Question: Assuming that all the elk in the swamp area in the video migrate elsewhere, what happens

Choices:
A. The ecosystem stabilizes as wolves and bears adapt to hunting smaller prey species in the region.
B. Wolves and bears form a temporary alliance to migrate together in search of new food sources.
C. Conflicts between wolves and bears in the area over food intensify until one side is defeated and leaves the area.
D. Population densities of wolves and bears decrease significantly due to the lack of available prey.

Answer: C

Conflicts between wolves and bears in the area over food intensify until one side is defeated and leaves the area.

Moose lives in swampy areas, locally providing it with ample vegetation [00:20:50->00:21:25]

Wolves and bears fighting over a deer carcass [00:36:23->00:39:00]

If all the elk migrated elsewhere, it would cause an even more severe food shortage for carnivores (wolves and bears), which, although supplemented by fish and birds, are not nearly as abundant or difficult to kill as elk

thereby exacerbating their conflicts and rivalries and hunting each other, leading to population declines

Until one side is completely defeated and flees the area.

Question: How many species of animal pups appear in the video

Choices:
A. Three species of animal cubs appeared
B. Seven species of animal cubs appeared
C. Four species of animal cubs appeared
D. Five species of animal cubs appeared

Question: What kind of connections exist between the various organisms in the ecology of the Everglades in the video

Choices:
A. Various organisms play the roles of producer, consumer, and decomposer roles, respectively, and work together to maintain the stability of the entire Everglades ecosystem
B. Organisms in the Everglades primarily compete for resources, leading to a dynamic but unstable ecosystem with frequent population fluctuations
C. The Everglades ecosystem is dominated by a single keystone species, which controls the population of all other organisms through predation
D. Organisms in the Everglades exist in isolated groups with minimal interaction, resulting in a fragmented and less interdependent ecosystem

Answer: A

Various organisms play the roles of producer, consumer, and decomposer roles, respectively, and work together to maintain the stability of the entire Everglades ecosystem

Plants act as producers, supplying food sources for herbivores and insects [00:21:09->00:21:19]

Carnivores prey on herbivores, they're part of the food chain, they're consumers [00:36:23->00:36:55]

Animal feces and carcasses are broken down by a variety of microbial decomposers returning energy to the swamp to provide nutrients for the plants [00:41:40->00:44:28]

Insects, fish, frogs, and birds also collectively form a link in the food chain and are also consumers [00:53:41->00:58:58]

Producers, consumers, and decomposers in the marsh ecosystem play their own roles and work together to maintain a stable and orderly ecosystem [01:23:28->01:23:44]

Question: What will be the impact of continued human activity on the ecosystem as a whole?

Choices:
A. The stability of the resistance of the entire ecosystem will continue to diminish and eventually backfire on humans, affecting their normal lives
B. The biodiversity of the ecosystem will remain unchanged, as human activities have minimal long-term effects on ecological balance
C. The ecosystem will adapt rapidly to human activities, resulting in enhanced ecological functions and services
D. The resilience of the ecosystem will increase, leading to a more balanced and sustainable environment for all species

Answer: A

The stability of the resistance of the entire ecosystem will continue to diminish and eventually backfire on humans, affecting their normal lives

Human activities are reducing the size of the marsh [00:49:44->00:51:29]

Ongoing human activities are destroying wetland ecosystems with hydrological adjustment, biodiversity conservation, climate regulation and diminishing their size

This leads to a reduction in the biodiversity of the entire ecosystem, a deterioration of hydrological and climatic regulation, and the entry into a cycle of nausea, with diminishing resistance stability of the system

This in turn leads to more environmental problems, the environment becomes more and more hostile, and ultimately backfires on humans, affecting their normal lives.

Question: How many ways do plants reproduce sexually appear in the video?

