B1.4 adaptation 0.0 / 5 ? BiologyAdaptations of organisms to their environmentGCSEAQA Created by: LauragreeenCreated on: 09-04-17 11:10 What 5 things to plants need to survive? Light, carbon dioxide, water, oxygen and nutrients 1 of 20 What 3 things do animals need to survive? Food from other living organisms, water and oxygen 2 of 20 What are adaptations? Features that make it possible for an organism to survive in its particular habitat 3 of 20 How do plants produce glucose? Photosynthesis 4 of 20 How are epiphytes adapted to live high above the ground? They collect water and nutrients from the air through their leaves 5 of 20 How do some sea birds remove the salt they do not need after drinking sea water? By 'crying' very salty tears through special glands 6 of 20 What is an extremophile? An organism with variations to live in extreme environments 7 of 20 What are microorganisms that can survive very high temperatures called, and how are they adapted? Thermophiles - they have specially adapted enzymes 8 of 20 How are extremophiles who live in very salty conditions adapted? Their cytoplasm is adapted so that water doesn't leave the cell 9 of 20 What is the amount of heat energy you lose related to? Your surface to volume ratio 10 of 20 Why are deserts very difficult places to survive in? It's very hot in the daytime but cold at night, and there's very little water 11 of 20 Why does keeping cool in the desert pose more problems to mammals? They need to keep a constant body temperature but they can't sweat 12 of 20 What are the small openings in leaves called that allow gas exchange for photosynthesis, and what is lost through them? Stomata lose water by evaporation 13 of 20 Where can plants store water? In their tissues 14 of 20 3 things animals compete for: Food, mates and territory 15 of 20 What is an animal's territory? A place to find food/reproduce 16 of 20 Why do some plants flower earlier in the year? There's plenty of light that gets in through the bare branches 17 of 20 What does the distribution of living organisms depend on? Environmental conditions - light, pH and local climate 18 of 20 What factor determines the distribution of aquatic animals? Oxygen levels 19 of 20 How can you measure environmental change? (2 methods) By looking at non-living indicators, or at the changing distribution of living organisms 20 of 20
