Answer:
Predator-prey relation.
Explanation:
A predator is defined as an organism that hunts another individual, whereas a prey refers to the organism that is eaten by the predator. They tend to co-evolve (evolve together). <u>The prey is essential for the predator to survive, while the predator controls the prey populations by hunting some of the individuals.</u>
Predator-prey relations are interactions that occur between two species where one species (prey) represents a food source for the other species (predator).
The turtle (prey) is essential for the survival of the jaguar (<em>Panthera onca)</em>, while the jaguar controls the populations of turtles by preying upon them. Therefore, this is a predator-prey relation.
