Hi there!
Sustainability means that something or someone has the ability to keep something going.
For example, a plant could have good life sustainability because it has a special poison, keeping predators away from it.
You could be self sustainable by growing your own crops, collecting your own water, and making things you need.
Hope this helps!
Primary succession occurs when a natural disaster like an EQ, volcanic eruption, or flood, occurs to an area where there is no plant or animal life. The first organisms to appear are lichens, which over a long period of tome, will begin to form soil.

I believe the correct answer is upwelling. Lets say we have producers such as plankton. well upwelling currents bring dead matter from the ocean floor up to the surface, creating plankton.
