Soils: Deep soil layers, rich in nutrients
Precipitation: 30–100 in/yr in all forms (snow, rain, hail, fog, etc.)
Abiotic Factors Plant adaptationsDeciduous forests grow in layers
More sunlight reaches the ground compared to a rainforest so you will find more ground dwelling plants.

Estuaries • Streams and rivers merge with ocean water in areas known as estuaries. • Estuary organisms experience changes in salt concentration and temperature as
the fresh water and salt water mix. • Estuaries serve as breeding grounds for many invertebrate and fish species, and
as nesting and feeding areas for a great diversity of birds. • Along most of the east coast of the United States, the major ecosystems found in
estuaries are salt marshes. • In tropical areas, the typical estuary ecosystems are mangrove swamps. • These swamps are dominated by mangrove trees, which are anchored by tangled
networks of arching roots.

• The area of shore between the high-tide and low-tide lines. • Pounded by waves during high tide and exposed to the sun and drying winds
during low tide, benthic organisms in this zone must be well-adapted to survive these harsh conditions

Near Shore Zone • The area of the ocean from the low-tide line out to the edge of the
continental shelf. • Since the ocean here is fairly shallow, some sunlight reaches the
bottom in most of the zone. • As a result, many organisms that require light for photosynthesis can
live in this zone, including seaweeds and phytoplankton.

Open-Ocean Zone • The vast open ocean from the edge of the continental shelf outward. • Phytoplankton drifting near the surface are the major producers in this
zone. • Microscopic animals called zooplankton also inhabit this area and in turn
are a source of food for other animals.
