The document summarizes key concepts about ecosystems and biodiversity. It defines producers as living things that produce their own food, and consumers as living things that eat other living things like primary, secondary, and tertiary consumers. Decomposers are living things that decompose remains of plants and animals. Food webs and food chains show how species are connected through their food relationships. The document also discusses how loss of biodiversity occurs through extinction and some of the human causes of reduced biodiversity like climate change, pollution, and habitat alteration. Protecting biodiversity includes creating national parks and biosphere reserves.

2. • The biosphere is the largest ecosystem because it is
made up of plaet Earth and all the living things.
• living in an ecosystems can be…….

3. • PRODUCERS:
Living things that produce their own food from
sunlight water and minerals salts from the soil (plants and
algae).

4. • CONSUMER
• Linving things that eat other living thing ( animals).
• PRIMARY COSUMERS:are animals that eat plants (
herbivores as rebbits, and insect as grasshoppers)
• SECUNDARY CONSUMERS: are animals that eat
herbivores animals (owls, foxes)
• TERTIARY CONSUMERS: are animals that eat secondary
consumers (hawks)
PREDATORS
Are carnivorous
animals that hunt
other animals (lions)
SCAVENGERS
Are carnivorous
animals that eat the dead
bodies of other animals
(vultures)
PARASITES
Feed of living things
without killing them
(mosquitoes)

5. • Living things that decompose the remains of other plants
and animals so the minerals of these living things return
to the soil (fungi and bacteria)
FOOD WEBS are a
conbination of various food
chains
FOOD CHAINS show how
the species in an
ecosystem are connected
to one another by their
food relationships

6. • Loss of biodiversity EXTINCTION occurs when every single
member of a sepcies dies and none are left
alive
Ex.Dinosaurs,
flyying reptiles and
the golden toad in
Costa Rica.
CAUSE
S
• Humans are rensposible for
most of the recent loss of
biodiversity in the world.
• Climate change.
• Pollution.
• Hunt and capturing animals.
• Over- exploting resources.
• Releasing pets into the wild.
• Alteration of habitatns
Protectig
biodiversity
Endangered
species are
those which are
in danger of
excenting .
National paks and
bioshpere reserves are
created to prodec
wildlife and its
environment.
