This food web represents organisms in a field. What role do raccoons play in this food web? (5.9B)
Prey
Producer
Decomposer
Consumer
The diets of several types of prairie animals are described in the table. Which of the following prairie food chains is in the correct order? (5.9B)
The food web shown is made up of organisms that live in a forest. Which change would most likely occur if all the producers in this ecosystem were removed? (5.9B)
The mice would become the new producers.
All the animals would either die or move away.
The number of mice would increase.
All the animal populations would increase.
A freshwater ecosystem has various food webs. One of these food webs is shown here. Which organisms transfer the most energy within the food web? (5.9B)
Bass, because they are predators in this web
Copepods, because they support two chains in this web
Crayfish, because they are at the bottom of this web
Algae, because they are the producers in this web
A food web for some organisms in an African rain forest is shown below. Which organisms in this food web eat only consumers? (5.9B)
Okapis
Civets
Leopards
Gorillas
A partial food web of a pond ecosystem is shown. Which type of organism is missing from this food web? (5.9B)
Decomposers
Producers
Predators
Consumers
A partial wetland food web is shown. Which statement correctly describes the transfer of energy in a food chain in this wetland? (5.9B)
Energy is transferred from hawks to shrews to grasshoppers to marsh grasses.
Energy is transferred from marsh grasses to crickets to hawks to frogs.
Energy is transferred from grasshoppers to crickets to frogs to hawks.
Energy is transferred from cattails to crickets to shrews to hawks.
Fertilizers used on farms near the coast can be carried to the ocean when runoff occurs during rain showers. These fertilizers can decrease the populations of fish and shellfish. Which other populations most likely decrease as a result? (5.9C)
Organisms that eat algae
Organisms that live on farms
Organisms that eat fish and shellfish
All of these
The nesting habits of four types of birds are described in the table. If all the dead branches and dying trees in a wooded area are removed, which bird's nesting habit would be most affected? (5.9C)
Baltimore oriole
Barn swallow
Downy woodpecker
Belted kingfisher
Woody plants have many different kind of leaves. Some leaves have very smooth edges, while other leaves have jagged edges, as shown in the diagram. The characteristics of plant leaves vary with the climate in which the plant naturally grows. Some scientists discovered an area with many fossilized leaves of woody plants. The scientists used data from samples of 100 leaf fossils to compare the number with smooth-edged leaves and the number with jagged-edged leaves. The scientists concluded that the plants had grown in a hot climate. Which graph most likely represents the data from the investigation? (5.9D)
What would most likely happen to the carbon dioxide-oxygen cycle if Earth's large forests were all cut down?
There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food.
The remaining plants would stop producing carbon dioxide, and animals would use less oxygen.
The remaining plants would produce more oxygen, and animals would produce less carbon dioxide.
There would be more oxygen in the atmosphere because fewer plants would be using it to produce their own food.
Which statement best describes the relationship between humans and plants in the carbon dioxide-oxygen cycle?
Humans depend on oxygen released into the air by plants, and plants depend on carbon dioxide that humans release into the air.
Plants produce carbon dioxide as a product of photosynthesis and release it into the air to provide energy for humans.
Plants depend primarily on energy supplied by oxygen for photosynthesis, a process which releases carbon dioxide needed by humans.
Humans and plants use gases in the air and the energy of sunlight to produce their own food.
Animals and plants use substances that cycle through the environment. Which substance is needed by plants to survive and is released into the environment by animals?
Oxygen
Sugar
Salt
Carbon dioxide
Many types of plants grow in a forest ecosystem. How do plants affect the air that forest animals breathe?
Plants use oxygen from the air to make food.
Plants release pollution into the air.
Plants release energy from the sun into the air.
Plants take in carbon dioxide and release oxygen into the air.
________________ could increase the amount of oxygen in the air.
Building more houses
Burning more oil
Paving more streets
Planting more trees
What is the process where animals and people use oxygen to make carbon dioxide?
Photosynthesis
Respiration
This picture shows a type of plant called kudzu. Kudzu is a fast-growing Asian vine that was introdued into the United States. Kudzu quickly uses available resources and can completely cover the plants in an area. What effect does the rapid growth of kudzu most likely have on an ecosystem? (5.9C)
The variety of native plants decreases.
The water supply in the area increases.
Weather patterns in the area change.
The number of other plants increases.
Wild Texas hogs, similar to the one shown here, are descended from hogs brought here from other countries. These wild hogs eat many different kinds of foods, including plants, fungi, and insects. Besides being very destructive to the habitats of other animals, how do wild hogs most likely harm other animals? (5.9C)
By competing with other animals for food
By moving slower than most other animals
By causing other animals to reproduce more
By eating foods that no other animals eat
