Answer:
<em>The nutrient cycle </em><em>is nature's recycling system. All forms of recycling have feedback loops that use energy in the process of putting material resources back into use. </em><em>Recycling</em><em> in ecology is regulated to a large extent during the process of decomposition.</em><em> Ecosystems employ biodiversity</em><em> in the food webs that recycle natural materials, such as mineral nutrients, which includes water. </em><em>Recycling in natural systems</em><em> is one of the many ecosystem services that sustain and contribute to the </em><em>well-being</em><em> of human societies.</em>

The species was a keystone species.
Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.
