Ocean Basics
What is the largest ocean on Earth?
Pacific Ocean
What type of animal is sea urchin?
Echinoderm
What is overfishing?
Catching fish faster than they reproduce
What ecosystem includes seagrass?
Shallow coastal ecosystems
Name one way to reduce plastic pollution
Recycling / reducing use
What do we call a sequence showing who eats whom?
Food chain
What do herbivores eat?
Plants
What is one effect of plastic pollution on animals?
Injury, entanglement, or death
Name one role of seagrass
Habitat / oxygen / carbon storage
What is a marine protected area?
Area where marine life is protected
What gas is causing ocean acidification?
Carbon dioxide (CO2)
Which animal undergoes a process of shedding shells (Moulting)?
Spider crabs
What causes coral bleaching?
Rising ocean temperatures
What ecosystem do sea urchins damage?
Kelp forests
What is one way of making fishing sustainable?
Catch limits / quotas
What process is increasing ocean temperature?
Climate change / global warming
What happens when sea urchin populations grow too large?
They destroy kelp forests
What is bycatch?
Catching non-target species
Why are ecosystems important?
Support biodiversity / food chains
How can individuals help protect oceans?
Reduce plastic / clean-ups / awareness
What is ocean acidification doing to marine shells?
Weakening / dissolving them
Why do spider crabs migrate in large groups?
Protection during moulting
What are two impacts of climate change on oceans?
Warming + acidification / habitat loss
What happens when one part of an ecosystem is removed?
The whole system is affected (imbalance)
Why are solutions important for marine ecosystems?
To protect biodiversity and future resources
