Refer to the following food chain: a fly eats a piece of fruit; a spider eats the fly; a bird eats the spider. the bird dies, and is decomposed. which organism is the tertiary consumer? the fly the bird the spider the fruit

The correct answer is B. The bird

Explanation:

In biology, a food chain refers to a type of network that describes the way organisms feed on others and are also eaten by other organisms, which creates different levels. In this, the first level is the producers that include plants or organism that can produce their food; primary consumers the that are herbivores and eat producers; then there are the secondary consumers that eat the herbivores; the tertiary consumers that eat the secondary consumers; the top predators and finally the decomposers. This implies in the case of the food chain presented, the fruit is the producer, the fly is the primary consumer, the spider is the secondary consumer and the bird is the tertiary consumer as this feeds on the secondary consumer.
