Transcript of Open Ocean Habitat

OPEN OCEAN HABITAT An open ocean habitat(also known as the pelagic zone) consists of many different kinds of organisms, despite the lack of nutrients. such as...... cetaceans (whales), and blue fin tuna fish. and deeper into the pelagic zone you will find some invertebrates like jellyfish, or giant squid. ADAPTING! Most animals in the pelagic zone are torpedo shaped for speed to run from their predators. While some slow animals, adapt by being transparent like jellyfish. And other animals with lungs, like whales, adapt by being able to hold their breath for extended periods of time. ORGANISMS IN THE OPEN OCEAN! PHYSICAL ENVIRONMENT The pelagic zone is huge and well lit. It is the largest water habitat on Earth (1,370 million cubic kilometers). The pelagic zone is an enormous column of water that extends from the surface of the water to the bottom, away from shore. So because of all the zones of the open ocean(Sunlit Zone, Twilight Zone, Midnight Zone, Hadropelagic Zone) it is hard to tell the temperature and nutrients of all the layers. We suggest using the chart we made in the stations last week. INTERESTING RELATIONSHIPS
At the bottom of the food chain are algae and surface seaweeds that plankton and small fish eat. The larger fish like sharks, tuna,dolphins and whales are at the top of the food chain. They eat smaller fish and plankton. Creating the pelagic zone food chain. HUMAN EFFECTS Toxic wastes are being dumped into the open ocean every day. And its hurting plants and animals in the ocean. Also, just basic trash and gas from your cars are running off the land and into the ocean, hurting a lot of the ocean in more ways then one. HOW TO PREVENT THIS!! 1. Throw your trash in respectable places, not the side of the road (or recycle:) )
2. Use environmentally-friendly cleaners to wash your car/ fertilizer.
3. Try NOT to fill up your car gas tank as often as possible(dont do it often)
4. Try not to use colored soap bars. they were found the carry more pollution to the ocean then no colored ones.
5. Avoid buying water bottles as much as possible. RESOURCES WWW. BING.COM
