ECOSYSTEMS

BIOMES

BIOSPHERE

All the organisms that

live in a place together

with their NON-living

environment

Group of ecosystems

that have same climate

and similar communities

The portion of the planet

in which all life exists

IMAGE SOURCES: see last slide


The earth is solar powered
The Earth is SOLAR POWERED!

ALL LIVING THINGS USE ENERGY

_____________ is the main source of energy for life on Earth.

SUNLIGHT

Autotrophs producers can make their own food
AUTOTROPHS = PRODUCERSCan make their own food

ALL LIVING THINGS USE ENERGY

Most autotrophs use _______________

to capture solar energy

Main producers on land

= green plants

In water = algae

PHOTOSYNTHESIS

absence of light

Some autotrophs can make own food in the ____________________

They use energy stored in

______________________to produce

carbohydrates = ___________________

Ex: Bacteria that

live in HOSTILE places

Like volcano vents, hot springs,

marshes

chemical bonds

Heterotrophs get energy from consuming other organisms

CONSUMERS

HETEROTROPHS = ____________Get energy from consuming other organisms

HETEROTROPHS = CONSUMERS

HERBIVORES

________________ =

eat only plants

HETEROTROPHS = CONSUMERS

DETRITIVORES

________________ =

feed on plant & animal remains

EX: mites, earthworms,

snails, crabs

________________ =

break down and absorb organic matter

EX: bacteria & fungi

Energy flows through an ecosystem in a series of steps in which organisms transfer energy by being eaten

FOOD CHAIN

In most ecosystems feeding relationships are more complex

Pearson Education Inc, Publishing as Pearson Prentice Hall which organisms transfer energy by being eaten

In most ecosystems feeding relationships are more complex

A ______________ links ALL the food chains in an ecosystem together.

FOOD WEB


TROPHIC LEVEL which organisms transfer energy by being eaten

Each step in a food chain or web =

_______________

______________

ALWAYS

make up the

________

trophic level.

PRODUCERS

FIRST

Lower levels must be which organisms transfer energy by being eaten

bigger to support the

level above.

Only about_____ of

the energy from

each level is passed

on.

10%

Some energy is used which organisms transfer energy by being eaten

for life processes

such as growth,

development,

movement,

metabolism,

transport, and

reproduction.

The rest is

lost as ________
