Answer 1

In biology, the term 'invasion' signifies the introduction and establishment of non-native species into a new ecosystem, often leading to detrimental effects.

Step-by-step explanation:

The term invasion refers to a process where a specific species, typically non-native, is introduced into a new ecosystem, where it establishes and spreads, often with negative ecological and economic impacts.

In the context of invasion biology, things like biological invasion, propagule pressure, and the invasion process involving transport, establishment, spread, and impact are critical to understand. For instance, the Indo-Pacific lionfish and the cane toad are both well-known invasive species that have had significant ecological consequences in areas they have invaded.
