Answer 1

Invasive alien species are non-native species introduced into an ecosystem, which can negatively impact native biodiversity.

The effects of invasive alien species include:

• Competition with native species for resources, leading to population decline of native organisms.
• Alteration of habitat conditions, affecting the ecosystem balance.
• Predation on native species, leading to their extinction.
• Economic damage in agriculture and forestry.

Example: Water hyacinth and Parthenium in India.
