Define foreground, mid ground and background plants aquatic science

Hope I managed to help in parenthesis my own ideas

Explanation:

-Foreground aquarium plants are ideally aquatic plants that are placed at the base of a hardscape layout, near the midground area. Alternatively, foreground aquarium plants are also referred to as carpeting plants.(small close to the ground usually bushes or small plants.(weigela, moss)

- Midground aquarium plants are ideally aquatic plants that are placed in the midground at a medium height of a hardscape layout. These plants really help to fill in the central focal point of a planted tank.(Medium size plants(sunflower) or small trees(new oak tree))

- A background plant is a type of plant that provides a backdrop for smaller plants. A hedge can be a type of background plant design, if the hedge is lined with smaller flowers.(huge 200+ old trees dominating the forest)

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
