Scientists are gaining new insights into how plankton supports life on Earth — just as climate change is changing everything.

And we can see food chains happening underwater too. Algae is eaten by small fish, small fish are eaten by bigger fish, and bigger fish are eaten by sea lions who are then eaten by sharks!

If they die, there’ll be fewer big fish—and that could rattle the food chain. marine-plastic-ocean-fish-microplasticThe naturally oily surface slicks in which many ocean fish come of age are ...

Once the plastic is in the ocean, it decomposes very slowly, breaking into tiny pieces known as microplastics, which can enter the marine food chain and become incredibly damaging to sea life. The ...

Plastic doesn't biodegrade and so it enters the food chain. The artist wanted to show ... made out of plastic rubbish collected from the ocean. The plastic is connected to underwater sensors ...

Through one of the primary carbon storage mechanisms, the biological carbon pump, phytoplankton (microscopic marine plants at the bottom of the oceanic food chain) take up CO 2 in the surface ocean ...

Sustainable fisheries target plentiful species, including those smaller and lower on the food chain, because they can reproduce quickly to sustain their populations. They also mandate ...
