biology unit 1- adaptions for survival

Adapt and survive

• To survive and reporduce organisms need materials from the surroundings and from other organsisms living there
• plants- light, co2, oxygen, water and mineral ions
• animals- food, water and oxygen
• adaptions-special features of an organism that make it especially well adapted to live in is environment
• adaption examples- plants= big leaves to increase photosyntheis, animals=sharp teeth for predators to eat meat
• most organisms live in temp less than 40' so enzymes can work but the ones that live in conditions above this are called EXTREMOPHILES as enzymes would usually denature
•  cool conditions= small SA to volume ratio so they can preserve heat
• hot conditions= large SA to volume ratio so they can loose heat

• plants can loose water through holes in the…
