      • It has big ears to reduce body temperature because their blood vessels are very close to their skin and so favour heat dissipation. It is nocturnal.

      • It is adapted to cold temperatures and they have thick fur and a layer of fat. They also hibernate.

      • It is a plant that has adapted to hot temperatures. It has narrow, long leaves.

      • It is a decidous tree that has lost its leaves for the autumn and winter seasons.

      Why can we see lizards sunbathing during spring?

      • This is because lizards are homeothermic animals, so their body temperature is dependent on the environment's temperature. The warmth provided by sunlight makes the lizards more active.

      • Correct answer

      Why can we find many epiphytes in tropical forests?

       

      Epiphytes in a beech forest
      • In tropical forests, there are so many tall tress that barely any rainwater reaches the ground, so to carry out photosynthesis, some plants (epiphytes) have to climb on the trunks of larger trees to collect rainwater.

      • Correct answer
        Wrong answer
      • In tropical forests, there are so many tall tress that it gets quite warm at ground level, so to carry out photosynthesis, some plants (epiphytes) have to climb on the trunks of larger trees to keep cool.

      Why is having an increased number of red blood cells an adaptation to high altitudes?

      • At high altitudes, the concentration of oxygen is lower. As a result, the transportation of oxygen in the blood has to be more efficient. The increase in red blood cells increases the efficiency of oxygen transportation in an organism.

      • Correct answer
        Wrong answer
      • At high altitudes, the concentration of oxygen is lower. As a result, the organism consumes more energy and more red blood cells with more oxygen are needed.

      • Correct answer
        Wrong answer
      • At high altitudes, the concentration of oxygen is higher, so organisms produce more red blood cells.

      Oxygen is more soluble at low temperatures. What are the consequences of this for aquatic organisms? Complete the sentence to answer.

      Aquatic organisms take oxygen from the water in the form of dissolved oxygen molecules. As oxygen is more soluble at low temperatures, there is oxygen available and therefore life is abundant.

      Is it possible for a freshwater fish to live in the sea?

      • No. The salt cancentration in the sea is too high for a freshwater fish. It will become dehydrated.

      • Correct answer
        Wrong answer
      • No. The temperature in the sea is higher than in a river, so the freshwater fish will die of heat.

      • Correct answer
        Wrong answer
      • Yes, all freshwater fish can adapt to live in an environment with a higher salt concentration.

      And for a saltwater fish to live in a river or lake?
      • No. The salt cancentration in a river is too low for a saltwater fish. Too much water will flow into them, causing its cells to burst or stop working.

      • Correct answer
        Wrong answer
      • No. The temperature in the sea is higher than in a river, so the saltwater fish will freeze.

      • Correct answer

      • Yes, all seawater fish can adapt to live in an environment with a lower salt concentration.

      Turtles that live in tropical areas do not hibernate. Why?

      • Some turtles are dominant over others and they do not let them hibernate.

      • Correct answer
        Wrong answer
      • In tropical areas, there are no cold seasons in which food is scarce, so the turtles are active all year round and do not need to hibernate.

      • Correct answer
        Wrong answer
      • Because they are capable of maintaining their body temperature all year round, whether it is cold or warm.

      Why have large predators adapted to spending long periods of time without food?

      • Because hunting is a difficult activity that is not always successful.

      • Correct answer
        Wrong answer
      • Because food is always available, so it's a waste to use energy continuously hunting.

      • Correct answer
        Wrong answer
      • Because the prey they hunt gives them enough energy to use and store for a long period of time.
