The effect of changing environments is commonly asked in I/GCSE Biology!!!! SO LET'S GET STARTED! 😛
Changing environments
- Difficult for organisms to live in a place where the conditions have changed
- Distribution ➡️ the area of the environment in which a specie lives
What's happened if the environment is changed?
- May be easy for other organisms to move in and compete
- May cause a change in the distribution of species
For example:
- UK – changing weather each season or direction of wind
- Organisms in UK cope with this change
- Short term changes
- freak storms (flooding) or extreme temperature ➡️ kills organisms
- Long term conditions
- climate change
In I/GCSE Biology, it'd be better to memorize the effect of changing environment on birds and on bees!
The effect on birds
- Some birds 🐦 expand their breeding range and to other continents
- Some birds 🐦 instead of migrating each winter stay year round as there is more insect food available
- Some species suffer from lack of food
- Average sea temperature raised by 1°C ➡️ scientists link to loss of sand eels (birds eat)
The effect on bees
Do you remember that we've talked about climate change in I/GCSE Biology before?
- Rapid decrease of bees 🐝 ➡️ wild + kept by beekeepers
- Can be due to climate change and loos of wildflowers ➡️ increased building + farming
- Hard for bees 🐝 to get food if there’s a cold, wet spring
- Warm wintersmite parasite 🐛 survive ➡️ destroyed bees 🐝 in hives
- Loss of range of plants ⬅️ due to farmers
