Well you have to say “Ecological Niche” >.> Otherwise, people who took their last biology course many MANY years ago won’t know what the carp you’re talking about.
Ducks keep the populations of smaller fish stable, and also serve as food for several land/water based predators such as crocodiles.

They are both apex or tertiary predators (top of the food chain) so in that way they inhabit the same niche in different environments.

the relational position of a species or population in its ecosystem to each other; e.g. a dolphin could potentially be in another ecological niche from one that travels in a different pod if the members of these pods utilize significantly different food resources and foraging methods.
A shorthand definition of niche is how an organism makes a living.
The ecological niche describes how an organism or population responds to the distribution of resources and competitors (e.g., by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (e.g., limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey).
