  1. What is the food chain called where it starts with dead or decaying matter?

  3. What does a thermometer measure?

    Answer: Temperature

    A thermometer measures temperature, usually in degrees Celsius (°C) in the UK. Digital and mercury/alcohol thermometers work by sensing heat energy. They are used in weather, cooking, and medicine.

  4. What type of skeleton do insects have?

    Answer: An exoskeleton (external skeleton)

    Insects have an exoskeleton — a hard outer shell (made of chitin) that supports and protects their body. Unlike vertebrates, the skeleton is on the outside. They must moult (shed) as they grow.

  5. Which organ removes waste products from the blood in the form of urine?

    Answer: Kidneys

    The kidneys filter waste products (particularly urea) and excess water from the blood. The resulting liquid (urine) passes to the bladder and is excreted. Humans have two kidneys.

  6. What is the name for the process by which water vapour cools and turns back into liquid water?

    Answer: Condensation

    Condensation occurs when water vapour cools and changes back to liquid water. You see it on cold windows or mirrors in a steamy bathroom. It is part of the water cycle.
