portugal

explanation:

portugal is the european country that is the westernmost country on the iberian peninsula.

tethys sea was an ocean during the mesozoic era .

this ocean was found between gondwana and laurasia.

the name of the ocean came from tethys the titan goddess of the primal font of fresh water which nourishes the earth.

the ocean was also know as neotethys.

the correct answer is - c) the ecosystem would be unable to recover after any event.

if in a certain ecosystem, lot of new species of plants and animals are introduced, and those plants and animals can survive in those conditions, than the ecosystem will experience dramatic changes and would never be the same again.

the new species, which will practically be invasive species, will start to compete with the native ones, and very often the invasive species come as tougher. the ecosystem will start to rapidly change, the native species will have much more competition and their numbers will dwindle, and in no time the whole ecosystem will be unrecognizable.
