Mangrove trees grow along coastal areas. What is the main role of mangrove trees in their ecosystem?
Providing food for herbivores
pollinating flowers
Stabilizing the shoreline
Producing oxygen
Coral reefs serve as habitat for marine animals. Which non-living factor is crucial for coral reefs to thrive?
High salinity
Low temperature
Clear water
High nutrient levels
To survive, some animals need to help each other. What type of relationship exists between clownfish and sea anemones in coral reefs?
Predation
Competition
Mutualism
Parasitism
Bacteria and fungi are known as decomposers. In what ways do decomposers contribute to the health and sustainability of tropical rainforests, coral reefs, and mangrove swamps?
They are primary producers.
They only affect the water quality.
They have no role in these ecosystems.
They break down dead organic matter, recycling nutrients
How do abiotic factors like sunlight, temperature, and water availability influence the biodiversity in tropical rainforests, coral reefs, and mangrove swamps?
They only affect plant life.
They have no significant impact.
They are irrelevant to these ecosystems.
They determine the types of species that can survive.
Tropical Rainforests provide shelter to most animals. Which of the following is a primary reason for protecting tropical rainforests?
They have low biodiversity
They provide habitat for diverse species
They are a source of minerals
They are easy to clear for agriculture
Aside from providing shelter for diverse species, tropical rainforests are often referred to as the “lungs of the Earth”. Why do you think so?
They have a high biodiversity
They cover a large area of the planet
They produce a large amount of oxygen
They absorb a significant amount of carbon dioxide
The Philippines has the third-largest coral area in the world. What role do coral reefs play in marine ecosystems?
They provide shelter for marine life
They are the main source of fresh water
They are primarily used for oil extraction
They produce large amounts of carbon dioxide
Conversion of mangroves to fishponds has been the major cause of the decrease and degradation of Philippine mangroves. Why are mangrove swamps important for coastal protection?
They increase soil erosion
They reduce marine biodiversity.
They provide no significant benefits.
They act as natural barriers against storms.
How do the physical structures of coral reefs and mangrove roots provide habitats for various marine and terrestrial species?
They are harmful to marine life.
They do not provide any habitats.
They only provide habitats for fish.
They create complex structures that offer shelter and breeding grounds.
The primary drivers of coral reef destruction include dredging, land reclamation, and artificial island construction. How does the destruction of coral reefs affect marine biodiversity?
It has no significant impact
It only affects coral species
It leads to an increase in marine species
It causes a decrease in marine biodiversity
Mangrove swamps are vital for biodiversity, coastal protection, and climate regulation. Why is it important to maintain the health of mangrove swamps?
They are a source of fresh water
They are not important for the ecosystem
They increase the risk of coastal flooding
They provide critical breeding grounds for fish
Your uncle is a contractor. He develops mangrove swamps into commercial space. How can you convince your uncle that the nearby mangrove swamp has economic value and shouldn't be converted into a commercial area?
Mangrove swamps are beautiful ecosystems.
Mangrove swamps filter pollutants from water.
Mangrove swamps provide shelter for animals.
Mangrove swamps protect the coastal community from waves and provide food and business for people.
Our country is gifted with diverse natural resources and ecosystems. Why is it essential to protect coral reefs, mangroves, and tropical rainforests? They________________
support biodiversity
help regulate climate
provide ecosystem services
all of these
Which of the following statements best explains the need to protect the rainforest, mangrove swamps, and coral reefs?
They provide resources for human consumption.
They support biodiversity and regulate climate.
They are aesthetically pleasing to see.
They are economically valuable.
Imagine the scenario when mangrove forests, rainforests, and coral reefs no longer exist. Which of the following situations would be most likely to happen?
Biodiversity would increase.
The climate would remain unchanged.
The ecosystem would remain balanced.
Coastal communities would be more prone to violent storms and soil erosion
As a member of the young generation, what is the most common benefit of protecting mangroves, rainforests, and coral reefs?
Improved human health
Reduced government regulations
Increased economic development
Enhanced ecosystem services and biodiversity
