seagrass ecosystems help protect animals with shells or external skeletons. Seagrasses and phytoplankton near the ocean’s surface form the base of the aquatic food chain as they produce their ...

But the absorption of all that CO2 is changing water chemistry, creating acidic seawater and altering marine ecosystems at their core through base-of-the-food-chain animals such as plankton and ...

Following January's wildfires, there have been reports of increased debris floating off the Southern California coast, including a viral video that showed a floating debris island off the coast of ...

All organisms in an ecosystem depend on each other. Food chains show the flow of energy from one organism to another. Food chains show the feeding relationships between organisms. Food webs show ...

Tuna are essential for a healthy ocean ecosystem. Being an apex predator at the top of the food chain, tuna are a significant part of the ocean nutrient pump transporting nutrients to the sea surface ...

A study by McGill University on a Cretaceous marine ecosystem reveals that the predators at the top of the food chain 130 million years ago exerted a dominance unmatched by modern species. The study, ...

A new method of tracking the dietary habits and contaminant exposure of animals in Arctic marine ecosystems is providing critical insights as climate change reshapes the region's food web.
