BiologyAdaptations of organisms to their environmentGCSEAQA Created by: KAustriaCreated on: 04-06-14 21:52 What do planets need in order to survive? 1. light 2 carbon dioxide 3. water 4. oxygen 5. mineral ions 6. nutrients 1 of 28 What do animals need in order to survive? 1. food from other organisms 2. water 3. oxygen 2 of 28 What are adaptations? Special features organisms which help hem survive in their environments- even if they are extreme 3 of 28 What are extremophiles? microorganisms which are adapted to live in conditions were enzymes won't usually work because they would denature 4 of 28 How are animals in cold climates adapted to their environments? They have thick fur and fat under the skin to keep them warm. 5 of 28 How are animals in the arctic adapted to their environment? Their skin changes colour from brown to white to that they are able to camouflage so that they are unable to be seen. 6 of 28 How are large animals able to conserve their energy? They have large surface areas compared to ratio, however this means that they are unable to cool down quickly. 7 of 28 Describe animals living in warm climates in terms of their SA:V and explain how this helps them. Animals in hot dry dry areas have a large area to volume ratio so that heat can be easily lost and therefore they are able to cool down. 8 of 28 Describe animals living in cold climates in therms of their SA:V and explain how this helps them? Animals in cold climates have a small surface areas to volume ratio so that they are able to conserve thermal energy within them. 9 of 28 Where do plants lose water? Through their stomata in their leaves 10 of 28 How can plants coolect water? Through extensive root systems. 11 of 28 How can plants have conserve water? 1,. Plant leaves have small or waxy leaves 2. Swollen stems so that they can conserve water. 12 of 28 How is a cacti adapted to conserving water? 1. Large swollen stem 2. Needles to stop animals from eating them 3. Very small stomata 13 of 28 How do plants prevent themselves from being eaten by animals? 1. Thorns 2. Poisonous chemicals 3. Warning colours 14 of 28 What are animals in competition for? water, food, space, mates and breeding sites. 15 of 28 Why do predators compete with their prey? Because they want to eat htme. 16 of 28 How do animals prevent themselves from being seen by their competition? Camouflage 17 of 28 How do animals prevent themselves from being attacked from competition? Poisonous chemicals. 18 of 28 How do plants spread their seeds? 1. Use animals to spread their fruits and seeds 2. explosions 3. mini explosions 19 of 28 Why do plants try to spread their seeds as afr as possible? So they do not compete with themselves. 20 of 28 Ho was femal fig wasps adapted to be successful competitors? 2. Specially shaped heads to insert into fig tree flowers 2. Oviposters that allow them to place eggs deep inside the flower. 21 of 28 How are the star-nosed mole and Venus fly trap adapted for survival? 1. Moles are very sensitive to touch and smell 2. Fly traps have a sweet,sticky nectar and are bright red inside to attract insects. 22 of 28 What are the non-living factors which might change that can effect organisms? 1. Temperature 2. Rainfall 3. Light 4. Oxygen 23 of 28 What are the living factors which might change that can effect organisms? 2. Arrival of new predator 2. disease 3, Introduction of new food or habitats. 24 of 28 How do Lichens work? 1. Indicate the level of sulfur dioxide in the atmosphere 2.The more lichens growing the cleaner the air. 25 of 28 How fdo freshwater inverterbrates indicate the level of water pollution? The wider the range of freshwater intervertebrates, the cleaner the water in the streams, rivers or pond. 26 of 28 What are lichens also known as? Indicator species 27 of 28 How does changes in the environment affect organisms? The distribution of these may change. 28 of 28
