In a specific interspecific interaction, Species A is assigned a (+) sign and Species B is assigned a (-) sign. Which of the following evolutionary adaptations is most likely to be found in Species B to minimize the impact of this interaction?
Options
- ACryptic coloration to avoid detection
- BLoss of unnecessary sense organs
- CPresence of adhesive organs or suckers
- DComplete loss of the digestive system
Correct answer
A. Cryptic coloration to avoid detection
Step-by-step solution
An interaction represented by (+, -) indicates either predation or parasitism. In this scenario, Species A receives the benefit (+) and is therefore the predator or parasite. Species B is harmed (-) and represents the prey or host. To minimize the impact of this interaction, Species B (the prey/host) would evolve defense mechanisms. Cryptic coloration (camouflage) is a classic evolutionary adaptation in prey species (like certain insects and frogs) to avoid being detected easily by predators. The other options (los
