$ 100 C. BACTERIA…Abiotic factors are non-living, and bacteria is MOST DEFINITELY ALIVE.
Which of the following would be the habitat of a Bluejay? An oak tree A snake A: B: Sunflower seeds None of the above C: D:
$ 200 A. An Oak Tree…Habitat is where an organism lives
Which of the following is a predator of the grasshopper? Marsh grass grasshopper frog snake Carrots A frog A: B: A Hawk Marsh grass C: D:
$ 300 B. A frog. A predator is an organism that captures and feeds on another organism… in this case-the grasshopper
Click here to see an image of a lichen. What type of organism is a lichen in terms of ecological succession? A Fungus Start-up organism A: B: Dirt-breaker Pioneer Species C: D:
$ 500 D. A pioneer species is the first organism to inhabit an area. A lichen is a common pioneer species.
Which of the following is NOT a symbiotic relationship that can be found in an ecosystem? Mutualism Predation A: B: Parasitism Commensalism C: D:
$ 1,000 B. Predation…while predation is an interaction within an ecosystem, it is NOT a symbiotic relationship
A symbiotic relationship in which one organism benefits while the other is harmed is known as _________________. CLICK HERE TO SEE IT commensalism competition A: B: parasitism mutualism C: D:
$ 2,000 C. Parasitism…In the example provided, the tick feeds on blood from its host. This benefits the tick, but harms the host.
Which of the following could be a cause of secondary succession? Logging Planting trees A: B: A new species of birds being discovered. A thunderstorm C: D:
$ 4,000 A. Logging… which is a form of deforestation destroys and ecosystem and requires it to be restored.
View the images of a receding glacier by clicking HERE. Place them in the correct order that Primary succession would occur. 3,1,2 1,2,3 A: B: Primary succession cannot be caused by a receding glacier. 2,1,3 C: D:
$ 8,000 C. 2,1,3… succession shows a GRADUAL change in a community over time as seen in the example
A necessity of life such as water, sunlight, food, and space are examples of ___________. resources A: B: Biological compounds Life’s factors C: D: Details of an ecosystem.
$ 16,000 B. Resources.
A biological relationship in which two organisms live closely together is known as ____________. Succession Competition. A: B: Symbiosis Love C: D:
$ 32,000 D. Symbiosis...there are 3 types (commensalism, mutualism, and parasitism)
Which of the following would be a reason for competition among organisms? mates food A: B: Space/habitat All of the above C: D:
$ 64,000 D. All of the above… Competition occurs when organisms attempt to use the same resource at the same time.
A clown fish hides inside of a sea anemone for protection. Predators cannot get to the clown fish without being injured from the “sting” of a sea anemone. The clown fish, however, cannot be injured. The sea anemone is neither helped nor harmed. What type of symbiotic relationship is this? CLICK HERE TO SEE IT commensalism competition A: B: predation mutualism C: D:
$ 125,000 A. Commensalism…a symbiotic relationship in which one organism benefits and the other is neither helped nor harmed.
The competitive exclusion principle states that two organisms of the same species CANNOT occupy the same niche at the same time. What is the ultimate outcome of this situation? A niche has nothing to do with competition One of the two species will not survive A: B: One of the two species will move to another location Both species will learn to live along side each other C: D:
$ 250,000 B A niche is an organisms role in the environment. One of the two will NOT survive.
Why does secondary succession occur much more quickly than primary succession? The pioneer species are already present It doesn’t, primary succession occurs more quickly. A: B: Because soil is already present and it does not take as long for plants to establish themselves. There are animals present to spread the seeds for regrowth. C: D:
$ 500,000 C. It takes a very long time for pioneer species to breakdown rocks and turn into soil… therefore secondary succession occurs much faster because soil is already present.
Look at the circled portion of food chain below. Which of the following are ALL niches the grasshopper? Marsh grass grasshopper frog snake Consumer, herbivore, prey Consumer, carnivore, predator A: B: Producer, herbivore, predator. Consumer, carnivore, prey C: D:
$ 1,000,000 B. A niche is the role of an organism within an ecosystem. A niche can be related to it feeding relationships.
