Most of these aquatic species are tied together through the food web. Level One: Photo autotrophs The foundation of the sea's food chain is largely invisible. Countless billions of one-celled organisms, called phytoplankton, saturate sunlit upper-ocean waters worldwide.
Looking across the different food chains, which of the organisms can make their own food through photosynthesis? Compare the food chains to terrestrial food chains you may know. How are the marine food chains the same?
Most marine species are part of a food chain. A food chain is a top-to-bottom set of animals and plants. They are connected to each other because those on top eat those below. These food chains come together to form a food web. Level One: Photo autotrophs The bottom level of the ocean's food chain is made up of tiny living
Most marine species are tied together through the food web. A food web is a system of interconnected food chains. A food chain is a top-to-bottom set of animals and plants. They are linked to each other because those on top eat those below. Level One: Photo autotrophs The bottom level of the ocean's food chain is largely invisible.
Level One: Photo autotrophs The foundation of the sea's food chain is largely invisible. Countless billions of one-celled organisms, called phytoplankton , fill sunlit upper-ocean waters worldwide. They are microscopic, meaning they are too small to be seen by human eyes.
The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales (Balaenoptera musculus)—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight. A rabbit eats the grass.

Food chains are relatively easy concepts for students to understand. They show linear, one-way relationships between organisms within a given ecosystem. Students learn to tell stories of food chains as connections between living things that need food.
Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem . All of the interconnected and overlapping food chains in an ecosystem make up a food web .