Choices:
A. A single approach was predominantly featured
B. Two distinct methods were highlighted
C. Three types emerged
D. Four primary mechanisms were demonstrated

Answer: C

The first, pollination by wind allowing seeds to blow down elsewhere [00:10:35->00:11:22]

The second one, pollination through the compression of the plant's own special structure by ejecting the seeds elsewhere [00:45:39->00:46:27]

The third, pollination by insects [01:06:36->01:07:05]

Question: Assuming there is not enough rain, what happens to the swamp in the video

Choices:
A. Decrease in the variety and number of organisms in the Everglades, but eventual stabilization
B. Increase in biodiversity due to the adaptation of drought-resistant species
C. Immediate collapse of the entire food web without any recovery
D. Rapid expansion of aquatic species leading to ecosystem imbalance

Answer: A

Decrease in the variety and number of organisms in the Everglades, but eventual stabilization

Continued heavy rains bring a lot of rain to the swamp area [00:31:54->00:34:40]

If there is not enough rain, it may lead to a lack of water for the plants in the swamp, which could result in a decrease in plant populations

The decline in plant populations also causes food problems for herbivores and various insects, leading to a decline in their numbers

At the same time, the lack of rainfall, the water level drops, squeezing the living space of aquatic plants and animals, such as fish, will also reduce their numbers, and the various birds and animals that feed on them will also be affected, reducing their numbers and even triggering large-scale migrations.

Eventually the variety and number of organisms is reduced to a state that maintains the equilibrium of the system, and the system is stabilized.

Question: What is the main point of this video

Choices:
A. By showcasing the recreational activities available in the Everglades, such as hiking and birdwatching, the video highlights its potential as a tourist destination rather than its role in conservation or historical preservation.
B. The video primarily focuses on the geological formation of the Everglades, detailing the specific processes that shaped its landscape over millions of years, without emphasizing its ecological or historical significance.
C. Through an in-depth analysis of the unique characteristics of the mysterious Everglades and the survival of its various creatures, it demonstrates its important role as a preservation site for natural wonders and historical sites, while stimulating the audience's interest in nature conservation and historical exploration.
D. The video emphasizes the economic benefits of the Everglades, discussing its contributions to local industries like fishing and tourism, while downplaying its ecological and historical importance.

Answer: C

Through an in-depth analysis of the unique characteristics of the mysterious Everglades and the survival of its various creatures, it demonstrates its important role as a preservation site for natural wonders and historical sites, while stimulating the audience's interest in nature conservation and historical exploration.

Question: Why does the video say a sandpiper ran away "in shame"?

Choices:
A. Because he had lost a territorial dispute and was embarrassed by his defeat, he ran away "in shame".
B. Because he had been startled by a predator and was too frightened to stay, he ran away "in shame".
C. Because he had been courting all night and had failed, he was a little anxious when he left, so he ran away "in shame"!
D. Because he had successfully courted a mate but was overwhelmed by the attention, he ran away "in shame".

Answer: C

Because he had been courting all night and had failed, he was a little anxious when he left, so he ran away "in shame"!

When it's breeding season, the chukar will look for objects in specific places [00:11:33->00:11:55]

They sell their attraction to the opposite sex by being in obvious positions, complex dances, and special loud noises, and it can be seen that courtship behavior is quite physically wasteful [00:12:38->00:13:20].

The chukar's courtship behavior continues throughout the night, but it doesn't end in favor with a member of the opposite sex, and the chukar quickly leaves, making it feel like it's "slinking" away, so the video teases it for running away "in shame" [00:13:30->00:14:]. 05]

Question: What would happen if the courtship of the churchwarden in the video was successful

Choices:
A. Engaging in elaborate mating displays to attract additional potential mates
B. Finding safe and suitable places to nest, nurture the next generation, and prepare for fall migration
C. Establishing territorial boundaries and defending against rival males throughout the breeding season
D. Focusing solely on foraging and energy storage for the upcoming winter months

Answer: B

Finding safe and suitable places to nest, nurture the next generation, and prepare for fall migration

They sell their attraction to the opposite sex by being in obvious positions, intricate dances, special loud noises [00:12:38->00:13:20]

If the courtship of the choughs in the video is successful, they will look for a suitable place to build their nests

Then mating, egg laying, and egg incubation until the chicks hatch

Eventually the chicks slowly learn to grow under the protection of their mothers in preparation for fall migration
