Soils are classified based on their structure, origin, and composition. They are formed from pieces of rock (rocky soils), sand (sandy soils), clay (clay soils), mixtures of sand and loam (sandy-loamy soils), or decayed organic materials (muck soils). Terrestrial ecosystems include flowering and non-flowering plants that grow in different soil types, while decomposers like fungi and bacteria break down organic matter. Aquatic ecosystems contain plankton, algae, and plants adapted to aquatic environments, and receive organic matter from terrestrial ecosystems through rivers and lakes.

5. The balance between plants and abiotic factors like water and air
determines the distribution of different plant species in ecosystems.
TERRESTRIAL ECOSYSTEM
In this ecosystem, flowering and non-flowering plants grow in
different kinds of soils. Decomposers like fungus and bacteria change
organic matter.

AQUATIC ECOSYSTEM
In this ecosystem, plankton, algae and plants adapted to the aquatic
environment grow. The relationship between soil and the aquatic ecosystem
is caused by the organic matter that is carried from terrestrial ecosystems
by the rivers to the oceans and lakes.
Terrestrial and aquatic ecosystems depend on each other since the energy
flows between both ecosystems to maintain the balance and the
sustainability of the biotic and abiotic factors.

7. A group of microscopic organisms which live in salt or sweet water,
more abundant up to 200 meters of depth.

8. A very large and diverse group of organisms, ranging from
unicellular to multi-cell forms such as the giant kelp, a large brown
alga that may grow up to 50 meters in length.
