1)
In ecosystem, the term invasive species refers to:
Native species
Non-native species
Can be both native and non-native species
None of the above
2)
It is too difficult to identify the invasion of Asian long-horned beetle at the early stage. The reason is:
They hide in the crevices of tress
They are nocturnal species
They attack the leaves and cannot be easily recognizable
They burrow deep inside the heartwood of a tree
3)
Characteristic feature(s) of an invasive species
Natural mechanisms of rapid dispersal
Disrupt a particular habitat
Dominant colonization
All the above
4)
Invasion of Sea lamprey threats the population of
Mastacembelus armatus
Salvelinus namaycush
Anguilla rostrata
Polyodon spathula
5)
An example for a biological control agent to reduce the species invasion in ecosystem
Amitrol
Asecodes hispinarum
Brontispa longissima
Giant salvinia
6)
The rate of the spread of pest population depend (s) on
Number of native species
Rate of population growth
Temperature
Adaptation of the new species to a particular area
