A species that is the top predator in its ecosystem
B
A species whose conservation protects other species in the same habitat
C
A species that is the most abundant in an ecosystem
D
A species that is introduced to control pest populations
Verified step by step guidance1
Understand the concept of an umbrella species: An umbrella species is a species whose conservation indirectly protects many other species within the same ecosystem. This is because the umbrella species often requires large habitats or specific environmental conditions that are shared by other species.
Differentiate between the options: The first option describes a top predator, which is not necessarily an umbrella species. The second option aligns with the definition of an umbrella species, as conserving it helps protect other species. The third option describes an abundant species, which does not imply conservation benefits for others. The fourth option refers to an introduced species for pest control, which is unrelated to the concept of an umbrella species.
Focus on the ecological role: An umbrella species typically has a significant ecological role that requires extensive habitat or specific conditions, thus its protection ensures the conservation of the broader ecosystem.
Consider examples: Common examples of umbrella species include large mammals like tigers or elephants, whose conservation efforts help protect the entire ecosystem they inhabit.
Conclude with the correct understanding: The correct answer is that an umbrella species is one whose conservation protects other species in the same habitat, as it requires large or specific habitats that overlap with those of other species.
