Q1) What is an invasive species?

An invasive species, often referred to as an invasive alien species or invasive exotic species, is a non-native organism (plant, animal, fungus, or microbe) that is introduced to a new environment, ecosystem, or habitat, where it spreads rapidly and causes harm to the local environment, economy, or human health. Invasive species are a significant ecological and economic concern worldwide because they can disrupt native ecosystems, displace native species, and lead to environmental degradation.
