Question

Given four causes of loss in biodiversity. Explain the adverse effects on native species on an invasion of alien species in a habitat.

Answer 1

Hint:Biodiversity is the abundance and heterogeneity at all levels of living organisms, namely land, marine and other aquatic ecosystems and their ecological complexes. Biodiversity loss is defined as the decrease in the number of genes, individual organisms, species, and habitats in a given environment.

Complete answer
To answer this question, we have to understand details on BiodiversityAround the world, biodiversity is decreasing at a very fast rate. Humans have begun to rule the world over the last century, causing rapid ecological change and significant loss of biodiversity around the Earth.

Major direct threats to biodiversity include
>habitat loss and fragmentation,
>unsustainable resource use,
>invasive species,
>pollution, and global climate change.

As people aspire for more prosperous lifestyles, the root issues of biodiversity depletion, such as rapid human population growth and overconsumption, and decreased resource quality, are also nuanced and stem from several factors.

Alien species are non-native species that are found in new surroundings when introduced. They become invasive and have detrimental effects on native biota, causing native species to collapse or even become extinct, and influencing ecosystems negatively. The species comprises mammals, plants, fungi and microorganisms that have penetrated and developed themselves beyond their natural habitat in the environment. They grow rapidly and compete for food, water and habitat with native species, and are one of the primary contributors of the loss of global biodiversity.

The foreign species of plants that have infiltrated India and caused environmental harm are Parthenium, Lantana, and Eichhornia. They pose a significant threat to many of our native species' existence.

Note:Typically, biodiversity is a measure of variability within organisms, between species and ecosystems. Genetic diversity, species diversity and habitat diversity are the three significant components of biodiversity.
