ecology project

habitat study

For my project i decided to study the grassland habitat around my house

flora present

• dandelion
• buttercup
• daisy
• grass - clover
• deciduous and evergreen trees

fauna present

• earthworms
• wood lice
• spiders
• foxes
• red squirrels
• sparrows, robins, crows

competition in forest ecosystem

• smaller trees must compete with larger ones for light and nutrients in the soil
• dandelions compete with other plants for space for reproduction

for my habitat study experiment i used a (homemade) quadrat to carry out a quantitative study of the grassland

this is a picture of the habitat i used

FLORA PRESENT IN THE QUADRAT

• grass
• buttercups
• daisies
• clover

there were no fauna present so i began to look for some

by lifting rocks i found earthworms and wood lice

abiotic factors

• light intensity - this can effect the growth of plants in certain areas of the habitat
• soil type - this can effect the growth of certain plants. if a solid is sandy it allows easy root penetration.
• pH of soil - this can effect the growth of plants. if a soil is too acidic it can be hard for plants to grow.

biotic factors

• food - the more food available, the more organisms that will be present.
• competition - animals and plants fight for a scarce resource. this can lower the number of weaker organisms.
