Question

the diagram shows the food web of an ecosystem. which of the following paths is followed by matter as it cycles through this ecosystem? sun - grass - robin plant seeds - field mouse - robin eagle - deer - plant seeds grass - deer - mountain lion

Explanation:

In an ecosystem, matter cycles through food - chains. Producers (like plants) take in matter and energy, consumers eat producers or other consumers. The Sun provides energy but is not matter. The correct path should start with a source of matter (producer) and follow a predator - prey relationship. Plant seeds are a source of matter for the field mouse, and the field mouse is prey for the robin.

Answer:

Plant seeds - field mouse - robin
