Base your answer to the following question on the diagram below and on your knowledge of biology.
The diagram represents some processes occurring in the leaf of a plant.
Which statement best describes animals that are heterotrophs?
They are able to convert light energy into useful chemical bond energy.
Which equation illustrates a process of nutrition carried out within the leaf?
A + C A + B + D
As the depth of the ocean increases, the amount of light that penetrates to that depth decreases. At about 200 meters, little, if any, light is present. The graph below illustrates the population size of four different species at different water depths. Which species most likely performs photosynthesis?
B
Which phrase, if placed in box X, would correctly complete the flowchart shown below?
Increased concentration of glucose in leaf cells
Why is the organism in the diagram below considered a heterotroph rather than an autotroph?
It absorbs preformed organic molecules.
In 1883, Thomas Engelmann, a German botanist, exposed a strand of algae to different wavelengths of light. Engelmann used bacteria that concentrate near an oxygen source to determine which sections of the algae were releasing the most O2. The results are shown below. Which statement is a valid inference based on this information?
Photosynthetic rate in the algae is greatest in blue light.
Which phrase is an example of autotrophic nutrition?
an apple tree making its own food
Maple trees and tulips are classified as autotrophs because they both...
are able to synthesize organic molecules from inorganic raw materials
One immediate cause of a decrease in the rate of photosynthesis is a reduction in the availability of...
carbon dioxide
Leaves of green plants contain openings known as stomates, which are opened and closed by specialized cells allowing for gas exchange between the leaf and the outside environment. Which phrase best represents the net flow of gases involved in photosynthesis into and out of the leaf through these openings on a sunny day?
carbon dioxide moves in; oxygen moves out
The most likely result of completely removing carbon dioxide from the environment of a plant is that sugar production will....
continue at the same rate
Which process must first take place in order for the proteins in foods to be used by body cells?
digestion
Which process is used by animals to remove ingested foods that can not be digested?
egestion
Base your answer to the following question on the graph below which relates the rate of photosynthesis in a geranium plant to varying temperature and light intensity.
have little effect on the rate of photosynthesis
Base your answer to the following question on the diagram below, which represents an ameba engulfing bacteria, and on your knowledge of biology.
heterotrophic nutrition
The single opening of the hydra and the pseudopodia of the ameba are both involved in the process of
ingestion
A student has a hamburger, French fries, and soda for lunch. Which sequence represents the correct order of events in the nutritional processing of this food?
ingestion ®digestion ®absorption ® egestion
A mushroom living on a dead log uses the log for food. This is accomplished by means of
intracellular digestion followed by absorption of food
The diagram below represents the setup for an experiment. Two black paper discs are opposite each other on both sides of each of two leaves. This experimental setup would most likely be used to show that
light is necessary for photosynthesis
Chewing increases the surface area of food, helping to speed up the process of
mechanical digestion
The diagram below represents a sequence of events that occurs in living things. Letter X represents
organic molecules
The series of diagrams below represents a process carried out by a unicellular organism. This process is known as
phagocytosis
The diagram below represents a change in guard cells that open and close pores in a plant. This change directly helps to..
regulate water loss
Autotrophs differ from heterotrophs in that only autotrophs....
synthesize nutrients using carbon dioxide and water
