Blue-green algae are found to have survived in a crater left by a space rock that struck Earth millions of years ago. The said crater led to the formation of what is now known as the Gulf of Mexico. Scientists from Curtin University in Australia found out that cyanobacteria must have been present by the time of impact when geologists dug into the crater in 2016. Cyanobacteria are microorganisms that live within plants’ cells and can produce food for the plants. Aside from cyanobacteria, scientists also found other living organisms in the rocks from the tsunami that followed the incident.
True or False:
- The blue-green algae lived in the space rock.
- The crater formed the Gulf of Mexico.
- The cyanobacteria produce food for the plants.
- Scientists from South America found out about the cyanobacteria’s presence.
- Scientists did not find other living organisms within the rocks.
