Answer:
Rats - Virgin Island
Hemlock - Asia
Zebra moulds - Great Lakes
Explanation:
An alien species is one that was introduced into a new environment, but does not have harmful effects. Such alien species are considered invasive species as they begin to have harmful effects on the new habitat. Invasive species can cause damage to the ecosystem, economic harm or human health effects.
Three invasive species are as following:
- Rats that came on board ships to the Virgin Islands infested the islands' sugar cane fields and caused significant crop damage.
- The woolly adelgid hemlock is an invasive Asian insect which rapidly kills infested hemlock trees.
- Zebra moulds in the Great Lakes can easily cover submerged surfaces, obstructing water intakes at water treatment plants and power plants
Answer: Decomposers are the final link in a food chain or food web. Decomposers break down organic matter and release nutrients into the soil

Answer: i dont know the question
Explanation:
If the temperature is too low, enzyme molecules don’t have enough kinetic energy to collide and combine with other substrate molecules. So the enzyme activity/ reaction rate will be very low. The rate will rise again once the temperature increases to its optimum temperature.
But if the temperature is too high, enzyme will be denatured, which means the shape of the active site of the enzyme is changed. It can no long combine with other substrate molecules. The rate will drop significantly. Yet, lowering the temperature won’t help because denaturation is permanent and irreversible.
