Correct Option (A):
Certain species of ants, notably leafcutter ants, are well-known for their sophisticated fungus-farming behavior. These ants collect plant material, such as leaves, which they do not consume directly. Instead, they transport this material to their underground nests to serve as a substrate for cultivating specific species of fungi. The ants then feed exclusively on these cultivated fungi. In return, the ants actively manage and protect their fungal gardens from pests, pathogens, and competing fungi, demonstrating a highly evolved mutualistic symbiotic relationship essential for the survival of both organisms.
Incorrect Options:
- Cockroaches are omnivorous insects known for scavenging, but they do not cultivate fungi. Their diet primarily consists of decaying organic matter, starches, and sugars.
- Crabs are aquatic crustaceans that are primarily scavengers or herbivores. They do not exhibit fungus cultivation behavior.
- Spiders are predatory arachnids that capture and consume other insects or small animals. They do not engage in fungus farming or any form of agriculture.
