Describe a mangrove
A coastal habitat with a high biodiversity, the trees roots are usually submerged with water and are tangled. The vegetation is dense
1 of 16
Give one reason why mangroves are important
They support varieties of marine wildlife and allow species to grow before relocating to coral reefs as they are safer
2 of 16
In a mangrove what does bacteria do?
Bacteria breaks down dead leaves and detritus (dead organic matter)
3 of 16
What is a ecosystem?
Community of living organisms
4 of 16
Whats the difference between biotic and abiotic?
biotic- living abiotic- non-living
5 of 16
Threats to mangroves
Clearance, construction, draining land
6 of 16
Why are mangroves destroyed?
For raw material, economic gain, salt harvesting as waters are saline
7 of 16
Why are coral reefs important?
They can protect coastlines from natural disasters like tsunamis, habitat to hundreds for species, increase worlds diversity, help control carbon dioxide levels in water
8 of 16
Three ways a coral reef managed sustainably?
aquaculture, marine zoning, ecotourism
9 of 16
Whats a food web?
system of interlocking food chains
10 of 16
How food webs are disturbed by human activity?
Hunting of animals, overfishing, commercial fishing
11 of 16
Siltation
When silt settles out of sea water into eco-sytems, silt erosion is driven by deforestation
12 of 16
Why are sea levels rising?
Thermal expansion as water warms up and due to warmer waters glaciers and ice melting
13 of 16
Why is rising sea levels a threat to marine eco-systems?
Corals live in shallow tropical waters meaning photosynthesis can't take place, flooding is prone meaning mangrove could have increased erosion
14 of 16
Pressures to eco-systems
Growing populations, tourism increase, waste from coastal development, high demand for fishing
15 of 16
One way overfishing could be managed
Monitoring systems to make sure fishermen don't take more fish than the are supposed too.
