The energy is needed for new growth, but the nutrients are recycled from the "old growth" from the older & diseased plants and animals dying. That puts their nutrients back into the system. So all it really needs is a constant supply of energy. Our biosphere, the Earth, is just a giant ecosystem that recycles all its nutrients, which can be considered as raw materials, that are used to build new life. If we look at the way we handle our "nutrients" like product that we buy every day, we can get a good picture of how wasteful it is to throw things away. We throw away so much plastic that they end up in the ecosystem and harm or kill the animals in it. There is a report that says that every cow in India has an average to 10 plastic bags in its stomach when it dies.
Ecosystems need a continual influx of new energy to sustain new growth. Nutrients to support this new growth comes from dead and dying plants that are re-used.

Unlike the one way flow of energy, matter is recycled within and between ecosystems.
it gives us life to us and to all the living organisms
Humans are able to use their knowledge to locate resources they need.
Most ecosystems have plants. Plants use the sun to create food and start the food chain. Without the sun, there would be no plants, thus no herbivores to eat the plants, thus no carnivores to eat the herbivores, so on and so on.
Yes, rockets need energy for launching
Temperature is the average kinetic energy of molecules, what we experience as warmth is the influx of energy. For ice to melt, it would need energy/heat; it would take this from it's immediate surroundings.

All Ecosystems need it one way or another

The world needs invertebrates because they are an important part of ecosystems.
