The document defines an ecosystem as a biological system consisting of a community of living organisms and their physical environment. It provides examples of ecosystems like tundra, desert, grasslands, and forests. Specifically, it describes tundra as the polar biogeographic region with low-growing vegetation beyond wooded areas, and notes animals in the Arctic tundra include caribou, musk oxen, Arctic hares, Arctic foxes, snowy owls, lemmings, and polar bears near water sources. It also defines producers, consumers, decomposers, populations, communities, and habitats as key components of an ecosystem.

 The ecosystem is a
biological system made
up of a community of
living organisms and the
physical environment
where they are related.

-Tundra.
-Grasslands.
-Tropical rainforest.
-Coniferous forests.
-Temperate decidious forests.
-Mediterranean forests.

4. TUNDRA
The tundra is described as the polar
biogeographic region, the vegetation of
which is low growing beyond the northern
limit of the wooded area.
Los animales notables en la tundra ártica
incluye el caribú (reno), el buey almizclero,
la liebre ártica, el zorro ártico, el búho
nival, los lemmings y los osos polares (solo
cerca de las masas de agua alimentadas
por los océanos).

5. PRODUCERS
A living thing that can make
its own food.
Plants, trees, flowers…

6. CONSUMERS
A living thing that gets its
food from eating other living
things.
A grizzly bear eating fish, a snake
eating mice.

7. DECOMPOSERS
Decomposers are organisms that
break down dead or decaying
organisms, they carry out
decomposition, a process
possible by only certain
kingdoms, such as fungi.

8. POPULATION
A group of living things
that
live in the same place at
the
same time.
Many lions living in a
savannah.

9. COMMUNITY
When different populations
live together in the same
habitat and interact with
each other.
Elephants,lions, and
zebras all live together in
the Savanna.

10. HABITAT
A habitat is a home
environment for plants and
animals or other organisms.
Desert, meadow, woodland.
