The best way to represent the data of species conservation status would be a bar graph. Bar graphs are effective for comparing different categories (in this case, types of species) and their respective percentages for critically endangered and endangered or vulnerable statuses.
-
The destruction of rainforests may affect the balance of gases in Earth's atmosphere by increasing carbon dioxide and decreasing oxygen. This is because trees absorb carbon dioxide during photosynthesis and release oxygen; removing them would disrupt this process.
-
A limiting factor for a ground squirrel population is a population of hawks. Predation by hawks can reduce the number of ground squirrels, thus limiting their population growth.
-
The most accurate title for the picture showing small plants sprouting from a cooled lava rock field would be primary succession after a volcanic eruption. This process occurs when new land is created, such as after a volcanic event, allowing life to start anew.
-
Nonnative species are a threat to biodiversity because they often use up resources that other organisms need. They can outcompete native species for food and habitat, leading to declines in native populations.

-
The correct list of three greenhouse gases is carbon dioxide, nitrous oxide, methane. These gases are known for their role in trapping heat in the atmosphere and contributing to climate change.
-
The best explanation of the effect of reforestation on land is It restores trees to areas where they once grew. Reforestation is the process of planting trees in an area where there was previously forested land.
-
If the wolf population increased, it is most likely that the deer population would decrease. As a predator, an increase in wolves would likely lead to higher predation on deer, leading to a decline in their population.
-
The explanation best supported by the numbers in the chart is The dwindling zebra population has led to the decline of the predator lion and cheetah populations. As the zebra population decreases, the availability of food for lions and cheetahs also decreases, contributing to their decline.
-
The relationship between the jaguar and turtles is best described as a predator-prey relationship. Jaguars prey on turtles, which is indicative of a predator (jaguar) capturing and feeding on its prey (turtle).

14. Which graph best represents the relationship between sustainability and biodiversity?
The image shows a graph with ‘Sustainability’ on the vertical axis and ‘Increasing Biodiversity’ on the horizontal axis. The graph has a straight, upward-sloping red line, indicating a positive correlation between biodiversity and sustainability. Essentially, it suggests that as biodiversity increases, sustainability also improves. GRAPH 1
The image shows a graph with two axes. The horizontal axis is labeled “Increasing Biodiversity” and the vertical axis is labeled “Sustainability.” A red line starts at the top left corner of the graph, indicating high sustainability with low biodiversity, and declines linearly towards the bottom right corner, suggesting that as biodiversity increases, sustainability decreases. This could be interesting or relevant in discussions about environmental science, ecology, or resource management where the relationship between biodiversity and sustainability is being explored or challenged. GRAPH 2
The image shows a graph with two axes. The horizontal axis is labeled “Increasing Biodiversity” and the vertical axis is labeled “Sustainability.” There is a red vertical line drawn on the graph, but there are no units or scale indicated on either axis. There are no other labels, data points, or curves on the graph. GRAPH 3
The image shows a graph with two axes. The vertical axis is labeled “Sustainability” and the horizontal axis is labeled “Increasing Biodiversity.” There are no data points, lines, or curves on the graph itself, only the axes and their labels. It seems to be a conceptual representation, suggesting that as biodiversity increases, sustainability might also increase. However, without any plotted data or additional context, it’s not possible to infer any specific relationship from this image alone. GRAPH 4

The substance that is a greenhouse gas emitted by human activities, is the most widespread, and remains in the air the longest is carbon dioxide. It is a significant contributor to climate change due to its lengthy atmospheric lifespan.
-
The graph that best represents the relationship between sustainability and biodiversity is GRAPH 1, which shows a positive correlation between increasing biodiversity and sustainability, indicating that as biodiversity increases, sustainability improves.
-
The three renewable resources used by the restaurant are produce, sunlight, wood. These resources can be replenished over time, unlike metals like copper and aluminum, which are non-renewable on a practical timescale.
16. Which statement explains how smog forms?
Volcanoes erupt and release ash into the sky.
Strong storms pick up soil and mix it with fog.
Sunlight and heat react with gases in the atmosphere.
Gases move high into the atmosphere and then fall to Earth in rain.

density-independent factors
density-dependent factors
population-dependent factors
population-independent factors

100
128
256
320
20. How would an increase in nest sites affect a population of pigeons?
The population would decrease.
The population would increase.
The population would remain almost the same.
The population would be reduced the next year.
-
Thank you for the clarification! If the graph shows a diagonal line starting from the bottom corner and rising up, it indicates that as biodiversity increases, sustainability also improves. This would mean that GRAPH 1 described initially might still be the intended answer, reflecting that positive correlation.
-
The statement that explains how smog forms is Sunlight and heat react with gases in the atmosphere. This is a result of photochemical reactions, typically involving pollutants from vehicles, industrial activities, and other sources.
-
The human activity correctly paired with the greenhouse gas that it increases is landfilling and carbon dioxide. Landfills produce carbon dioxide as organic waste decomposes anaerobically and contributes to greenhouse gas emissions.
-
The seasonal drought in the Serengeti plains primarily affects density-independent factors. These factors impact all individuals in a population regardless of their density, such as natural disasters, climate events, and, in this case, prolonged lack of resources like water.
-
If the trout population grew exponentially from 4 to 16 to 64 in successive years, you can observe that it quadrupled each year (4 to 16 is a factor of 4, and 16 to 64 is also a factor of 4). Therefore, if it continued to grow exponentially, approximately there would be 256 trout in 1995 (64 multiplied by 4).
-
An increase in nest sites would likely lead to The population would increase. More available nesting sites can support more breeding pairs, allowing the pigeon population to grow.
What is the most likely result of this process?

-
The most likely result of favorable adaptations building up in a population over many generations due to long-term environmental change is speciation. As populations adapt to different environments or changes over time, they may evolve into distinct species.
-
The environmental change considered short term is a forest fire. Unlike ice ages or mountain building, which occur over much longer timescales, forest fires can happen quickly and have immediate effects on ecosystems.
-
Limiting factors determine carrying capacity. These factors can include resources like food, water, habitat space, and other environmental constraints that affect population growth.
-
The most likely mode of introduction for the white perch into the Great Lakes is that it was trapped in a ship's ballast or a water tank. Many invasive species are unintentionally introduced to new environments through water transport systems.
