question 10
1 pts
another component transferred within an ecosystem is not considered
ecyclable\ and must be continuously obtained since it is used at each level. what is it?
○ matter
○ energy
○ sunlight

Explanation:

First Question (above Question 10)

The definition given (anything with mass and takes up space) matches matter. Sunlight is a form of energy and has no mass/volume in the same way, and energy doesn't have mass or take up space. So matter is cycled in ecosystems.

Question 10

Energy flows through ecosystems (not recycled) and needs continuous input (e.g., from sun). Matter is cycled, and sunlight is a source of energy, not the non - recyclable component itself. Energy is used at each trophic level and not recycled, so it must be continuously obtained.

Answer:

A. matter
