Question

Select the statement that is an example of a species providing an ecosystem service.

1) After mice invaded a home, the homeowner used humane traps to release the mice into the wild.
2) Deer promote biodiversity and natural balance by over-mating.
3) When a whale is injured, other whales will support it out of the water so it can breathe.
4) Earthworms aerate the soil and create pathways for root growth under farmers' fields.

Answer 1

The statement exemplifying an ecosystem service is that earthworms aid in aerating the soil and creating pathways for root growth, which is vital for agriculture and biodiversity.

Step-by-step explanation:

Selecting the statement that exemplifies a species providing an ecosystem service involves identifying a contribution made by an organism to the environment that benefits other organisms, including humans. From the options given, the statement that represents this best is:

• Earthworms aerate the soil and create pathways for root growth under farmers' fields.

This statement describes the role of earthworms in soil structure and fertility, which is a key ecosystem service. Earthworms enhance soil aeration and drainage, and promote nutrient cycling by breaking down organic matter. This activity improves soil quality, which is crucial for plant growth and, consequently, for productivity in agriculture. Such contributions are essential for the maintenance of healthy ecosystems, supporting biodiversity and the services that humans derive from the natural environment.
