If they are plants (e.g. spotted knapweed) they produce seeds to reproduce, because they are plants that produce seeds to reproduce.
If they are animals (e.g. brown tree snake) they do not produce seeds, because animals do not reproduce by producing seeds.
Yes, bird vetch (Vicia cracca) is considered an invasive species in many regions, particularly in North America. It can spread rapidly, outcompeting native plants and disrupting local ecosystems. Its ability to thrive in various habitats and produce abundant seeds contributes to its invasive potential. Management efforts are often needed to control its spread in affected areas.
Pandas are not an invasive species.
A noxious weed is another term for an invasive plant species.

Plants produce seeds as a way to reproduce and spread their species. Seeds contain the genetic information and nutrients needed for a new plant to grow. This strategy allows plants to colonize new areas and ensure the survival of their species.
Plants produce fruit to protect and disperse their seeds, ensuring the survival and spread of their species.
In order to secure the and survival rate of next generation of that particular plant.
Ferns - they only produce spores not seeds. Fungi also produce spores not seeds. Some species of trees like Pussy Willow - Salix cinerea etc require a male tree to produce pollen or in this case catkins and only the female of the species produces seed.
