How does matter and energy cycle through the living and nonliving parts of an ecosystem?
In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.
What is the cycle of matter in an ecosystem?
The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher level consumers when they eat lower level consumers. When living things die, the cycle repeats.
How does matter cycle through a living system?
Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat.
Does matter flow or cycle?
Energy and matter are often cycled within a system, and different forms of matter and energy are able to interact. The surrounding environment must be considered when studying a system’s energy and matter to examine flow into and out of the system.
How can models matter and energy cycle through an ecosystem?
Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level.
