If a zebra mussel is discovered in a lake in Pennsylvania, then the ecologist would be worried because it is an invasive species. The zebra mussel is native to Ukraine and Russia, but if it has been found in Pennsylvania, than it means that it has been introduced in this area. As an invasive species, the zebra mussel can be very dangerous for the native species in the lake. The invasive species usually are more competitive for food sources than the native species, manage to reproduce quicker, bring in diseases, and the native species tend to not have defense mechanisms for them. This leads to rapid decline or even extinction in the native species, while the invasive spreads out quickly and takes over, resulting in dramatic change in the whole ecosystem.

Answer:
True
Explanation:
Earth's radiation, that is, the energy that comes from the reflection, absorption, storage, and distribution from the Sun among the spheres play a major role in the climate systems.
The ultraviolet and visible energies from the Sun are the main drivers of the Earth's climate systems as the interaction between the particles of aerosol that are present in the atmosphere and the radiation from the Sun lead to the warming of the atmosphere.
Therefore, the answer is True.
