Which is most likely a keystone species? biodiversity test please help me
1. wolves in Yellowstone National Park, which eat elk, who graze on willows, on which beavers depend to build their dams.
2. If genetic diversity is high, it leads to a greater combination of traits and characteristics, which increases the chance of survival for the species.
3. Ecosystems are unable to recover as quickly from damage due to invasive species and environmental changes.
4. Each coral is made up of thousands of animals called polyps.
5. an exoskeleton.
6. Transportation.
7. Ecological resilience is similar to a person recovering from the flu.
8. an ecosystemβs ability to endure in changing conditions.
9. Nutrient cycling.
10. Composting speeds up the decomposition of organic material.
11. Land that is converted to agriculture is no longer a suitable habitat for native species.
12. feed scraps to livestock.

1.wolves on Yellowstone National Park, which eat elk ,who graze on willows, on which beavers depend to build their dams
I know your pain, sorry I don't know the answer I actually came here to get it but lol I'll get it started. Answers please anyone
Answers for 2024!!
1. grasshopper
2. birds

4. break down rock into soil
5. the coral is susceptible to starvation
6. coral reef
7. keystone species
8. they have another structure to obtain oxygen

11. i cant give you the answer, but write something about how beavers creating and destroying structures can help and affect other animals, and how losing them would impact the environment around them.
12. search up a dichotomous key and look at examples, then write something about how the bird watcher can decide based on a feature of the bird. beak, feet, feather type, feather size, ect.
13. write something about trout developing thicker skin.
Trying to help is 100% right for the Biodiversity Unit Test.
Real Answers is a lifesaver!! Thank you so much, i have a 48% in science.
anyone for 2023 there's 20 questions now.
The grasshopper is a keystone species because if it were to disappear to animals would die out the frog and whiptail.
Anyone know the answers for 2022 ?
Is he right?
(1) Which is most likely a keystone species?
Answer: Wolves in Yellowstone National Park, which eat elk, who graze on willows, on which beavers depend to build their dams.
(2) Select the statement that best supports the claim that high diversity leads to resilience.
Answer: if genetic diversity is high, it leads to a greater combination of traits and characteristics, which increases the chance of survival for the species.
(3) A certain species of a turtle has an adaptation that allows it to store an unusually large amount of water in its body. The turtle also uses its wide feet to dig holes in the sand. The holes capture what little rain falls in the area. This turtle species likely lives in which biome?
Answer: Desert.
(4) Which organisms will most likely be observed only during the last stages or ecological succession in a forest?
Answer: bears.
(5) How are polyps and corals related?
Answer: each coral is made up of thousands of animals called polyps.

Answer: An exoskeleton.
(7) Which analogy best captures the concept of ecological resilience?
Answer: Ecological resilience is similar to a person recovering from the flu.

Answer: Lack of sufficient water.
(11) Which of the following would be most helpful for identifying the species of a bird using a dichotomous key?
Answer: Has a long, needle-sharped beak.
(12) Select the correct answer from the list.
____ is the process in which species change over time to have characteristics that help them survive in an environment.
Answer: Evolution.
OMG I'M STUCK ON THE SAME 20 QUESTION TEST TOO! π«π
I don't know to but I will try to remember to post the answers when I find them out
The keystone species one is frog
TY ab
idk
bro is anyone right?
Different tests mine is totally different for the Biodiversity Unit Test
Oops I meant to say *well* instead of will
1. Which one of the following animals is most likely to be a keystone species, based on the food web provided?
Grasshopper
2.Based on the data below, which group of animals are genetically diverse?
Birds
3.The Northern Pacific seastar is a particularly successful invasive species. Which of the following explains why it is so successful in the waters of southeastern Australia, outside of its native environment?
It breeds rapidly and has no predators in this environment.
4. Aside from killing native species, what other negative issue might an invasive species present?
They might introduce other organisms, like viruses and bacteria.
5.What happens after coral is bleached?
The coral is susceptible to starvation.
6.The most biodiverse ecosystem in the world is likely a
coral reef
7. The Florissant Fossil Beds in Colorado are home to several massive redwood stumps that were subjected to a special kind of fossilization millions of years ago. What service could these fossilized stumps most likely provide?
tourism
8.Marine biologist Dr. James Estes researched sea otters and their habitats in the Aleutian Islands of the North Pacific Ocean. Sea otters feed on animals such as crabs and urchins. Islands with sea otters contained a lot of kelp, a seaweed that is an important food source for fish and other sea animals. However, Islands without otters had large populations of urchins but no kelp since sea urchins feed on this seaweed. Since sea otters are able to control the population of urchins, this allows for kelp to freely grow in those areas. Given this information, what term best describes the otter in the Aleutian Islands ecosystem?
keystone species
9.Your friend John is having trouble with his compost bin. The material in his compost pile doesnβt seem to be decomposing well. You take a sample of the pile and check for the presence of microorganisms under the microscope. You see that there are indeed microorganisms; however, they donβt appear to be growing very fast. John says that he regularly mixes his compost pile to expose it to oxygen but has noticed the pile feels cold. What is the most likely explanation for this problem?
The compost pile contained incorrect amounts of "greens" and "browns".
10. βGreenβ material has high amounts of
nitrogen
11.Some students decide to plant their own garden. They want to eat a more plant-based diet. For meat, they will buy locally from a butcher. Any remaining plant-based scraps will be composted and used as fertilizer for their garden.
Which part of this plan represents recycling to reduce their waste?
composting craps
12. Plants, bison, elk, and wolves are all members of an ecosystem. The bison and elk are both primary consumers in this ecosystem, while the wolves are a predator. Over time, the bison completely disappear. Give an example of how the ecosystem may respond to this change, and explain how this relates to both resiliency and biodiversity.
(you have to come up with your own, or get one off brainly or something, just make sure to reword it, so therefore, you won't get caught).
13.Beavers, large members of the rodent family in North America, are often referred to as βecosystem/keystone engineersβ by wildlife managers. Ecosystem engineers are described as animals that create, alter, or destroy a habitat. Beavers contribute to river ecosystems by bringing down old and dead trees along riverbanks. They use these trees to make their dams. Although these dams are primarily used for protection and food storage, scientists report that these dams change the surrounding environment in different ways.
Given this information, in three to five sentences, describe a potential benefit that beavers contribute to the ecosystem as keystone engineers and describe a plausible impact that the removal of beavers could have on the surrounding ecosystem.
(you have to come up with your own, or get one off brainly or something, just make sure to reword it, so therefore, you won't get caught).
14.Some students are trying to convince their parents to let them raise backyard chickens. They want to present a logical argument on how raising your own chickens reduces food waste. In three to five sentences, construct an argument for how raising livestock yourself can help you reduce, reuse, and recycle waste.
(you have to come up with your own, or get one off brainly or something, just make sure to reword it, so therefore, you won't get caught).
