Correct option is A
A guild is a group of species that exploit the same resources in a similar manner, regardless of their taxonomic classification. These species may not be closely related but share functional roles in an ecosystem, competing for similar resources such as food, habitat, or nesting sites.
Characteristics of a Guild:
- Defined by resource use, not by taxonomy.
- Can include species from different families or orders.
- Members of a guild compete for similar resources.
Information Booster
- Ecological Guild Concept – Introduced in ecology to classify species by function rather than evolutionary lineage.
- Difference from Community – A guild is a subset of a community, focused on species using similar resources.
- Guilds Reduce Competition – Species in a guild partition resources to coexist (e.g., different foraging times or locations).
- Role in Ecosystem Functioning – Guilds help ecologists understand niche overlap and interspecies interactions.
- Conservation Implications – Protecting guilds can help preserve ecosystem balance by maintaining critical functional groups.
- Guilds in Aquatic Ecosystems – Example: Filter-feeding guild in oceans includes baleen whales, manta rays, and some fish.
Additional Information
Option (2) Taxonomic Order (Incorrect):
- A taxonomic order groups species based on evolutionary relationships, not resource usage.
Option (3) Community (Incorrect):
- A community consists of all species in an ecosystem, interacting at different trophic levels.
Option (4) Assemblage (Incorrect):
- An assemblage refers to species living in the same area but without considering resource use.
