The effect of changing environments is commonly asked in I/GCSE Biology!!!! SO LET'S GET STARTED! 😛

• 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

• UK – changing weather each season or direction of wind
• Organisms in UK cope with this change
• Short term changes

1. freak storms (flooding) or extreme temperature ➡️ kills organisms

• Long term conditions

1. climate change

In I/GCSE Biology, it'd be better to memorize the effect of changing environment on birds and on bees!

• 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)

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
