AQUATIC ECOSYSTEMS
It is a community of living things that live in a particular place and the relationships between them.
Ecosystem
These are the four main factors that affect terrestrial ecosystems.
Temperature, humidity, relief, and soil
This term refers to the variety of living things on Earth.
Biodiversity
These are the most important protected areas created by authorities to look after ecosystems.
National parks
This is a simple way to look after ecosystems at home by taking short showers instead of baths.
Saving water
These are the two main types of aquatic ecosystems, classified by the amount of salt in the water.
Freshwater and saltwater ecosystems
This is the name for the shape of the land, which can be flat or steep.
Relief
These two ecosystems are the most biodiverse in the world and home to half of all known species.
Rainforests and coral reefs
Authorities identify these types of animals because they are in danger of extinction and need survival plans.
Endangered species
These are the most important protected areas created by authorities to look after ecosystems.
National parks
In this type of freshwater ecosystem, water moves fast at the source and slows down at the mouth.
Flowing water (like rivers)
It is the layer of the ground where plants grow their roots and take in water and mineral salts.
Soil
This occurs when a species disappears forever from the whole world.
Extinction
This is something people can do at home with their rubbish to help the authorities protect the environment.
Recycling
Authorities identify these species because they need special survival plans to avoid disappearing.
Endangered species
This factor determines which organisms can live in an aquatic ecosystem and it decreases as the depth increases.
Sunlight
This factor mainly depends on the amount of rain in an area; animals and plants need it to live.
Humidity
These are the three main causes of extinction according to the sources.
Destruction (of habitat), pollution, and hunting/overfishing
Authorities create these to limit activities that can harm nature, such as hunting, fishing, or construction.
Protection laws
This is a daily action we can take at home by putting our rubbish into different bins.
Recycling
These saltwater areas are shallow, have a lot of light, and contain multicellular algae attached to the seabed.
Coastal areas
On Earth, temperature is highest at this location and falls as we move towards the poles.
Equator
When these specific organisms in an ecosystem become extinct, the consumers cannot eat and also face extinction.
Producers
This is a simple action people can take at home by taking shorter showers instead of baths.
Saving water
This is an action authorities take to protect forests from being destroyed by flames.
