Flora of the Woodland
(Sessile Oak)
•
Role in energy flow: Producer
•
Adaptation: Sheds its leaves in winter to conserve water which might not be readily
available. If leaves were present, water would be lost by transpiration.
•
Abiotic factor: Soil pH: Grows best in Acidic soils pH 4 – pH 6.5.
•
Eaten by: Aphids and caterpillars eat the leaves. Squirrels eat the acorns.
Flora of the Woodland
(Holly)
•
Role in energy flow:
Producer
•
Adaptation:
Able to photosynthesise in lower light
intensity as its dark green leaves have a
high level of chlorophyll to maximise
light absorption.
•
Abiotic factor:
Percentage soil water:
Intolerant of wet soil.
•
Eaten by:
Red berries eaten by blackbirds.
Flora of the Woodland
(Bramble)
•
Role in energy flow:
Producer
•
Adaptation:
Brightly coloured succulent fruits for
dispersal by woodland birds. Spines on
leaves and stems protect the plant and
act like hooks and helps the plant to
climb other shrubs.
•
Abiotic factor:
Soil pH: Grow best at a pH of 6 – 6.5
•
Eaten by:
Berries eaten by blackbirds and
squirrels.
Flora of the Woodland
(Ivy)
•
Role in energy flow:
Producer
•
Adaptation:
Adventitious roots enable it to climb up
trees in order to reach better light.
•
Abiotic factor:
Light Intensity: Can grow at low light
intensity.
•
Eaten by:
Berries and nectar provide winter feed
for birds. Buds are eaten by the larvae
of moths and butterflies.
Flora of the Woodland
(Bluebell)
•
Role in energy flow:
Producer
•
Adaptation:
Flowers early in spring and
completes its life cycle, before the
canopy of leaves emerge and
reduce the available light.
•
Abiotic factor:
Light Intensity: Needs high light
intensity to flower.
•
Eaten by:
Bulbs are eaten by badgers. Bees
eat the nectar from the flower.
Flora of the Woodland
(Lords and Ladies)
•
•
•
•
Role in energy flow:
Producer
Adaptation:
It produces a pungent smell (like rotting meat) to attract flies for pollination.
Abiotic factor:
Light Intensity: Shade tolerant, will survive at low light intensities.
Eaten by: Not eaten, it is a poisonous plant.
Flora of the Woodland
Primrose
•
•
•
•
Role in energy flow:
Producer
Adaptation:
Flowers early in spring before the
leaves appear on the trees which
block the light.
Abiotic factor:
Light Intensity: Needs high light
intensity to flower.
Eaten by:
Slugs, snails, and butterflies feed
on the nectar.
Flora of the Woodland
Bracket Fungus
(not a plant)
•
Role in energy flow:
Decomposer
•
Adaptation:
Can obtain its nutrients from dead
and decaying wood.
•
Abiotic factor:
Humidity: It thrives in high
humidity.
•
Eaten by:
Slugs
Fauna of the Woodland
(Blackbird)
•
Role in energy flow:
Consumer
•
Adaptation:
Pointed beak for probing the ground to
find earthworms. Low notes in its song
travel very well through the woodland.
•
Abiotic factor:
Air temperature: If the temperature is
low, it can lead to high mortality in the
young due to open nests.
•
Feeds on:
Ivy berries and other fruits. Also eats
insects and worms.
•
Eaten by:
Fox
Fauna of the Woodland
(Snail)
•
Role in energy flow:
Consumer / Herbivore
•
Adaptation:
Its ability to produce a slimy mucus
prevents the snail drying out as it
travels across dry terrain.
•
Abiotic factor:
Humidity: If the humidity is low it
is in danger of drying out, it thrives
in cool and moist conditions.
•
Feeds on: Plant material e.g.
primrose leaves
•
Eaten by: Hedgehog and Badger
Fauna of the Woodland
(Woodlice)
•
Role in energy flow:
Decomposer. Feeds on wood and leaf
litter.
•
Adaptation:
Grey/brown colour provides
camouflage to protect them from
predators.
•
Abiotic factor:
Air temperature: In high temperature
they tend to lose water quickly.
•
Feeds on: Wood and leaf litter.
•
Eaten by: Shrews, badgers and birds.
Fauna of the Woodland
(Badger)
•
Role in energy flow:
Consumer/ Omnivore
•
Adaptation:
Sharp claws used for digging
through the stony woodland soil to
build their sets.
•
Abiotic factor:
Air temperature: They become
inactive and sleep during very cold
weather.
•
Feeds on:
Slugs, earthworms, beetles, roots
e.g. bluebell roots.
Fauna of the Woodland
(Red Squirrel)
•
Role in energy flow:
Primary Consumer
•
Adaptation:
Long bushy tail is an aid to balance
on tree tops.
•
Abiotic factor:
Air temperature: They become less
active during very cold weather.
•
Feeds on:
Acorns, nuts
•
Eaten by: Fox
Fauna of the Woodland
(Aphid)
•
Role in energy flow:
Consumer / Herbivore
•
Adaptation:
Mouth parts are adapted for
sucking plant sap.
•
Abiotic factor:
Temperature: As the temperature
increases the aphids reproduce
faster.
•
Feeds on: Plant sap
•
Eaten by: Ladybirds
Fauna of the Woodland
(Ladybird)
•
Role in energy flow:
Secondary Consumer / Carnivore
•
Adaptation:
Bright colour deters predators
• Abiotic factor:
Air temperature:
determines the length of the life
cycle
•
Feeds on:
Aphids (Greenfly) and other small
insects.
Fauna of the Woodland
(Earthworm)
•
•
•
•
•
•
Role in energy flow:
Decomposers
Adaptation:
Can move through the soil quickly
Abiotic factor:
soil water. During periods of dry
weather they cannot move through
the soil. They travel deep into the
soil to avoid dehydration
Feeds on:
Dead plant material.
Eaten by:
Blackbird and Fox.
