Question

Invasion of alien species disrupts ecosystem processes. Justify.

Answer 1

The alien species disrupt ecosystem processes, because

1. They threaten biodiversity, reduce native herbs, reducing ecosystem services (benefits).
2. They only alter the ecosystem and micro intimate by prolific spreading.
3. They also alter the nature of the soil and make it unsuitable for native species.
4. They create human health problems like allergies.
5. Thus they degrade the local environment and eliminate important local species.
