100
Explain the water cycle using proper science vocabulary
Precipitation, evaporation and transpiration from plants, condensation in clouds.
100
Explain who benefits in the relationship between a flower and a bee.
Both benefit because the bee gets food and the flower has its seeds spread across the land to be replanted. This is known as Mutualism.
100
Why does the snowshoe hare's fur change to white in the winter? What is this an example of?
To blend into the snow. It is an adaptation.
100
What is the role of fungus in a food web.
It is a decomposer that breaks down dead organisms.
100
What are three reasons we need to find alternatives to fossil fuels?
Pollution, running out of them, hazardous to health, sometimes dangerous to mine (coal), cause tension between countries, etc.
200
Explain the carbon/oxygen cycle using the proper science vocabulary.
Carbon is released into the air from animal waste and pollution. Plants turn carbon into oxygen through photosynthesis. Animals breath in the clean oxygen.
200
What is an example of commensalism? How are the organisms impacted?
Answers may vary. One species must benefit and the other is neither helped nor harmed.
200
Explain why giraffes developed long necks and legs.
This is an adaptation for giraffes to reach their food in very tall trees.
200
Why would overpolulation of deer in an ecosystem be a problem?
There would not be enough food for other animals and all of the deer. Additional answers may work.
200
What are the best alternatives to fossil fuels?
Wind energy, solar energy, water energy (dams), biodeisel, etc.
300
Explain the role of decomposers in the nitrogen cycle.
Decomposers break down unusable nitrogen into usable nitrogen for plants to survive.
300
What is an example of mutualism? How are the organisms impacted?
Answers may vary. Both species must benefit.
300
What is a producer?
Plants and some bacteria that produce their own food through photosynthesis.
300
What factors limit population growth?
food, shelter, water, weather, predators
300
What products can we get from petroleum?
Gas for our cars, plastics,
400
How would burning too much coal affect the carbon/oxygen cycle.
There would be more Carbon in the air and plants would not be able to turn it all into breathable oxygen. The air would be more polluted with Carbon.
400
What is an example of parasitism? How are the organisms impacted?
Answers may vary. One species must benefit and the other is harmed.
400
What is an herbivore?
An organism that only eats plants.
400
What would be the impact on the food web if shrubs were introduced as a producer?
There would be more food for herbivores, which would increase their population. Since there would be more herbivores, there would be more secondary consumers.
400
How does a nuclear power plant protect people from radiation?
The radioactive material that fuels a nuclear power plant is contained in ceramic fuel pellets that are capable of withstanding thousands of degrees of heat. These fuel pellets are then encased in hollow metal rods that help keep the material from interacting with the water that cools the reactor. In addition, the reactor's thick metal walls and piping, as well as a massive reinforced concrete containment structure, are designed to keep the coolant, fuel, and associated radiation isolated from the environment.
500
What would happen to the Carbon/Oxygen Cycle if 50% of the Amazon Rainforest were cleared away?
There would not be enough plants to turn Carbon into Oxygen and the air would be polluted with Carbon.
500
What are the three types of symbiosis?
Mutualism, Commensalism, and Parasitism
500
What would happen to mice if the frog population decreased?
They would decrease because predators such as snakes and owls would consume more mice.
500
What is the difference between a food chain and a food web?
A food chain is a straight line from 1 producer, to 1 primary consumer, to 1 secondary consumer. A food web shows many interactions and the different ways that organisms provide energy to different organisms.
500
What are the effects of radiation on animals and people?
Possible burns and cancer.
