Question
The species of plants that plays a vital role in controlling the relative abundance of other species in a community is called _______.
alien species
endemic species
exotic species
keystone species
, certain key species are essential because they drive major ecosystem functions . This concept is illustrated by the 'rivet popper hypothesis', which suggests that the loss of these specific species poses a far more serious threat to the stability and functioning of the environment than the loss of others . Furthermore, the sources note that some species help maintain species diversity in a community by reducing the intensity of competition among other species, thereby controlling their relative abundance . While the sources use the term 'key species,' the term keystone species in the options refers to this functional role. In contrast, alien species are non-native organisms that may become invasive , and endemic species are those confined strictly to a specific geographical region .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Excretory Products and their Elimination . Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
