Question

In a grazing food chain the tropic levels are as follows.

• A. Hawks $\to$ Spiders $\to$ Small birds $\to$ Rose bush $\to$ Aphids
• B. Aphids $\to$ Rose bush $\to$ Small birds $\to$ Spiders $\to$ Hawks
• C. Spiders $\to$ Aphids $\to$ Small birds $\to$ Rose bush $\to$ Hawks
• D. Rosebush $\to$ Aphids $\to$ Spiders $\to$ Small birds $\to$ Hawks

Answer 1

The correct option is D Rosebush $\to$ Aphids $\to$ Spiders $\to$ Small birds $\to$ Hawks

In a grazing food chain, the Rosebush belongs to first trophic level. It is a rose plant growing as a bush. It produces its own food from photosynthesis. Aphids belong to second trophic level. They depend on rosebush for food. Spider eats aphids and belongs to third trophic level. Small birds that eat spiders belong to fourth trophic level. Hawk belongs to the last trophic level. They are carnivorous and eat small birds.

Thus, the correct answer is option D.
