Answer 1

A food chain consists of different trophic levels, including the primary consumer, secondary consumer, tertiary consumer, and quaternary consumer. The Chinook salmon is an example of a quaternary consumer in the Lake Ontario food chain.

Step-by-step explanation:

A food chain consists of different trophic levels, representing the feeding positions of organisms in an ecosystem. The primary consumer is the herbivore that eats the primary producer, which is the plant or photosynthetic organism. The secondary consumer is a carnivore that eats the primary consumer, while the tertiary consumer is a carnivore that eats other carnivores. The quaternary consumer refers to an organism that consumes the tertiary consumer. In the Lake Ontario food chain example, the Chinook salmon is the apex consumer, representing the quaternary consumer that feeds on other carnivorous fish.
