What are some examples of marine ecosystems?
Coral reefs, kelp forests, open ocean, deep sea vents

What is the difference between a sea and an ocean?
The main difference is their size and the presence of land boundaries. Oceans are larger and are not completely surrounded by land, while seas are smaller and are partially enclosed by land.
Seas are only found in the Northern Hemisphere, while oceans are only found in the Southern Hemisphere.

Oceans are saltwater bodies, while seas are freshwater bodies.

Air pollution
Pollution, overfishing, habitat destruction, climate change, and invasive species
Deforestation
How do freshwater and marine ecosystems contribute to the environment?
They contribute by maintaining biodiversity, supporting food chains, and influencing climate patterns.
They contribute by supporting biodiversity, disrupting food chains, and stabilizing climate patterns.
They contribute by reducing biodiversity, breaking food chains, and influencing climate patterns.
They contribute by depleting biodiversity, disrupting food chains, and stabilizing climate patterns.
What are some ways to protect freshwater and marine ecosystems?
