A biology student places one end of a stalk of celery into a beaker containing a solution of red food coloring for several hours. When she removes the celery from the beaker, she notices that parts of the celery are now red. Which of the following BEST explains why this occurred?
The red food coloring moved through the stomata as a result of osmosis.
The red food coloring moved up the root hairs as a result of capillary action.
The red food coloring moved up the phloem as a result of capillary action.
The red food coloring moved up the xylem as a result of capillary action.
A biology student is investigating tropisms in plants. The student observes the response of the roots of radish seedlings to a light source placed to the right of the roots. All of the roots grow away from the light source. Which of the following tropisms is the student MOST LIKELY investigating?
gravitropism
thigmotropism
hydrotropism
phototropism
Environmental factors that affect organisms are classified as either abiotic or biotic. Which of the following lists ONLY abiotic factors that can affect organisms?
humidity, amount of carbon dioxide, and soil density
temperature, types of bacteria, and soil pH
amount of oxygen, soil salinity, and types of heterotrophs
soil nitrogen content, amount of sunlight, and types of decomposers
Decomposers, which include bacteria, fungi, and various other microorganisms, make up a special category of consumers in an ecosystem. Which of the following BEST describes the role of decomposers in an ecosystem?
Decomposers are autotrophs that convert sunlight into sugars needed by other organisms.
Decomposers produce over half of the needed oxygen for an ecosystem.
Decomposers play a vital role in breaking down plant and animal material to release nutrients needed for healthy soils.
Decomposers fix nitrogen from the atmosphere into a form that other organisms in an ecosystem can use.
A gradual change in an ecosystem over a period of time is known as ecological succession. Which of the following is the BEST description of ecological succession?
Succession is a rapid process, and all stages of development occur simultaneously.
Succession is a rapid, ordered progression.
Succession is a gradual, ordered progression.
Succession is a gradual, random process.
Many different relationships exist between organisms that are part of an ecosystem. For example, an interesting relationship exists between an African bird and rhinos. The birds follow the rhinos and eat the insects that the rhinos disturb as they amble along. The birds are helped, but the rhinos are neither helped nor harmed by this relationship. Which of the following terms BEST describes this relationship.
commensialism
mutualism
parasitism
amensalism
All organisms on Earth can be arranged into five levels of organization. Which of the following correctly organizes these levels from most exclusive to least exclusive?
biosphere, ecosystem, population, community, and species
species, population, community, ecosystem, and biosphere
biosphere, ecosystem,community, population, and species
species, community, population, ecosystem, and biosphere
A marine food web for an ecosystem in Alaska is illustrated here. Which of the following describes how energy might flow through this food web?
fox --> gull --> auklet --> zooplankton --> phytoplankton
phytoplankton --> zooplankton --> kittiwake --> rat --> fox
fox --> kittiwake --> sand lance --> zooplankton --> phytoplankton
phytoplankton --> zooplankton --> cephalopod --> puffin --> fox
Information about an ecosystem can be represented using several types of pyramids. Which of the following pyramids can NEVER be inverted?
biomass pyramids
number pyramids
both biomass pyramids and number pyramids
energy pyramids
Many types of symbiosis exists in nature. Which of the following is NOT an example of symbiosis?
predation
mutualism
parasitism
commensalism
Environmental changes such as climate changes can greatly impact an ecosystem. Which of the following is NOT an example of how climate changes could impact ecosystems?
Warming could force species to migrate to higher latitudes and altitudes.
Warming could lead to birds migrating and nesting earlier.
Warming could lead to a loss of sea ice as a habitat for particular species.
Warming could increase a species'resistance to disease.
The kangaroo rat has many adaptations that allow it to survive in its harsh desert environment. Which of the following adaptations does NOT help the kangaroo rat escape from predators?
the ability to obtain needed water from seeds
excellent hearing
large back legs
sandy fur color
Grasshoppers are insects that are members of the order Orthoptera. Grasshoppers play an important role in food webs, as they are a food source for birds. Which of the following terms BEST describes the role of grasshoppers in a food web?
producers
predators
carnivores
herbivores
