Answer: TRUE.
Explanation: A food chain refers to the feeding relationships between species in a biotic community. In a food chain, the series of organisms is dependent on the next as a source of food.
A food web refers to a diagram showing the organisms that eat other organisms in a particular ecosystem, predators being higher in the web than their prey. In a food web, there's an interconnection of food chains and a graphical representation of what-eats-what.
An organism that feeds at the top of a food chain is more vulnerable to ecological collapse because of the depletion of a particular feeding population than one that feeds at the top of a food web.

It dissolves atmospheric carbon dioxide and prevents global warming.

Panthalassic Ocean
Explanation:
During the time at which the last super-continent Pangaea existed, there was an enormous ocean as well. This ocean was stretching from one side of Pangaea to the other side of it, circling the rest of the planet that was not covered with land. The name that was given to this ocean is the Panthalassic Ocean. It has to be mentioned though that it was not the only ocean during this time though, as there were two other much smaller oceans, the Paleo Tethys Ocean and the Tethys Ocean, both being located between the land masses that later gave birth to Eurasia and Australia. Because of the size of the Panthalassic Ocean it was capable of producing much stronger storms and waves that the human kind had ever witnessed, and it is certain that those storms and waves were doing enormous damage along the coastline of Pangaea.
