Final answer:
Decomposers such as fungi and bacteria break down the dead organism and release nutrients back into the environment, which can be taken up by plants for growth.
Step-by-step explanation:
Decomposers such as fungi and bacteria are the organisms in an ecosystem that recycle the nutrients trapped in an organism when it dies. These decomposers break down the dead organism and release nutrients back into the environment. The nutrients can then be taken up by plants and used for growth. This nutrient recycling is essential for the stability of the ecosystem.
