How does temperature affect the types of organisms in an area?

Answer 1

not really answering the question

an increase in temperature can lead to:

• can allow non-native species to enter the area, they may out compete the native species for food, light and space- a high profile example of this in the UK is the ring-necked parakeets
• may cause organisms to move into areas better suited to their range of tolerance- many species in the UK are moving Northward because of an increase in temperature
• new species may colonise the area- such as the egret in the UK
• earlier laying date for many common birds and amphibians
• earlier arrival and later deprature for migratory birds
• later leaf fall for many broad leaf trees in Autumn
• earlier appearance of toad stalls and mushroom in Autumn
• earlier leafing and flowering of many tree shrubs and flowering plants
• high sea water levels (due to land ice melting and thermal expansion of water) will cause increase erosion and flooding which is detrimental for low laying habitats such as wetlands

Answer 2

Temperature can influence the types of organisms in an area by determining which species can survive and thrive in that particular environment. Organisms have specific temperature ranges within which they can function optimally. Extreme temperatures can limit the diversity and abundance of species in an area as only those adapted to those conditions can survive.
