The Killer whale is the top predator of the oceans, having no threats other then people when it reaches adulthood, however baby, old, and ill whales often fall prey to other predators such as sharks
It is the 2nd consumer on the trophic level! :)
The 4th trophic level is called the quaternary consumer. Organisms at this level feed on tertiary consumers, which in turn feed on secondary consumers, which feed on primary consumers.
first and second trophic levels
The 3rd trophic level contains organisms that are primary consumers, often herbivores that feed on producers from the 1st trophic level. These organisms are then consumed by predators at higher trophic levels.
Not sure what yo mean by trophic level. But the classification is called herbivore.
all organisms feed on different levels. these are called trophic levels. eg: the grass outside can be fed on by cows and horses or basically herbivores. therefore, herbivores are said to feed on one trophic level. likewise, carnivores all feed on another trophic level but omnivores can feed on two because the consume both meat and plants its food source
The killer whale is a mammal, like all whales - mammals give birth to live young which they feed with milk.
3rd or 4th
False.
The killer whale is a secondary or tertiary consumer, depending on what they eat. If the prey item feeds on plant matter, then it is a secondary consumer. However, most orcas eat prey that feed on invertebrates, shellfish or fish, making them primarily tertiary consumers.
The lowest level of the energy pyramid that contains carnivores is the third trophic level. These carnivores consume herbivores from the second trophic level that feed on producers at the first trophic level.
No, some species can feed at more than one trophic levels. For instance, humans can eat plants(first level), chickens(second level), and dogs(third level).
