Answer:

Phytoplankton

Explanation:

Formed by unicellular eukaryote microalgae, phytoplankton is defined as the portion of planktonic organisms capable of photosynthesis, constituting the basis of the food chain in aquatic ecosystems. For this reason, we can say that in an ocean ecosystem, phytoplankton production is necessary to start a food chain.

Phytoplankton are composed of individuals from different taxonomic groups that have some common characteristics: they all have individualized nucleus and complex organelles in their cytoplasm, as well as photosynthetic pigments (chlorophyll a, b, carotenoids). These organisms, predominantly autotrophic, can also ingest particles, being characterized in some cases as myxotrophic.

Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels.
