All LIVING THINGS need each other to survive. LIVING THINGS are food for other living things.
When they die, fungi, bacteria and worms release their remains back to the soil

In a FOOD CHAIN, each living organism gets food from other living organisms Produce their own food
plants
PRODUCERS
animals CO
fungi, bacteria...

from the soil, air and the
S ER M U S N
Sun's energy
PREYS are eaten by other animals (predators)
DECOMPOSERS
Get food from other living things
PREDATORS capture and eat other animals (preys)
Eat dead animals and plants. They release nutrients back to the soil

Example of forest food chain... Snails eat plants. They are a prey for birds
Birds eat sails. They're a prey for foxes
CONSUMERS
Foxes eat birds. They are predators
PRODUCER Plants produce their own food from the soil, air and energy from the Sun
Bacteria decompose the remains of all these living things and return organic matter back to the soil
DECOMPOSERS

Example of ocean food chain... Dolphins get food from small fish
CO
Orca whales eat dolphins
N SU M ER S
Small fish eat zooplankton
DECOMPOSER
PRODUCER Phytoplankton formed by algae that produce their own food
El Tomillar, J.C. Brazo
Zooplankton gets food from phytoplankton
Bacteria and other microorganisms decompose the remains of living organism and return organic matter back to the sea

ADAPTATIONS
Living things need to adapt to their environments in order to survive
Physical
Behavioral
adaptations
adaptations The chameleon changes its color
Some birds migrate from one place to another
are changes in an animal's body that helps it to find food, defend itself
are changes in an animal's behavior that helps it to interact with it's habitat
and reproduce

A HABITAT is a place that gives an organism food, shelter, water, oxygen and a place to live.
LAND HABITATS: - DESERTS - RAINFORESTS - GRASSLANDS - FORESTS - ARTIC REGION
El Tomillar, J.C. Brazo
WATER HABITATS: - OCEANS and SEAS - PONDS, LAKES and RIVERS

SEAS and OCEANS
RIVERS: Streams of running
We find: Saltwater fish

Some birds
PONDS: Small area of water.
Small invertebrates
This water doesn't move (like in rivers)
