Marine Ecosystems.

Learning Objective:

• We will describe food webs within marine ecosystems.

Marine Ecosystems

Marine ecosystems are aquatic environments with high levels of dissolved salt, such as those found in or near the ocean. Marine ecosystems are defined by their unique biotic (living) and abiotic (nonliving) factors.

Multiple Choice

What is a defining feature of Marine Ecosystems?

• Ships.

• Salt.

• Snakes.

Marine Ecosystems

Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature.

Multiple Select

What are important abiotic factors dissolved in Marine Ecosystems?

• Salt.

• Oxygen.

• Nutrients.
