An increase in the Grizzly population
A decline in the bever population
A shift in bird populations
Question 5 is A
1)C
2)D
3)D
4)B
Answer key
Question 1: Planting of trees. Who knew being eco-friendly could be negative for biodiversity? Trees are just so shady.
Question 2: All of the Above. Just like a buffet, a healthy ecosystem needs a variety of options to keep everyone satisfied. Plants, animals, and a bunch of organisms working together like a big happy family.
Question 3: All ecosystems. Biodiversity is the spice of life, and it's needed in all types of ecosystems. It's like the secret ingredient that makes everything more interesting.
Question 4: How the organisms depended on each other. Turns out, those organisms are like one big dysfunctional family. They rely on each other more than they'd like to admit.
Question 5: An increase in the Grizzly population. Who could have guessed that taking out the wolves would lead to more grizzlies? It's like the circle of life decided to go on steroids.
To find the answer to Question 1, you need to identify the option that is not a way human activity has negatively affected biodiversity. Here are the answer choices:
1. Habitat destruction
2. Introduction of invasive species
3. Planting of trees
4. Overexploitation
To answer this question, you can eliminate the options that are known to negatively affect biodiversity. Habitat destruction, introduction of invasive species, and overexploitation are all well-known human activities that have been proven to harm biodiversity. However, planting trees is generally considered to have a positive impact on biodiversity, as it helps to restore and create habitats for various species. Therefore, the correct answer is "Planting of trees."
For Question 2, you are asked to identify what a healthy ecosystem must contain to function properly. The options are:
1. A variety of plants
2. A variety of animals
3. Many organisms working together
4. All of the above
To answer this question, you need to understand that a healthy ecosystem relies on the interactions between different components. A variety of plants provides the foundation for energy flow and nutrient cycling, a variety of animals ensures a balanced predator-prey relationship and pollination, and many organisms working together create a complex web of interactions. Therefore, the answer is "All of the above."
Question 3 asks which type of ecosystem needs biodiversity. The options are:
1. Oceans only
2. Forests only
3. Deserts only
4. All ecosystems
To answer this question, you can think about the importance of biodiversity in different ecosystems. Biodiversity is essential for the resilience and stability of ecosystems, as it ensures that there are a variety of species to fulfill various ecological roles. Therefore, all ecosystems, including oceans, forests, and deserts, need biodiversity to function properly. Hence, the correct answer is "All ecosystems."
For Question 4, you are asked to identify the crucial factor that park managers did not fully understand when Yellowstone National Park was created. The options are:
1. How the organisms depended on each other
2. How many grizzlies were in the park
3. How many willows and aspens were in the park
4. What food each animal ate
To answer this question, you need to think about the ecological relationships within the park. While all options may be important factors, the crucial factor that the park managers did not fully understand at the time was how the organisms depended on each other. This is often referred to as the concept of ecological interdependence, where different species rely on each other for survival and play specific roles within the ecosystem.
Lastly, Question 5 asks which option was NOT one of the ways the extermination of the wolf population affected the biodiversity of the park. The options are:
1. A decline in the willow population
2. An increase in the Grizzly population
3. A decline in the beaver population
4. A shift in bird populations
To answer this question, you need to identify the option that does not correspond to the impacts of wolf extermination. The extermination of the wolf population in Yellowstone National Park had several effects on biodiversity, but it did not result in an increase in the Grizzly population. On the contrary, the absence of wolves led to a decline in predators, including grizzlies, as their food sources decreased. Therefore, the correct answer is "An increase in the Grizzly population."
