Population

International migration



Nowadays, in Spain and in other countries people need to emigrate because of different reasons. Life can be difficult for them. We should help them to adapt to their new country, and respect each other.
You can see here some examples of children who emigrated from their countries.

Thanks to Asier, Adrián Molina and Lucas for these power points. They will help you understand trophic relationships.




How does human activity affect our environment? Daniela will show you.

Types of ecosystems:
1.   Natural ecosystems: develop without human intervention. i.e.: oak forest.
Depending on factors like geographical relief, types of soil and climate we find:
-         Aquatic: fresh water as lakes and salt water as oceans.




-         Terrestrial: the most important factors are light, temperature, humidity and type of soil. i.e.: deciduous forest.

2.   Humanized ecosystem: exist because of human intervention. i.e.: cities, farms…

Would you recognise these invertebrates?




Check if you were right! Watch the following power point

Let's review invertebrates!



4. PLANTS


Characteristics:
- They are multicellular. Their cells have a rigid cell wall.
- They interact with their environment but don't move around.
- They make their own food (autotrophs)



Seed plants: angiosperms and gymnosperms.





Non-seed plants: they produce special cells called spores.

Bacteria belong to the monera kingdom

6. PROTISTA

LIVING THINGS



We can find lots of didderent living things in our planet. We are going to learn about them and how they are organised.





1. Life on Earth.

The Biosphere  is the global sum of all ecosystems. It's the layer around Earth which holds life. There, we can find different types of organisms such as plant and animals.

All living things carry out the trhee life processes:
. 1 Interaction: living things detect information in their environment and react to it in different ways. Human beings use our sense organs to detect information; we communicate with each other, we move around and do many things.
. 2 Nutrition: living things take in essential nutrients from their environment. These provides them with the energy they need to grow and develop. We carry out nutrition by breathing, drinking water and eating food, as well as eliminating waste products.
3. Reproducction: it consists of creating new members of their own species, There are different types of reproduction. Human beings are mammals, so woman give birth to babies and they produce milk to feed them.
