

• 1000
• 8000
• 800
• 600

Multiple Choice

What would happen if the population of hawks suddenly increased? How would it affect the other organisms in the ecosystem?

• The snakes would decrease due to more hawks eating them

• All of the population of organisms would increase

• The biotic factors in the ecosystem would increase

• The hawks predators would decrease

Multiple Choice

Which statement best explains section X?

• competition does not occur between members of different species in the same habitat

• energy is used for interbreeding between members of different species

• the population has reached the carrying capacity of its environment

• a predator recycles the remains of dead organisms

Multiple Choice

The reason that organisms cannot produce populations of unlimited size is that

• Populations always stay exactly the same.

• The resources of Earth are limited.

• There is no carrying capacity for the whole Earth.

• Species rarely compete with each other for food.

Poll

Would you rather

• Time travel to the past

• Time travel to the future

Poll

The last SRG of this unit includes the first two SRG's & asks you to ANALYZE the relationships in an ecosystem. Mark the basis subskills you feel comfortable with so far.

• Vocabulary: ecosystem, growth, organism, biome, biosphere, population, reproduction rate, community, resources, carrying capacity, limiting factors

• Organizing your observations of an ecosystem using a chart, graph, organizer

• Identifying the cause and effect

• Analyzing the relationships in an ecosystem (had you doing this a little already)

​Analyzing Tips

• Look to see if there is a trend in the data

• ​Graph on right shows how the population of people in the U.S. has increased over time

• ​Analyzing starts with just making observations of your data

Multiple Choice

First observe the graph.  Which is NOT a correct observation?

• The movie club has the most student participating

• The book club has the least amount participating

• The science club has more participating than the chess club.

• All the clubs have the same popularity.

Multiple Choice

After you make observations of a club, then you can make some inferences. Which inference is best supported by the data presented.

• Movies are better than books.

• Science is better than math.

• The movie club is more popular with students than the book club.

• Clubs are lame.

​Analyzing Tips

• When looking at data, see if there is a pattern

• Think of the bunny & grass assignment (see right), bunny population was low when grass population was high

• ​When the bunny population was high the grass was low

Multiple Choice

Can you identify the pattern ?

5, 9, 13, 17, 21, 25....

• + 2

• + 3

• + 4

• + 5

Multiple Choice

What is the main purpose of a line graph?

• to compare two things
• to show trends over time
• to have an independent variable
• so you don't have to read words

Multiple Choice

What does this trend show?

• Small town teens are lame

• 18 year olds are lame

• In general as age increases, the amount of teens living a small town having a phone increase

• In general as age decreases, the amount of teens living a small town having a phone increase

​Analyzing Tips

• ​Use the cause & effect idea to try to see how one thing affects another (Look at relationships)

• ​So if all the trees are cut down (cause) who would be affected by this (relationships)

Multiple Choice

Describe the ecosystem resources that the face mites described in the previous video prefer.

• dry skin, lots of dead skin cells

• moisture, they often migrate to your mouth

• they start on your face & then migrate to your belly button

• oily skin, lots of dead skin cells

Open Ended

What do you hypothesize might best reduce the population size of face mites?

Antibiotics are medications taken with the intention of killing off the bad bacteria that are making you ill. Unfortunately they also kill the good bacteria. What effect do you think this might have?

Multiple Choice

What is one way that our microbiome does NOT help us?

• Helps us digest our food

• Helps our immune system fight the bad guys

• Creates needed vitamins

• Trick question - our microbiome is bacteria, and all bacteria should be killed

How might this Spotted Lantern moth affect one organism in our ecosystem?

How will then affect other organisms in our ecosystem?

The End​ - Your To Do List

1. 1. Retake if you scored below a 85% - This will give you at least a 2 on this SRG

2. ​Look up your grades on SYNERGY - if you haven't turned in the outdoor observation ECPO assignment (out of 100%) please work on this next

3. ​Check teams if you have been absent to catch up on old assignments

4. ​Work on your table's minecraft biome
