What is a habitat?
All living things live in a specific place. This is called a habitat. For example, a fish lives in a pond. The pond is its habitat.
Living things of the same species that live in the same habitat are a population.
The cactus population
The penguin population
What is a habitat?
All the different populations that live in the same habitat are a community. For example, the squirrel, rabbit and pine tree populations belong to the forest community. The populations in a community interact, for example, the squirrels eat the pine cones.
What is a habitat?
Habitats have different characteristics. The amount of light and water, the temperature and the type of soil all affect living things.
An ecosystem is the combination of a habitat and its community of living things.
HABITATS
Temperature is very important. If you take the monkey or the parrot from here to the South Pole, they will die very quickly!
Living things adapt to the characteristics of their habitats. There is lots of light here so there is lots of vegetation.
There is lots of water here. If you take a frog from here to a desert, it will die very quickly!
The type of soil is very important. Here the soil is very rich, so plants grow well.
What are the different types of ecosystems?
There are many different types of ecosystems, but we can classify them into two main groups: terrestrial and aquatic.
TERRESTRIAL AQUATIC
TERRESTRIAL ECOSYSTEMS
The most important characteristic of terrestrial ecosystems are light, temperature, water and the type of soil.
Mediterranean forests: Temperatures are warm. It doesn’t rain a lot, especially in summer. These forests are the habitat of many plants and animals.
TERRESTRIAL ECOSYSTEMS
Desert:
They are very hot and dry during the day and very cold at night. The soil is sandy or rocky. It almost never rains. Not many animals live here.
TERRESTRIAL ECOSYSTEMS
Rainforest: They are hot and wet. It rains a lot. Most land animals and plants on our planet live in rainforests.
TERRESTRIAL ECOSYSTEMS
North and South Pole: They are very cold. There is lots of snow and ice. Some animals, especially adapted to very low temperatures, live here.
AQUATIC ECOSYSTEMS
We can classify them into two types:
Fresh water ecosystems: Rivers, lakes and ponds are fresh water ecosystems. Plants like bulrushes and animals like fish, amphibians and birds live here.
AQUATIC ECOSYSTEMS
Salt water ecosystems: Sea and oceans are salt water ecosystems. Plants, algae and animals like fish, birds and aquatic mammals live here.
What are producers, consumers and decomposers?
In an ecosystem, living things eat and are eaten! They can be classified into producers, consumers and decomposers.
Producers are living things that make their own food.
Plants and algae are producers.
What are producers, consumers and decomposers?
What are producers, consumers and decomposers?
What are producers, consumers and decomposers?
Consumers are living things that eat other living things. Some eat only plants (herbivores), some eat only animals (carnivores) and some eat plants and animals (omnivores).
What are producers, consumers and decomposers?
Decomposers are living things that break down the remains of living things that have died and turn them into nutrients.
Bacteria and fungi, like mushrooms and mould, are decomposers.
What is a food chain?
The living things in an ecosystem make food chains and depend on each other for survival. A food chain is made up of at least one producer, one consumer and one decomposer.
How are ecosystems damaged?
In an ecosystem all living things are connected in a delicate balance. Any changes caused by humans can damage ecosystems. The main causes of damage are: forest fires, pollution, erosion and housing developments.
Forest fires: plants die and animals die or move away.
How are ecosystems damaged?
How are ecosystems damaged?
Air pollution: an increase in greenhouse gases is causing global warming. This results in unusual weather that damages ecosystems.
How are ecosystems damaged?
Water pollution: factories and boats dumping chemical waste in rivers and oceans damage and sometimes destroy ecosystems.
How are ecosystems damaged?
Housing developments: the building of large numbers of houses can damage ecosystems.
How are ecosystems damaged?
Erosion: cutting down trees for wood and paper or for agriculture can cause erosion. Erosion means fewer plants, and fewer plants means fewer animals. If erosion isn't controlled, the landscape can become a desert.
Caring for ecosystems
To protect an ecosystem we need to take precautions by: -Preventing fires. -Controlling the size and number of housing developments. -Making laws about dumping rubbish and chemical waste and making sure people follow them.
The Spanish lynx is an animal in danger of extinction. This means that people can't hunt it.
Reintroducing native plants is a way of helping a damaged ecosystem to recover.
