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

LAND HABITATS animals and plants

Animals: Lizards and snakes, spiders, scorpions...

DESERTS Plants: cacti and resistant plants

Animals: Lizards, monkeys, parrots, etc RAINFORESTS Plants: Lots of trees and different plants

ARTIC

Animals: Polar bear, artic foxes, seals...

REGION Plants: No trees or plants Animals: Zebras, lions, cheetahs, antelopes...

GRASSLANDS Plants: Mainly grasses and only some trees FORESTS

El Tomillar, J.C. Brazo

Animals: Foxes, mice, owls, bears, rabbits, etc Plants: Evergreen trees mainly

SEAS and OCEANS

RIVERS: Streams of running

We find: Saltwater fish

water LAKES: Water with land all

Algae

Some birds

PONDS: Small area of water.

Small invertebrates

This water doesn't move (like in rivers)
