Question

Based on the text, what would Loch Ness need to support a plesiosaur? A food source, warmer waters, and a large plesiosaur population A warm climate, access to the sea, and cleaner water More salmon, less silt, and a larger body of water More access to the sea, deeper waters, and more research salmon

Answer 1

A food source, warmer waters, and a large plesiosaur population

Step-by-step explanation:

in the texts it says that

Tropical waters: Scientists believe plesiosaurs were warm-blooded. Like crocodiles and alligators, plesiosaurs would need to live in warm waters. The loch is very cold with temperatures averaging about 40 degrees Fahrenheit (4.4 Celsius).

Food: Like other warm-blooded creatures, plesiosaurs would need a large quantity of food. If there is a group of Nessies, then even more food would be needed. Because the loch is full of silt (underwater dust) not much light gets into the deepest areas. So the food chain, which would depend on plankton, is very weak at its base. As a result, there is probably not enough food to support such a large creature.

this is how you get your answer.

Answer 2

In order for Loch Ness to support a plesiosaur it would need a bigger food source, a bigger plesiosaur population and warmer waters. In order for there to be a Loch Ness monster there would need to be a whole population of plesiosaurs to reproduce and survive. There are only about 22 tons of fish in the lake and that is not enough to support a large breading plesiosaur population. Also the lake is too cold for a plesiosaur said to be a warm-blooded animal to survive.
