Lesson 6: The diversity of life

1.BASIC CONCEPTS.

Heterotrophic beings: They have to take food from other living beings.
Autotrophic beings. They can manufactured their own food, usually doing photosynthesis:

H2O + CO2 + sunlight-------> Organic matter + O2 (Animation)

All living beings are made up of cells, some living beings are unicellular and some beings are pluricellular.
There are two kinds of cells: procaryotic and the eucariotic cells.

4. CLASSIFICATION INTO SMALLER GROUPS.

A species is a set of beings which are physically similar and which reproduce among themselves and produce fertile descendants.
Each scientific name includes two words: Homo sapiens, Passer domesticus, Pistacia lentiscus...
Several species can be joined into a genus, several genus are grouped into a order, orders into a class, classes into a type and finally types are grouped into a kingdom.
