Question 1

By definition, parasites ______________ their host

Accepted Answer

Parasites feed on and harm their host, often causing damage or disease in the process.

Question 2

Use the figure above to answer the following question
-If global climate change results in an area of temperate grassland receiving less rainfall and higher temperatures, it will _______________

Accepted Answer

Desert species are adapted to environments with lower rainfall and higher temperatures. If a temperate grassland experiences these changes, it would become more hospitable to species typically found in desert biomes, leading to an increase in desert species in the area.

Question 3

Use the figure above to answer the following question
-Temperate deciduous forests are characterized by _______________.

Accepted Answer

The figure shows that temperate deciduous forests are found in regions with moderate temperatures (between 10°C and 20°C) and moderate amounts of precipitation (between 500mm and 2000mm). Therefore, the best choice is C, moderate temperatures and moderate amounts of precipitation.

Question 4

Zooplankton-eating fish are ______________

Accepted Answer

Zooplankton-eating fish are considered secondary consumers because they feed on primary consumers (zooplankton), which in turn feed on primary producers (phytoplankton).

Question 5

Choose the item that best matches from the following:
-Describes the region west of the Mississippi River; characterized by limited precipitation, thick organic soils and extreme temperature variation in winter and summer

Accepted Answer

Temperate grasslands, found west of the Mississippi River in the United States, are known for their limited precipitation, thick organic soils, and significant temperature variations between winter and summer, matching the description provided.

Question 6

Use the figure above to answer the following question
-What does the diagram illustrate?

Accepted Answer

The figure illustrates the relationship between biomes (such as tundra, boreal forest, tropical rainforest, etc.) and temperature and precipitation. It shows how different biomes are associated with different ranges of temperature and precipitation, highlighting that biomes are primarily determined by these two factors.

Question 7

Choose the item that best matches from the following:
-Describes Cairo, Egypt, and northwest Mexico; characterized by sparse rainfall and much variation in temperature

Accepted Answer

Cairo, Egypt, and northwest Mexico are both located in desert regions, which are characterized by sparse rainfall and much variation in temperature.

Question 8

Choose the item that best matches from the following:
-Describes biome in the eastern United States, north central Europe, and eastern China; characterized by stable precipitation and seasonal temperature variation

Accepted Answer

The description matches the temperate deciduous forest biome found in the eastern United States, north central Europe, and eastern China. These forests have stable precipitation and seasonal temperature variation.

Question 9

Zooplankton populations in Lake Erie and the Hudson River have declined by up to 70% since the arrival of zebra mussels because ______________.

Accepted Answer

Zebra mussels feed on phytoplankton, which reduces the food available for zooplankton. This results in a decline in zooplankton populations.

Question 10

Choose the item that best matches from the following:
-Describes the terrestrial biome bordering the Mediterranean Sea; characterized by wet winters and warm dry summers

Accepted Answer

The description matches the Mediterranean biome, which is also known as the chaparral biome. It is characterized by hot dry summers and mild, wet winters, and features shrubby vegetation adapted to drought and fire.

Question 11

Use the figure above to answer the following question
-Chaparral has a climate most similar to _________________

Accepted Answer

Chaparral climates are characterized by hot, dry summers and mild, wet winters, which is most similar to the climate of savannas. Both environments experience a distinct dry season and a more humid season, differing significantly from the climates of tundra, boreal forests, tropical dry forests, and temperate rainforests.

Question 12

Use the figure above to answer the following question
-According to this diagram, you should find _____________________.

Accepted Answer

Deserts are characterized by hot and dry conditions, which can occur in various parts of the world, not limited by latitude or specific regional characteristics. This is why deserts can be found globally wherever the climatic conditions support their formation, unlike the other options which are geographically or climatically inaccurate.

Question 13

Grazing animals such as deer are ______________

Accepted Answer

Grazing animals such as deer eat vegetation, making them primary consumers or herbivores.

Question 14

Choose the item that best matches from the following:
-Describes the Pacific Northwest of the United States and Nagasaki, Japan; characterized by heavy rainfall and relatively stable temperatures

Accepted Answer

The Pacific Northwest of the United States and Nagasaki, Japan are known for their heavy rainfall and relatively stable temperatures, which are characteristic of temperate rainforests.

Question 15

Of the following, ______________ is (are) an abiotic factor.

Accepted Answer

Abiotic factors are non-living components of an ecosystem, such as climate, sunlight, water, and temperature. The other choices (A, C, D, E) are all biotic factors, which are living components of an ecosystem.

Question 16

______________ capture solar energy and use photosynthesis to produce sugars.

Accepted Answer

Producers capture solar energy and use photosynthesis to produce sugars.

Question 17

Zebra mussels ______________.

Accepted Answer

Zebra mussels are an invasive exotic species that clog water intake pipes at factories, power plants, and wastewater treatment facilities. They were introduced to North America in the 1980s and have since spread to many waterways beyond the Great Lakes and Hudson River. While they do excrete waste that can contribute to eutrophication, this is not their most significant impact.

Question 18

Which of the following is true about top predators?

Accepted Answer

Top predators are often keystone species, meaning that they have a disproportionately large effect on the ecosystem compared to their abundance. Their removal can have cascading effects on the entire food web and decrease biodiversity.

Question 19

Individuals of a single species fighting over access to a limiting resource is one example of ______________.

Accepted Answer

The scenario described in the question is an example of intraspecific competition because individuals of the same species are competing with each other for a limited resource. Symbiosis refers to a close and long-term interaction between different species, while resource partitioning and competitive exclusion involve interactions between different species. Interspecific competition refers to competition between different species for resources, while intraspecific competition refers to competition within a single species.

Question 20

Choose the item that best matches from the following:
-Describes an equatorial zone with moderate precipitation that fluctuates seasonally; characterized by warm temperatures year round

Accepted Answer

The answer of Choose the item that best matches from...
