Which term best defines this organization: All the organisms/ species living in a particular area
and the physical components with which the organism interact...
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?
Presence or absence of fertilizer
What is an example of Aposematism?
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.

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.
Directional.
Which abiotic factor(s) is/are responsible for the presence of different seasons on our planet?
The Earth's tilt.
Which biome is comprised of a productive area where rivers meet the ocean?
Estuary
Which key abiotic climate factor(s) distinguish terrestrial biomes?
Precipitation and Temperature
Which biome does not include fire as a natural part of its cycle?
Coniferous forest.
In the figure above, which biome is represented by "e"?

In the figure above, which biome is represented by "d"?
Broadleaf forest
In the figure above, which biome is represented by "a"?
Desert
Bark beetles feed under the bark of trees (bark beetles and trees)
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)
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)
Predation
