3. What is an
ecosystem?
An ecosystem is a system formed by a set of organisms, the
physical environment in which they live (habitat) and the
relationships between living organisms and the physical
space established between them. The species of living beings
that inhabit a given ecosystem interact with each other and
with the environment, determining the flow of energy and
matter that occurs in that environment.

4. How are the
organisms of an
ecosystem
classified?
In an ecosystem there are a large number of organisms
with many different functions. There are 3 categories of
organisms in ecosystems: producers, consumers and
decomposers.
5. 01. Producers
They are autotrophic organisms,
that is, they are capable of
generating their own food from
simple substances with the help of
sunlight. They are the basis of the
food chain.
Classification of
organisms
6. 02. Consumers
These are heterotrophic organisms, which means that they do
not have the capacity to manufacture their own food, so they
feed on other beings.
They can be classified as:
● Primary consumers or herbivores
● Secondary consumers or carnivores
● Tertiary and quaternary consumers or super carnivores
Classification of
organisms
7. 03. Decomposers
These are organisms that feed on
decomposing organic matter from
other living organisms.
Classification of
organisms
9. Terrestrial ecosystem
They occur on the earth's crust and out of water in
various types of relief: mountains, plains, valleys,
deserts. There are important differences between
them in temperature, oxygen concentration and
climate, so the biodiversity of these ecosystems is
large and varied. For example: Forests, deserts or
jungles.
Types of
ecosystems
10. Aquatic ecosystem
They are characterized by the presence of water as the
main component and are the most abundant type of
ecosystem: they constitute almost 75% of all known
ecosystems. This group includes the ecosystems of the
oceans and those of fresh or salty inland waters. For
example: rivers, lakes and lagoons.
Types of
ecosystems
11. Mixed ecosystem
These are ecosystems located in areas of "intersection"
of different types of terrain, for example, in which
aquatic and terrestrial environments are combined.
Mixed ecosystems, also called hybrids, share
characteristics of both terrestrial and aquatic
ecosystems, and are considered transition zones
between both types of ecosystems.

ecosystems
13. Characteristics
of an ecosystem
1. They vary in size and structure according to their type.
2. They can be terrestrial (in reliefs such as desert, mountain, prairie), aquatic (fresh or
saltwater) or mixed (such as those found in wetlands).
3. They can be natural or artificial (created and/or intervened by humans).
4. They are dynamic and variable environments that experience natural or artificial changes
and a constant flow of energy and nutrients between the factors that constitute them.
5. They are complex systems due to the interactions among their members. The greater the
biodiversity, the greater the complexity of the ecosystem.
6. They can be altered naturally (such as natural catastrophes) or by human action (such as
deforestation, pollution and indiscriminate fishing).
