FOOD CHAINS and FOOD WEBS VIDEOS

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

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:

Term	Description
Environment	All the conditions that surround a living organism
Habitat	The place where an organism lives
Population	All the members of a single species that live in a habitat
Community	All the populations of different organisms that live together in a habitat
Ecosystem	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:

                

Organism	How it gets its energy
Consumer	Feeding on other organisms
Primary consumer	Eating plants
Secondary consumer	Eating primary consumers
Tertiary consumer	Eating secondary consumers
Herbivore	Eating plants
Carnivore	Eating other animals
Omnivore	Eating both plants and animals
Decomposer	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.

SYMBIOSIS

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.

PLANTS

MAPS OF SPAIN

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!!!

MATTER

Here you have this video to revise what we've been learning about properties of matter.

Enjoy it!

CLIMATE AND WEATHER

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.

A CURIOSITY ABOUT THE GREENWICH MERIDIAN

If you travel to Greenwich, stand on the famous Prime Meridian Line -- which is marked with a physical line and a sculpture at the Royal Observatory -- and look at your GPS, it won't read 0° longitude. It'll be slightly out. Who's right? And why?
(Tom Scott)

FROM CELL TO SYSTEMS

Animals and plants are made of cells. Tissues are made from cells of a similar type. Organs are made from tissues, and systems are made from several organs working together. They all make up an organism.

cells - tissues - organs - organ systems - organism

If you want to know more details about how this organization takes place, watch this entertaining video.

CELLS - AN INTRODUCTION

Cells
Cells are very small. They are the basic building blocks of all animals and plants. 

Animal cells usually have an irregular shape, and plant cells usually have a regular shape

Cells are made up of different parts. It is easier to explain what these parts are by using diagrams like the ones below.

Animal cells and plant cells both contain:

• cell membrane, cytoplasm, nucleus

Plant cells also contain these parts, not found in animal cells:

• chloroplasts, vacuole, cell wall

The table summarises the functions of these parts.

Part	Function	Found in
Cell membrane	Controls what substances can get into and out of the cell.	Plant and animal cells
Cytoplasm	Jelly-like substance, where chemical reactions happen. In plant cells there's a thin lining, whereas in animal cells most of the cell is cytoplasm.	Plant and animal cells
Nucleus	Controls what happens inside the cell. Carries genetic information. In exams don't call the nucleus the 'brain' of the cell. That is not a good description and will not get you marks.	Plant and animal cells
Chloroplast	Where photosynthesis happens – chloroplasts contain a green substance called chlorophyll.	Plant cells only
Vacuole	Contains a liquid called cell sap, which keeps the cell firm.	Plant cells only
Cell wall	Made of a tough substance called cellulose, which supports the cell.	Plant cells only
