Explanation
The correct answer is (D) All of the above levels.
Biodiversity can indeed be studied at multiple levels, including the species level, genetic level, and ecosystem level.
(A) At the species level, biodiversity involves studying the variety and abundance of different species within a given area. It includes identifying and cataloging different species and understanding their distribution and interactions.
(B) At the genetic level, biodiversity focuses on the genetic variation within species. It involves studying the genetic diversity, hereditary traits, and genetic adaptations that contribute to the overall biodiversity.
(C) At the ecosystem level, biodiversity encompasses the study of interactions between different species and their environment. It includes examining the variety of ecosystems, their functioning, and the ecological processes that support biodiversity.
By studying biodiversity at these different levels, scientists can gain a comprehensive understanding of the complexity and importance of biological diversity on Earth.
