Ecosystem study Flashcards
Name your habitat
Fota Wildlife Park- Woodland
Name and describe methods of collecting animals
Pooter- one end over animal and suck through other end.
Beating Tray- Place under bush and shake
Pitfall Trap-Jam jar in ground and cover with raised flat stone. Insects go under for shelter and fall in.
Sweep net- Sweep tall grass in figure of 8
Explain Qualitative and Quantitative studies
Quantitative-estimate number of plants and animals
Qualitative-estimate types of plants and animals
Name and describe quantitative method for plants.
Quadrat
Throw pen over shoulder, place quadrat on top, choose plants to study, record frequency and % cover, repeat and record results.
Features of a Quadrat
Random: throwing pen method.
Non-limited: can throw pen any direction.
Name and describe qualitative method for plants.
Line transect
Shows the different types of plants at different areas of the habitat.
Laid across habitat from a shaded area to a well lit area and the plants under each knot are counted.
Features of line transect
Non-Random: You decide where to place the transect.
Limited: Only measures a certain length of the habitat.
Name a Quantitative study for animals
Capture Recapture method.
Name a Qualitative study for animals
Key
Name 2 types of plants (flora) in your habitat Energy Flow role Adaption Abiotic Factor Eaten by
-Bramble Energy Flow role: producer Adaption: Bright tasty fruit for dispersal by birds. Spines protect and allow it to climb other shrubs. Abiotic Factor: Soil pH- 6 to 6.5 Eaten by: Blackbirds and Squirrels
-Ivy
Energy Flow role: Producer
Adaption: Adventitious roots enable it to climb tree to get more light.
Abiotic Factor: Light intensity- Can grow at low levels
Eaten by: Berries and Nectar eaten by birds in winter. Buds eaten by moth and butterfly.
Name 3 animals (Fauna) Energy Flow role Adaption Abiotic Factor Diet Eaten by
Ladybird
Energy Flow role: Secondary Consumer/ Carnivore
Adaption: Bright colours deter predators
Abiotic Factor: AIr temperature: determines length of life cycle
Diet: Aphids and other small insects
Eaten by: Swallows
Worm Energy Flow role: Decomposer Adaption: Moves through soil quickly Abiotic Factor: Soil moisture- can't move in dry weather Diet: Dead plant material Eaten by: Blackbird, Fox, Badger
Snail
Energy Flow role: Consumer/ Herbivore
Adaption: Produces mucus to prevent it drying out.
Abiotic Factor: Temperature- If high it will dry out.
Diet: Primrose leaves, Cabbage leaves
Eaten by: Hedgehogs, Badger
What is a Key
A series of questions you answer based on the animal you have collected.
Example of a food chain from the habitat
Berries-Blackbird-Fox
Grass-Rabbit-Fox
Leaves-Snail-Badger
Frequency formula
No. of Quadrats containing organisms divided by quadrats thrown.
Difference between frequency and % cover
Frequency- Records if plant is present in quadrat or not. Yes/No
% Cover- Number of times the plant is present in each quadrat. Express as a percentage of the quadrat.
