Question

plants absorb nutrients from soil, and nutrients help plants grow. which level of organization best describes this interaction between plants and soil?
○ community
○ ecosystem
○ organism
○ population

Explanation:

• A community refers to interacting living organisms only, not including non-living components like soil.
• An ecosystem includes both living organisms (plants) and non-living abiotic factors (soil, nutrients) and their interactions.
• An organism is a single individual living thing, which does not describe the plant-soil interaction.
• A population is a group of the same species, not involving non-living elements.

The interaction between plants (living) and soil (non-living with nutrients) matches the definition of an ecosystem.

Answer:

B. ecosystem
