What is the relationship between matter and energy in an ecosystem?

Question

A. Matter and energy show the feeding relationships in an ecosystem
B. Matter and energy are cycled through the ecosystem
C. There is no relationship between matter and energy in an ecosystem
D. Matter and energy can only be modeled through food webs

Answer 1

The most accurate answer is:

B. Matter and energy are cycled through the ecosystem

In an ecosystem, matter (such as nutrients) and energy (from sunlight or food) are essential components that are constantly exchanged and transformed. Energy flows through the ecosystem largely in a linear way—from producers to consumers—and is ultimately lost as heat. Meanwhile, matter is recycled through processes like decomposition and nutrient cycling.
