4. Question Column 1-200
Goby species live among the spines of toxic sea-urchins Goby gain protection from the sea urchin. The sea urchin is neither advantaged nor disadvantaged by the relationship.
Identify the type of symbiosis.

5. Answer Column 1-200
Commensalism

6. What is a mite and what does it do?
Question Column 1-300
What is a mite and what does it do?
What type of symbiosis is shown?

7. A mite sucks the blood of its host Parasitism
Answer Column 1-300
A mite sucks the blood of its host
Parasitism

8. Question Column 1-400
The Boxer crab carries a pair of small anemones in its claws. When approached by a predator it waves these around presenting the stinging tentacles so as to deter the marauder. The anemones benefit from the small particles of food dropped by the crab during feeding.
This is an example of mutualism. How does the crab benefit? How does the sea anemone benefit?

9. Answer Column 1-400 Crab – benefits be scaring away predators
Sea Anemone – benefits by gaining food dropped
by the crab
It’s a WIN-WIN!

10. Question Column 1-500
Egrets hang out with large animals, such as hippos and rhinos. When those big beasts walk, their feet stir up insects and other small animals on the ground. That means the egret doesn't have to look far for a meal.
This type of symbiosis is commensalism. Therefore, what can you infer about the hippos or rhinos role in the relationship?

11. The hippo or rhino would be unaffected!
Answer Column 1-500
The hippo or rhino would be unaffected!

12. Question Column 2-100
What is the role of a plant? What organisms is always at the beginning of a food web or food
chain?
Consumers
Producers
Decomposers
Scavengers

13. Answer Column 2-100
Producers

14. During photosynthesis, plants make what?
Question Column 2-200
During photosynthesis, plants make what?

15. Answer Column 2-200
Food and oxygen

16. Question Column 2-300 The products of photosynthesis are…
Carbon dioxide and oxygen
Oxygen and sugar
Sunlight and carbon dioxide
Water and chlorophyll

17. Answer Column 2-300
b. oxygen and sugar

18. Question Column 2-400
What is the definition of photosynthesis? Why is it important? What would happen if there were not producers?

19. Answer Column 2-400
Photosynthesis is the process of using sunlight to make food for plants.
We need plants/producers in order to survive. If we had no plants animals and humans would not survive.

20. Question Column 2-500
How do carnivores get their energy from plants? Give an example of a food chain to show the flow of energy.

21. Answer Column 2-500
When herbivores eat plants, they receive some of the energy that plants make. Then, carnivores receive some energy from herbivores when the carnivores eat the herbivores.
Grass Rabbit Fox Fungi
Sun provides energy to the producer which is the grass. The rabbit is a herbivore and eats only producers so it receives energy from the grass. The fox is a carnivore so it receives energy by eating the rabbit. Lastly, the fungi gets energy because it eats the fox and returns the nutrients back to the soil.

22. Question Column 3-100 What group of organisms aid
in the process of composting?
Why do they help?

23. Answer Column 3-100
Decomposers!
Return nutrients
to the soil

24. Why do we have less energy during the winter months?
Question Column 3-200
Why do we have less energy during the winter months?

25. Less hours of sunlight= less energy for plants
Answer Column 3-200
Less hours of sunlight= less energy for plants

26. What does composting put back in the soil?
Question Column 3-300
What does composting put back in the soil?

27. Answer Column 3-300
nutrients

Prairie dog
grass, flowers
Rabbit
Wolf
Hawk

42. Question Column 5-100 Identify one synonym for the word beneficial.
Identify one synonym for the word detrimental.
Which role in a food chain uses photosynthesis to make food?

43. Answer Column 5-100 Plants use photosynthesis to make food Beneficial
Detrimental
good
bad

injurious
Plants use photosynthesis to make food

44. Question Column 5-200
What would happen if frogs were taken out of this food chain? What effects would it have?
Algae -> insect -> frog-> snake
If we added in dragonflies into
This food chain what would
Happen to the frog population?

45. Answer Column 5-200 Algae -> insect -> frog-> snake
If frogs were taken out of this food chain the insects would increase and overpopulate and the snake population would decrease/die out because it would not have a food source of the frog.
If dragonflies were added in the frog population would increase.

48. Question Column 5-400
Zebra mussels first came to the U.S. from Eurasia in ship ballast water released into the Great Lakes. Since 1988, they have spread dramatically, out-competing native species for food and habitat. Zebra mussels can attach to almost any hard surface - they clog water intake and discharge pipes, attach themselves to boat hulls and docks, and they even attach to native mussels and crayfish. How as the Zebra mussels affected the ecosystem?
