Questions and answers of the young-yeng environmental protection competition
I. Selected topics (10 in total)
1. Answer d
[disarmament] seastars can feed on organic matter in the oceans and contribute to the purification of the marine environment and are therefore called `cleaners in the oceans'。
2. "answer" c
[disarmament] participation in marine clean-up activities contributes to the protection of the marine environment and other options can cause pollution or damage to the marine environment。
3. D
The phenomenon of [decomposition] red tides is often caused by pollution from seawater, especially by pollutants rich in nutrients entering the sea, leading to the overproduction of some algae。
4. Answer c
[dissect] seagrass is a producer of marine ecosystems capable of photocooperative use that provides food and oxygen to marine life。
5. [answer]c
The establishment of marine protected areas could effectively protect marine biodiversity and limit the damage to marine ecosystems caused by human activities。
6. [answer]c
[dissect] the tide of water is a renewable resource that can be converted into electricity through tidal movements。
7. A
[disarmament] coral reefs provide rich habitats for marine life and are an important part of marine ecosystems。
8. Answer d
[assemination] of submarine volcanic eruptions is a natural phenomenon, while other options are pollution or destruction caused by human activity。
9. [answer]c
[disarmament] participation in marine clean-up activities contributes to the protection of marine biodiversity and other acts can cause harm to marine life。
Ii. Multi-selection topics (5 in total)
10. Abcd
[disarm] industrial wastewater discharges, household sewage discharges, pesticide fertilizer loss and fishery debris are the main causes of marine pollution。
11. Abcd
The establishment of marine protected natural areas, the limitation of overfishing, the promotion of the sustainable use of marine living resources and the enhancement of education on the protection of the marine environment are all effective measures to protect marine biodiversity。
12. Abd
The green turtles, whales and chinese walrus are all internationally endangered species, although they are also endangered species but mainly live on land and are not marine organisms。
13. Abcd
[disassessing] ocean circulation, migration of marine life, ocean tides and ocean sedimentation all have a positive impact on marine ecosystems and preserves their ecological balance。
14. Abcd
Reducing the use of disposable plastics, increasing the recycling of plastics, banning littering on beaches and raising public awareness of marine environmental issues can all contribute to reducing marine plastic pollution。

15. Plankton
[dissect] the phytoplankton produces oxygen through photocosy and is the main source of oxygen in the oceans。
16. June 8th
World oceans day [discussed] is 8 june of each year and aims to increase global public awareness and protection of the oceans and their resources。

The kreutchev basin marine protected area is located in russia and is the largest marine protected area in the world, covering an area of approximately 150 million square kilometres。
19. Overfishing
[discussed] overfishing refers to fishing faster than the reproduction of living stocks, leading to a decrease in the number of living stocks and affecting the ecological balance of the oceans。
Iv. Questions of judgement (5 in total)
20. Error
[disarm] marine pollution not only harms marine life but also affects human health and economic development。
21. Wrong
The coral reefs have a variety of colors, not only red, but also white, brown, yellow。
22. Errors
[disarmament] plankton plays an important role in marine ecosystems and is the foundation of the marine food chain, not all of which are harmful。
23. Errors
[disarm] the effects of the oil spill on the marine environment are long-term, natural decomposition takes a long time and leaves hazardous substances behind。
24. Error
[disarmament] while marine protected areas can limit human activities, they do not entirely prevent damage to the oceans and require continuous management and oversight。
V. Brief answers (5 in total)
25. [the answer] the food chain in marine ecosystems consists of producers, consumers and decomposers. Producers are usually phytoplankton, which manufacture organic matter through photocooperative use. Consumers include zooplankton, fish, marine mammals, etc., who prey on producers or other consumers. Decomposers such as coral reefs, bacteria, etc. Decompose organic debris, transform organic matter into inorganic matter and re-enter the food chain。
[dissect] the food chain is the process of describing the transfer of energy between organisms, each of which is an integral part of the ecosystem。
26. [the answer] marine pollution destroys marine ecosystems and affects the living environment of marine life. Contaminants such as oil, plastics and heavy metals can accumulate in organisms, leading to biotoxication and even death. In addition, pollution destroys the habitat of marine life, alters the marine environment and renders some species unviable。
The threat to marine biodiversity from marine pollution is [discovered] multifaceted and encompasses both direct and indirect impacts。
27. [the answer] effective ways to protect marine biodiversity include establishing marine protected areas, limiting overfishing, promoting sustainable use of marine resources, reducing marine pollution, and enhancing marine environmental awareness education。
[disarmament] comprehensive conservation measures are key to ensuring the sustainability of marine biodiversity and require a concerted effort by all countries globally。
28. [the answer] coral reefs are `tropical rainforests' in marine ecosystems that provide rich biodiversity and habitat for countless marine organisms. Coral reefs also absorb large amounts of carbon dioxide and contribute to mitigating global climate change。
[disarmament] coral reefs play an important role in maintaining marine ecological balance and the earth's climate system。
29. [answer] marine resources are a precious asset of humanity, including food, energy, medicines, etc. Sustainable use of marine resources ensures the long-term availability of those resources while reducing environmental damage and achieving win-win economic development and environmental protection。
[disarmament] the sustainable use of marine resources is important for meeting human needs, promoting socio-economic development and protecting the marine environment。
