Ecology
The
ECOLOGY
is the Science
that studies the
ECOSYSTEMS
and the interaction between living things and their environment.
wHAT IS AN
ECOSYSTEM?
The ecosystem includes:
Biotic components or BIOCENOSIS
: all the living things in an area. (Animals, plants, microorganisms, fungi...).
Abiotic components or BIOTOPE
: the non-living things of the environment. (Sunlight, air, soil, minerals, rocks, clouds, water, temperature...)

Lets do an activity:
Levels of organization
Define feeding relationships
in what we call a FOOD WEB
Food webs can be
represented by
pyramids
of numbers
of biomass
comparision
of energy
comparision
The end
Put an A or B in the circles to name the ABIOTIC (A) and the BIOTIC (B) components of this ecosystem. There are 12 circles.

In an ecosystem, there are the following levels of organization:
1) Individual / Organism
2) Population
3) Community
4) Ecosystem
5) Ecosphere

ECOSPHERE
ECOSYSTEM
POPULATION
ORGANISM
One single living thing,
(For example: a fox)
Group of the same organisms in an area. They reproduce, protect themselves, eat together...
(For example: a group of foxes)
COMMUNITY
Groups of populations of different species that live together.
(For example: foxes, rabbits, plants, birds, snakes...)
All living and non-living things in an area.
( For example: foxes, rabbits, plants, snakes, birds, mountains, sun, water...)
The planetary ecosystem.
It includes:
All living things on Earth (
Biosphere
).
All non living things (
Atmosphere
,
Hidrosphere
and
Geospher
e).
Flow of energy and food
In an ecosystem, living things need food and energy to survive.
There are three types of living things depending on the way they feed and get energy:
PRODUCERS.

CONSUMERS
DECOMPOSERS




Living things
Producers
Consumers
They get energy from the
sun
and use it to make their own food.
They get energy from
other living things
and cannot make their own food
Primary consumer
Secondary consumer
Tertiary consumer
Decomposers
- They get energy from other
dead living things
and decompose them
- They eat plants.
- They eat other animals
- They eat plants and animals
Ex.: Plants, algae...
Ex.: Bacteria, fungi...
Ex.: Herbivores
Ex.: Carnivores
Ex.: Omnivores
Here we have some activities:

FOOD CHAINS
Food chain is the order of how one living thing eats and gets energy from another.



It shows how energy passes from one to other.
The arrows show the direction of energy flow.
