Watch these videos to revise and learn about how we get energy, how one animal gets energy from another animal, or a plant. It's all about FOOD CHAINS and FOOD WEBS in this Crash Course Kids Compilation. (We thank them for the great job they're doing!)

Food chains and food webs describe feeding relationships. Organisms in an ecosystem affect each other’s population.
The table describes some common terms used to describe living things in their environment:

All the conditions that surround a living organism
The place where an organism lives
All the members of a single species that live in a habitat
All the populations of different organisms that live together in a habitat
A community and the habitat in which organisms live

A food chain shows what eats what in a particular habitat. It shows the flow of energy and materials from one organism to the next, beginning with a producer.
The Sun is the ultimate source of energy for most communities of living things. Green plants are usually the producers in a food chain.

Producers and consumers
A food chain always starts with a producer, an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis.
The other organisms in a food chain are consumers, because they all get their energy by consuming other organisms. So a food chain ends with a consumer, an animal that eats a plant or another animal.
Here is an example of a simple food chain:
grass → cow → human

The arrows in food chains show the way in which energy is moving. They do not show what eats what.

Other words in a food chain
There are several words used to describe the organisms in a food chain. Study this food chain:


How it gets its energy
Feeding on other organisms
Primary consumer
Eating plants
Secondary consumer
Eating primary consumers
Tertiary consumer
Eating secondary consumers
Eating plants
Eating other animals
Eating both plants and animals
Feeding on dead and decaying organisms, and on the undigested parts of plant and animal matter in faeces

Food webs
When all the food chains in an ecosystem are joined up together, they form a food web. Here is an example of a food web:

Although it looks complex, it is just several food chains joined together. Here are some of the food chains in this food web:
grass → insect → vole → hawk
grass → insect → frog → fox
grass → insect → vole → fox
Notice that:
·         the rabbits and slugs have just one predator
·         the frogs and voles have two predators (the foxes and hawks)
·         the insects have three predators (frogs, voles and thrushes)
This leads to some interesting effects if the population of a particular organism in the food web decreases. Some animals can just eat more of another organism if food is in short supply, while others may starve and die. This in turn can affect the populations of other organisms in the food web.

Here you have another example of a woodland food web:

The example above contains lots of information. Here are three food chains from it:
·         oak tree → squirrel → fox
·         oak tree → earthworm → wood mouse → fox
·         oak tree → earthworm → wood mouse → owl
The oak trees are the producers. Squirrels and earthworms are primary consumers, and the wood mice are secondary consumers. The foxes and owls are tertiary consumers (the foxes are also secondary consumers).

Foxes and owls eat the wood mice, and foxes eat wood mice and squirrels. The fungi and earthworms are decomposers in this food web.

You can find this information and more here, in BBC BiteSize


We've been studying about the relationship between animals from different species. Here you have the video we saw in class so you can revise these concepts:

- PARASITISM: the parasite benefits while the host is harmed.

- COMMENSALISM: one species benefits while the other is neither harmed nor helped.

- MUTUALISIM: both species benefit from the relationship.

Spain is made up of a total of 50 different provincies, all of them framed in 17 autonomous communities, plus 2 Autonomous cities (Ceuta and Melilla).

If you want to know their names, where they are and which ones are the capital cities of every province or community, just click on the following links, use the "learn bottom"(Mirar/Estudiar)  first and then feel free to play (Jugar/Practicar).

I hope you have a good time and learn a lot!!!

The next video is in Spanish but it explains in a simple and clear way the basic principles of the separation of powers that the Spanish constitution states.


I hope you have a better idea after watching it!!

You already know what the difference between climate and weather is. Here you have a simple definition of each one and the link to the video we watched during the lesson.

CLIMATE refers to the average weather pattern in one place over a long period.
WEATHER refers to the atmospheric conditions in a specific area at a specific time.

Weather versus Climate
Remember you can make the video go slower by clicking the gear icon and selecting 0.75 speed, as well as activating the subtitles!!

Today's videos are meant to revise vocabulary about illnesses as well as to learn why we get sick and how we can prevent it by following simple tips.
Enjoy them!
