All about The Ocean Biome
Transcript of All about The Ocean Biome
Nutrients such as nitrates, phosphates, and silicates regulate growth, without it they wouldn't bloom and develop.
Phosphorus and fatty acids are the 2 main limiting factors, being responsible for the growth and reproduction of zooplankton. Phytoplankton:
Unlike most plants, phytoplankton don't need roots, stems, or leaves.
They absorb the nutrients and water directly from their environment
The light-absorbing pigments in their cells help them process photosynthesis.
Their skin tissues are lighter than water so they can float. Also, they are transparent, helping them camouflage. In addition, zooplankton often migrate.
They have good eye-site and swim fairly fast with their 10 arms. Some even change into luminous colors providing light and many shoot out dark ink to cloud and lose their predators.
Sharks and Killer Whales:
Killer whales are able to swim at 45 km per hour and have a layer of blubber to keep them warm. Sharks have jelly-like skin, they can grow back teeth, and can detect the signals of heart beats from hiding fish. Melissa, Ruth, & Taylor What kind of adaptations do the animals in your food chain have?
P.S. HELP US!!

Prey- Phytoplankton Limiting Factors Adaptations Interactions First thing to know about the Ocean Biome: Its FOOD CHAIN In this food chain, the producer is:
PHYTOPLANKTON So what is there to know about the food chain? Phytoplankton are at the bottom of the food chain. They use sunlight and carbon dioxide to generate energy and produce food for themselves through a process called photosynthesis. Then we have the First-Level Consumer:
ZOOPLANKTON Zooplankton is an animal type of plankton. They feed on phytoplankton to get their energy. Second-Level Consumer:
SQUID Squid mostly
eat zooplankton for their energy. With that energy, they produce ink which scares away their
predators. The squid has 2 main predators Killer Whales AND SHARKS These two predators are both the third-level consumers in this food chain. What happens when the third-level consumers die? DECOMPOSERS! After
either the killer
whale or shark dies
bacteria decompose their bodies, or break down
the waste and return raw materials to the ecosystem. Squid:
The extreme water pressures of the ocean limit the life for squids because they're body structure is not built to handle that kind of pressure.
Sharks and Killer Whales:
Natural mortality, or natural death causes such as predation, disease, and bio-toxins limit the life of killer whales and sharks. But even worse for killer whales, them being extinct. Bacteria:
The fact that the human body has developed defenses that allow us to survive harmful ones prevent bacteria from drastically reproducing. Bacteria are able to survive in places
with or without oxygen. They can
live in any kind of environment. Lisa & Jackie What kind of interactions occur with the animals in your food chain?
