BIOLOGY; Miller and Levine; Prentice Hall;2006


Energy flow in the biosphere

_______________________ _____________

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

BIOLOGY; MIller and Levine; Prentice Hall; 2006


Energy flow in the biosphere

absence of light

Some autotrophs can make own food in the ____________________

They use energy stored in

________________ of

______________________to produce

carbohydrates = ___________________

Ex: Bacteria that

live in HOSTILE places

Like volcano vents, hot springs,

marshes

chemical bonds

INORGANIC MOLECULES

CHEMOSYNTHESIS

Heterotrophs get energy from consuming other organisms

CONSUMERS

HETEROTROPHS = ____________Get energy from consuming other organisms

Heterotrophs consumers

HETEROTROPHS = CONSUMERS

HERBIVORES

________________ =

eat only plants

________________ =

eat only animals

________________ =

eat both plants & animals

CARNIVORES

OMNIVORES

Heterotrophs consumers1

HETEROTROPHS = CONSUMERS

DETRITIVORES

________________ =

feed on plant & animal remains

EX: mites, earthworms,

snails, crabs

________________ =

break down and absorb organic matter

EX: bacteria & fungi

Energy flow in the biosphere

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

In most ecosystems feeding relationships are more complex

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

FOOD WEB


Energy flow in the biosphere

TROPHIC LEVEL

Each step in a food chain or web =

_______________

______________

ALWAYS

make up the

________

trophic level.

PRODUCERS

FIRST

Energy flow in the biosphere

Lower levels must be

bigger to support the

level above.

Only about_____ of

the energy from

each level is passed

on.

10%

Energy flow in the biosphere

Some energy is used

for life processes

such as growth,

development,

movement,

metabolism,

transport, and

reproduction.

The rest is

lost as ________

HEAT
