Phytoplankton, also known as single-celled plants, grow in water-bodies and are similar to terrestrial plants in many ways. Since they require sunlight for photosynthesis, these plants usually grow on the surface of water, in the photic zone, where sunlight can penetrate. These plants also require other nutrients such as nitrate, magnesium, zinc, etc to grow.
Diet: Animals in this zone feed on plant matter and algae that fall into this zone from the euphotic zone (the well-lit zone above the disphotic zone), animals that stray into this twilight zone, and each other. Animals in the disphotic zone are filter feeders, grazers, and predators.n average, this zone extends from 660 to 3,300 feet (200 to 1,000 m). In the disphotic zone, there is enough light to see during the day, but not enough light for photosynthesis to take place, so no plants live in this zone. The amout of light decreases with depth.
