The legs and beak of an egret resemble those of the heron because they
- both feed on fishes
- are both birds
-
occupy similar niche
- occupy the same trophic level
The correct answer is: C
Explanation
A trophic level is defined as the role an organism plays within a food chain. These roles can include primary producers, consumers, and detritivores. Both egrets and the heron play the same role in a food chain. However, the long legs and the beaks of egret and herons are adaptive for their ecological niche as well as their feeding behaviour. These are more comprehensive compared to other adaptive features.
