Final answer:
The term 'Mimicry' describes a morphological adaptation in which one species evolves to resemble another, offering survival benefits such as predator avoidance. It differs from camouflage, which is blending in with the environment, and analogous structures that arise from similar selection pressures but not shared ancestry.
Step-by-step explanation:
The correct answer to the question “A morphological adaptation in which one species resembles another is called __” is: A) Mimicry.Mimicry is a fascinating evolutionary adaptation where one species evolves to resemble another. This can convey various advantages such as predator avoidance, increased efficiency in finding prey, or improved reproductive success. Camouflage, on the other hand, is an adaptation that allows an organism to blend into its environment to avoid detection. While both mimicry and camouflage are forms of adaptation that can increase an organism's chances of survival, they are distinct concepts.
Mimicry often involves actively imitating the appearance, behavior, or sound of another species, whereas camouflage is about blending in with the surroundings. An example of mimicry is a harmless species evolving to resemble a harmful one to deter predators, as seen in certain species of non-poisonous insects adopting the warning colors of poisonous ones. Analogous structures are features in different species that have a similar function but did not arise from a common ancestral trait. It's noteworthy that mimicry and camouflage can sometimes be viewed as aposematic defense mechanisms when they are used to warn predators of an organism's unpalatability or toxicity.
