In an eco-system, all animals and insects are important. Since there is no picture, I'll descibe what would happen. If a keystone species went missing or extinct, shortly after the rest of the ecosystem will callapse. The bird population would decrease because lack of food, shelter or environment, then those who feed on birds will slowly decline, then worms or insects that the bird was keeping in check, overpopulate. This can have disaterous consequences, not only for this specific ecosystem but for any.

Carbon can form single, double, and triple bonds with other carbon atoms.
When we drinks water, those little droplets on the outside of the glass are condensation. I think?
Nutrients including sulfur and Phosphorus move through the ecosystem through a biogeochemical cyclic process. Chemical elements move via a pathway, that is termed as a biogeochemical cycle. Those move by means of the biotic and the abiotic components of the ecosystem.
Hope this helps !!
