I've got a few science questions i would like to check.
1.) An ecosystem that endures over time
Select one:
a. has reached the end of its succession process.
b. is a sustainable ecosystem. ***
c. has not experienced cycles of destruction.
d. is one that never changes.
2.) The whooping crane is endangered in your area.
What is the first step scientists must have done before listing the whooping crane as an endangered species?
Select one:
a. Estimate the whooping crane’s population ***
b. Develop a recovery plan**
c. Collect crane eggs and incubate them
d. Eliminate the crane’s predators
I think a. over b.
3.) Which of the following is an example of an ecosystem?
Select one:
a. A collection of biodegradable picnic supplies
b. A space suit
c. A shovelful of soil from a forest floor ***
d. A herd of cattle
Are these all correct?
Yes, they are all correct : )
Thank you, Ms Pi.
Yes, your answers are correct:
1.) The correct answer is b. A sustainable ecosystem. An ecosystem that endures over time is one that is able to maintain stable populations and interactions between organisms, resources, and the physical environment.
2.) The correct answer is a. Estimate the whooping crane's population. Before listing a species as endangered, scientists typically conduct population surveys and assessments to determine the population size and its status. This information is crucial in order to accurately classify and protect the species.
3.) The correct answer is c. A shovelful of soil from a forest floor. An ecosystem refers to a community of living organisms and their interactions with the abiotic factors (non-living environmental components). A shovelful of soil from a forest floor can contain a variety of organisms and represents an example of an ecosystem.
1.) Your answer for the first question is correct. An ecosystem that endures over time is a sustainable ecosystem. This means that it is able to maintain its structure and function, as well as support the organisms that are part of it, without being significantly impacted by external factors.
2.) Your answer for the second question is correct as well. Before listing a species as endangered, scientists must first estimate the population size of the species. This helps determine the level of threat the species is facing and informs conservation efforts. Developing a recovery plan would be the next step after the species is officially recognized as endangered.
3.) Your answer for the third question is also correct. An ecosystem is a community of living organisms interacting with the non-living components of their environment. A shovelful of soil from a forest floor can contain a complex web of interactions between various organisms such as plants, animals, fungi, and microorganisms, making it an example of an ecosystem. The other options mentioned do not represent complete ecosystems.
