Overfishing

Answer

Increasing fossil fuel use

Answer

Deforestation

Question 11

Compare the amount of energy available to primary consumers and secondary consumers in a food web.

Accepted Answer

Primary consumers have more energy available than secondary consumers.

Answer

Secondary consumers have more energy available than primary consumers.

Answer

Both have the same amount of energy available.

Answer

Neither has energy available.

Question 12

Explain why anaerobic respiration produces less energy than aerobic respiration.

Accepted Answer

Anaerobic respiration does not fully break down glucose.

Answer

Anaerobic respiration uses more oxygen.

Answer

Anaerobic respiration occurs in plants only.

Answer

Anaerobic respiration uses sunlight.

Question 13

Which mathematical representation best shows the flow of energy in an ecosystem?

Accepted Answer

Energy pyramid

Answer

Food web diagram

Answer

Carbon cycle model

Answer

Water cycle diagram

Question 14

Describe how photosynthesis and cellular respiration are connected in the carbon cycle.

Accepted Answer

Photosynthesis absorbs carbon dioxide, and cellular respiration releases it.

Answer

Photosynthesis releases carbon dioxide, and cellular respiration absorbs it.

Answer

Both processes absorb carbon dioxide.

Answer

Both processes release carbon dioxide.

Question 15

Which of the following actions would most likely help maintain ecosystem stability?

Accepted Answer

Protecting natural habitats

Answer

Introducing invasive species

Answer

Overhunting predators

Answer

Polluting water sources

Question 16

A city wants to reduce its carbon footprint. Which strategy would be most effective?

Accepted Answer

Plant more trees in urban areas

Answer

Increase car usage

Answer

Use more coal for energy

Answer

Reduce recycling programs

Question 17

Given evidence of increased atmospheric carbon dioxide, construct an explanation for how this might affect the cycling of matter and flow of energy in ecosystems.

Accepted Answer

Increased CO $$_2$$ can enhance photosynthesis, potentially increasing energy flow, but may also disrupt ecosystem balance.

Answer

Increased CO $$_2$$ will decrease plant growth and reduce energy flow.

Answer

Increased CO $$_2$$ has no effect on ecosystems.

Answer

Increased CO $$_2$$ only affects animal respiration.

Question 18

A scientist collects data showing a decrease in the number of top predators in an ecosystem. Use reasoning to predict the possible impact on the cycling of matter and flow of energy.

Accepted Answer

There may be an increase in herbivore populations, leading to overconsumption of producers and disruption of energy flow.

Answer

The cycling of matter and energy will remain unchanged.

Answer

The number of producers will increase.

Answer

The ecosystem will become more stable.

Question 19

Develop a model to illustrate how carbon moves between the biosphere, atmosphere, hydrosphere, and geosphere during photosynthesis and cellular respiration.

Accepted Answer

Carbon cycles between all four spheres through processes like photosynthesis (atmosphere to biosphere) and respiration (biosphere to atmosphere), as well as through water and soil.

Answer

Carbon only moves from the atmosphere to the biosphere.

Answer

Carbon stays only in the geosphere.

Answer

Carbon is not cycled in ecosystems.

Question 20

Evaluate the effectiveness of creating wildlife corridors as a solution to reduce the impacts of human activities on biodiversity.

Accepted Answer

Wildlife corridors can help maintain genetic diversity and allow species to migrate, reducing negative impacts of habitat fragmentation.

Answer

Wildlife corridors have no effect on biodiversity.

Answer

Wildlife corridors increase habitat destruction.

Answer

Wildlife corridors only benefit plants.
