What level consumer is an orca?
Autotrophs are called producers, because they produce their own food. Herbivores, carnivores, and omnivores are consumers. Killer whales, or orcas, are a classic example of tertiary consumers.
How big of a tank do orcas need?
In the wild, orcas are capable of swimming up to 100 miles a day and diving to depths of 850ft. With no current orca tank measuring longer than 220ft, or deeper than 50ft, the restrictions forcefully imposed upon orcas are drastic.
What are the four types of orca?
There are three main types of killer whales in the North Pacific: Resident, Transient, and Offshore. Each ecotype differs in appearance, diet, habitat, genetics, and behavior. While all three types share at least part of their habitats, they are not known to interbreed with each other.
What is the smallest type of orca?
The smallest ecotype is the Ross Sea orca – males reach about 20 feet (6m) long. Like other Antarctic orcas, they are grey and white and have a diatom coating that gives them a yellowish hue.
What is orcas prey?
Killer whales (also called orcas) are apex predators, meaning they are at the top of their food chain. They feed on fish and squid like other odontocetes (toothed whales) do, but will also target seals, sea birds and even whale species far bigger than themselves.
Is an orca secondary consumers?
In the example above, phytoplankton are the primary producers, zooplankton are primary consumers, small fish are secondary consumers, porpoises are tertiary consumers and orca whales are quaternary consumers.
How big are the SeaWorld orca tanks?
They are multi-million-gallon environments of continually chilled and filtered saltwater. In fact, SeaWorld Orlando’s habitat is 36 feet deep and holds more than 6 million gallons!
How deep is the Shamu pool at SeaWorld?
The new tank will be almost twice the size of its current orca tank, with 10 million gallons of water and a new depth of 50 feet (15m), and will include larger viewing points for visitors. But Peta (People for the Ethical Treatment of Animals) criticised the plans, calling them a “desperate move”.
What type of orca is Tilikum?

What is a group of orcas called?
pods
Orcas hunt in deadly pods, family groups of up to 40 individuals. There appear to be both resident and transient pod populations of orcas. These different groups may prey on different animals and use different techniques to catch them. Resident pods tend to prefer fish, while transient pods target marine mammals.
Are orcas aggressive?
Sailors along Spain and Portugal’s Atlantic coastlines have seen a recent series of puzzling incidents involving apparently aggressive orcas. While orcas are not known to attack humans, they can cause damage to boats. The boat radioed authorities to report it was “under attack” by killer whales.
How does the orca bed level system work?
The ORCA Sonar Bed Level transducer emits a high powered acoustic pulse, which is reflected from the interface density selected. The reflected signal is processed using specially developed software algorithms, that eliminate lighter floating densities and stratified layers, allowing measurement of RAS or BED levels.
What is the purpose of the ORCA system?
ORCA creates the perfect thermophilic biological environment for the microorganisms to digest food waste into a liquid. ORCA is a hyperlocal, distributed alternative to the traditional truck and bin collection system.
How does the ORCA system reduce the risk of Legionella?
The Orca system kills Legionella and Pseudomonas regardless of water temperature, so these can be reduced. The Health & Safety Executive state that once a system has been installed the temperature can be gradually brought down in commercial premises. This removes the need for expensive mixing valves that can act as a source of contamination.
Where are the silver ions in the ORCA system?
This sends a signal to the Orca control unit, which then passes a low DC current between two copper and two silver electrodes located in an electrode chamber (the ‘Pod’). The current causes the release of electrically charged copper and silver ions from the electrodes.
