Diversity
Step-by-step explanation:
The increase in plant species diversity allowed increase in species diversity of insects
Increase in plant species defines that more plant species live in grasslands and forests as a result the more insect species find a habitat there
The presence of more plant species does not only increase insect species richness, i.e. the number of species, but also insect abundance, i.e. the number of individual
Similarly, animal diversity is not only determined by plant diversity, but also by the physical structure of the plant communities
