Ecosystems and Marine Science Concepts

define ecosystem

• An ecosystem is a community of living organisms and their physical environment interacting as a system.
• An ecosystem is a collection of non-living materials.
• An ecosystem is a single organism living in isolation.
• An ecosystem is a type of plant species.

define ocean

• A type of fish found in rivers.
• A small pond of freshwater.
• A large body of saltwater that covers most of the Earth's surface.
• A landmass surrounded by water.

define environment

• The environment is solely the climate and weather patterns.
• The environment refers only to urban areas and cities.
• The environment is a collection of all living organisms.
• The environment is the sum of all external conditions affecting living organisms.
