Question

1. how is the way matter moves through an ecosystem different from the way energy moves?

1. what are two ways that water moves from land into the air?

1. why do living things need nutrients?

Explanation:

1. Matter cycles (recycles) through an ecosystem, while energy flows in one - way (enters as sunlight, exits as heat).
2. Evaporation (water from land surfaces like lakes, rivers turns to vapor) and transpiration (water vapor released from plants).
3. Nutrients are needed for growth (building cells), repair (healing tissues), and carrying out life processes (e.g., metabolism).

Answer:

1. Matter cycles in an ecosystem, energy flows in one - way.
2. Evaporation and transpiration.
3. For growth, repair, and life processes.
