Which term best defines this organization: All the organisms/ species living in a particular area
and the physical components with which the organism interact... - (answer)Ecosystem
I design an experiment to test whether or not fertilizer has an effect on the growth of dandelions.
My hypothesis is that dandelions in soil to which fertilizer is added, will produce more biomass.
What is my independent variable in this experiment? - (answer)Presence or absence of fertilizer
What is an example of Aposematism? - (answer)A bright red beetle sitting on a green leaf.
A black and yellow stinging wasp that buzzes as it flies.
Which model of natural selection is being exerted in the following scenario: In a population of
fish adult body size is a variable trait (with a normal distribution). The smallest adult fish are
cannibalized by their cohorts and the largest adult fish are visible to a bird predator and tend to
be preyed upon frequently. - (answer)Stabilizing
Which mode of natural selection is being exerted in the following scenario: In a population of
plants resistance to a type of fungal blight is a variable trait (with a normal distribution). The
blight kills 80% of the plants, leaving only the most resistant to survive. - (answer)Directional.
,Which abiotic factor(s) is/are responsible for the presence of different seasons on our planet? -
(answer)The Earth's tilt.
Which biome is comprised of a productive area where rivers meet the ocean? - (answer)Estuary
Which key abiotic climate factor(s) distinguish terrestrial biomes? - (answer)Precipitation and
Temperature
Which biome does not include fire as a natural part of its cycle? - (answer)Coniferous forest.
In the figure above, which biome is represented by "e"? - (answer)Coniferous forest
In the figure above, which biome is represented by "d"? - (answer)Broadleaf forest
In the figure above, which biome is represented by "a"? - (answer)Desert
Bark beetles feed under the bark of trees (bark beetles and trees) - (answer)Herbivory
,Beetles carry mites with them; the mites disembark at a food source and prey on maggots which
are the beetle's competitors (mites and beetles) - (answer)Mutualism
Beetles carry mites with them; the mites disembark at a food source and prey on maggots which
are the beetle's competitors (mites and maggots) - (answer)Predation
Osprey and grizzly bears both feed on salmon as they run upstream (Osprey and Salmon) -
(answer)Predation
As the seeds of day lily fall to the ground Harvester ants carry them off to their burrows for food
(ant and lily) - (answer)Herbivory
The relationship between coral and dinoflagellates (from your book) - (answer)Mutualism
What does "the rule of tens" tell us about energy passing through a food chain? - (answer)That
90% of the energy is lost at each trophic level
Which forms of Carbon, Phosphorus, and Nitrogen are usable to plants? - (answer)Carbon
dioxide, Phosphate ions and Ammonium.
, Which elements have abiotic reservoirs in the Earth's atmosphere? - (answer)Nitrogen and
Carbon.
What is measured in the context of Net Primary Production? - (answer)Biomass/area/time
This graph (above) represents the mean number of times (+- standard error) that hissing
cockroaches choose oranges vs. bananas as a preferred food type. What can you conclude about
this experiment? - (answer)There is no significant difference in food preferences
What do the little black bars on the top of each column on the graph, represent? - (answer)The
variation around the mean.
How is nitrogen made available to plants? - (answer)Nitrogen fixing bacteria turn the
atmospheric Nitrogen into usable ionic forms
Which type of dispersion pattern might you expect to see in a population of individuals that
exhibit territorial behavior when interacting? - (answer)Uniform
