1 what are the non living parts of a woodland ecosystem
1. What are the non-living parts of a woodland ecosystem?
  • Snakes, lizards, toad
  • Air, water, light
  • Crickets, isopods, earthworms
  • Strawberries, willow trees, flowers
slide3

Non-living parts of an ecosystem are air, water, soil, rocks, and sunlight. You could also include altitude

2 which of these is a freshwater ecosystem
2. Which of these is a freshwater ecosystem?
  • Atlantic Ocean
  • Falls Lake
  • Pacific Ocean
  • Indian Ocean
slide5

Freshwater ecosystems are aquatic systems

which contain drinkable water or water of almost no salt content.

Freshwater resources include

lakes and ponds, rivers and streams, reservoirs, wetlands, and groundwater.

Salt water ecosystems are aquatic systems

that contain salt water.

All oceans are

salt water ecosystems.

3 at the nc aquarium there is a large salt water touch tank which best describes this tank
3. At the NC aquarium there is a large salt water touch tank. Which best describes this tank?
  • Large ecosystem
  • Mountain ecosystem
  • Model ecosystem
  • Tank ecosystem
4 which is these organisms make their own food
4. Which is these organisms make their own food?
  • Snakes and lizards
  • Snails and isopods
  • Plants and algae
  • Pond snails and fish
slide9

Plants are producers.

Plants produce food from the energy of the sun.

6. Which of these is a fast moving aquatic environment?
  • Aquarium
  • Meandering River
  • Mountain Stream
  • Tidal Pool

7 calvin and joe are setting up an aquarium why are they careful not to add too much elodea
7. Calvin and Joe are setting up an aquarium. Why are they careful not to add too much elodea?
  • Elodea attracts small insects.
  • Duckweed is better to add.
  • Too many of one organism can crowd the system.
  • Too much elodea turns the water green.
slide15

You can’t have too much of any plant or animal in your ecosystem, or it will crowd out the other living things.

9 when testing the ph of soil what must you do
9. When testing the Ph of soil what must you do?
  • Make sure pH paper is in the sun.
  • Make sure the pH paper is dry
  • Press the pH paper until it is moist.
  • Tape the ph paper outside of the terrarium.
10 why did we plant the seeds in the terrarium several days before we added the animals
10. Why did we plant the seeds in the terrarium several days before we added the animals?
  • Animals needed the plants for food.
  • Seeds were more important.
  • Seeds won’t grow without sunlight.
  • Animals need more space.
11 what do producers contribute to an ecosystem
11. What do producers contribute to an ecosystem?
  • They are the “clean up” crew?
  • They eat the consumers.
  • They eat small plants.
  • They make their own food and oxygen.
slide23

Producers make their own food.

Consumers

eat producers

Decomposers are the “clean up” crew.

12 which organisms recycle decaying plants and animals into something useful
12. Which organisms recycle decaying plants and animals into something useful?
  • Decomposers
  • Producers
  • Consumers
  • Trees
slide25

Scavengers eat dead

and decaying matter.

13 how do you classify animals plants and algae
13. How do you classify animals, plants and algae?
  • Ecosystem
  • Habitat
  • Model
  • Organisms (Living)
slide27

Algae

Algae

17 which of these are the only organism that can make food from non living material
17. Which of these are the only organism that can make food from non-living material?
  • Producers
  • Consumers
  • Decomposers
  • Water
18 what is the primary main energy source for all organisms
18. What is the primary (main) energy source for all organisms?
  • Decomposers
  • Producers
  • Consumers
  • Sun
slide37

The sun provides energy to producers who make their own food. Consumers eat the plants or animals that eat the plants.

19 if a plant is missing part of a leaf what might you think is happening in the aquarium
19. If a plant is missing part of a leaf, what might you think is happening in the aquarium?
  • The plant is dead.
  • An animal is eating the plant
  • The water is too cold.
  • The aquarium needs more snails.
20 how can you be sure the fish are eating the plants
20. How can you be sure the fish are eating the plants?
  • Remove some of the fish
  • Add some fish
  • Add more snails
  • Observe the fish and record what happens.
slide41

Observation and note taking is the best way to know what is going on in the

aquarium or any investigation.

21 what would you use to test the effects of acid rain in your ecosystem
21. What would you use to test the effects of acid rain in your ecosystem?
  • salt
  • baking soda
  • lemon
  • milk
slide43

Lemons are acids like vinegar.

You could use them to make a test solution.

22 what is a variable in an investigation
22. What is a variable in an investigation?
  • The thing that changes
  • The thing that stays the same
  • Writing in your science notebook
  • Your prediction
23 what is the control in an investigation
23. What is the control in an investigation?
  • The thing that changes
  • The thing that stays the same
  • What is written in your science notebook
  • None of the above
slide46

Control

What stays the

same

Variable

What changes

If you wanted to investigate the effect of acid rain, you could have two aquariums. Put an

acid solution in one, which would be the variable, and nothing in the other. That

would be the control.

24 which of these is an environmental problem
24. Which of these is an environmental problem?
  • People hunting
  • Fertilizer too close to a river
  • Bicycle lanes
  • All of the above
slide48

Environmental Problems

  • Acid rain
  • Rock salt on covered road
  • Air and water pollution
  • Fertilizer going into water sources
  • Over population of some animals
25 when you are doing an investigation what is a prediction
25. When you are doing an investigation, what is a prediction?
  • The information or data you collect
  • The focus question you are answering
  • What you think will happen
  • What you learned
27 where does oxygen come from in an ecosystem
27. Where does oxygen come from in an ecosystem?
  • Consumers
  • Producers
  • Decomposers
  • Scavengers
slide54

Oxygen comes from producers and is breathed by consumers.

Carbon dioxide comes from consumers and is breather by producers.

28 why did we let the water sit for our aquarium for a day before we added the fish
28. Why did we let the water sit for our aquarium for a day before we added the fish.

So that it would be the correct temperature.

To clean the water.

To add oxygen to the water.

Easier to move the fish.

slide56

We let the water set for 24 hours so that oxygen would be added to the

water. We could have used a plastic dropper to gently bubble air to add oxygen to the water. The fish needed oxygen in the water to breathe.

29 how do decaying plants and animals help the soil in an ecosystem
29. How do decaying plants and animals help the soil in an ecosystem.
  • It puts nutrients in the soil.
  • It removes pollutants
  • The soil stays dry
  • The soil stays moist.
30 which of the following are scavengers
30. Which of the following are scavengers?
  • Isopods and snails
  • Elodea and fish
  • Crickets and rye
  • All of the above
