An ecosystem consists of three main components: the habitat, the living things within it, and the relationships between them. The habitat includes non-living elements like rocks, soil, water and air that provide characteristics like temperature and humidity. All parts of an ecosystem are interconnected, as living things depend on each other and their habitat for survival. Ecosystems maintain balance when all relationships, such as producers making their own food, consumers eating other organisms, and decomposers breaking down waste, are functioning properly. However, human activities like overconsumption of natural resources and pollution are disrupting ecosystems.

An ecosystem is a combination of three
components: a place or habitat , the living
things that live there and the relationships
between them.

3. THE PLACE OR HABITAT:
●
HABITAT: The habitat is made up of all of the nonliving components . For example : rocks ,soil ,
water and air .
●
Different characteristics : temperatures , season and
humidity,different types of water or soil,ect .
●

4. RELATIONSHIPS
Everything is connected in an ecosystem . Living
things depend on each other and on the
characteristics of their habitat . When all of the
relationships in an ecosystem are working well,
we say that the ecosystem is in balance .

5. FEEDING RELATIONSHIPS
Living things in an ecosystem are classified as
producers , consumers or descomposers
depending on how they get their food .

6. PRODUCERS
Plants and algae ,in aquatic ecosystems , are
producers . Producers make their own food .

7. CONSUMERS
Animals are consumers . Consumers feed on
other living things in the ecosystem . Herbivores
eat producers , carnivores eat other consumers
and omnivores can eat producers, consumers
and decomposers .

8. DESCOMPOSERS
Fungi and microscopic organisms called bacteria
are descomposers .

9. NATURAL RESOURCES
Natural resources are all of the things from the
Earth’s ecosystem and use to meet our needs .
