Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil.

<h3>What is the anatomy of Earthworm?</h3>
- An earthworm is a terrestrial invertebrate and a member of the phylum Annelida.
- They have a tube-within-a-tube body structure, corresponding external and internal segmentation, and typically include setae on each segment.
- They can be found wherever the soil, water, and temperature permit.
- The body of an earthworm is composed of a digestive tube and a thick cylindrical muscular tube that forms the body.
- The body is divided into segments, and furrows on the surface of the body serve as markers for the segment boundaries.
- The top of the first segment, which encloses the mouth, is a lobe made of muscle and flesh.
