Answer:
The correct answer will be - Keystone species
Explanation:
Keystone species refers to the species present in a community which has a large effect or great influence on the surrounding environment.
The concept of Keystone species was introduced by the Robert T. Paine in 1969 to the species which help maintain the structure of the biological community.
The keystone species are called keystone species as its presence affect the other organisms directly and if removed from a community it will lead to the shift or change in the structure of the community.
Thus, Keystone species is the correct answer.
The culprits for the degradation of local biological communities on Macquarie Island are the rabbits, rats,mice and cats that were non-native species were introduced by humans.
The introduction of non-native species to Macquarie Island was responsible for severely degrading the local biological communities, including the vegetation, birds, and invertebrates that were native to the island. The introduction of rabbits, rats, cats and mice led to the loss of native plants, while cats and pigs preyed on native birds and invertebrates. These introduced species caused extensive damage to the local ecosystem, resulting in the loss of native species and the decline of the island's biological diversity.
The new species competed for resources and habitat, and often preyed upon the native species. This had a devastating impact on the local ecosystem, and led to the decline of many native species. The introduction of rabbits was particularly damaging, as they caused widespread destruction of the native vegetation. This had a knock-on effect on the birds and invertebrates that depended on that vegetation for food and shelter. The decline of the native species has had a significant impact on the biodiversity of Macquarie Island, and has resulted in the loss of many unique and valuable species.
These species have wreaked havoc on the island, preying on native birds and other small animals, as well as destroying vegetation. The impact of these introduced species has been so severe that the island has been declared a World Heritage Site. In order to protect the remaining native species on the island, a eradication program was launched in the 1990s to get rid of the introduced animals. While this program has been successful in reducing the populations of these animals, they continue to pose a threat to the island's ecosystem.

Explanation:
<em>A diagram of a Punnett Square showing the chromosomes involved in the inheritance of sex-linked traits.
</em>
<em>The female had the genotype XHXh, and produced the two gametes seen at the left side of the diagram.
</em>
<em>The male had the genotype XHY0, and produced the two gametes seen at the right side of the diagram.
</em>
<em>The genotypes seen in the center of the square represent the possible genotypes of the F1 generation.
</em>
<em>Two female offspring are produced for every two male offspring.
</em>
<em>One male and one female offspring inherit normal genes.
</em>
<em>One female is heterozygous for the hemophilia trait and is considered a carrier.
</em>
<em>One male receives a damaged X-chromosome and inherits the condition known as hemophilia.</em>
