  1. Complete the gaps: Biomass is… Draw a pyramid of numbers for the following food chain: grass > zebra > lion Where does the energy in a food chain originally come from? What is a trophic level? B1 Environment and Evolution What are the word and symbol equations for photosynthesis? An oak tree is infected with beetles; bacteria infect the beetles. A cornfield where field mice live; foxes prey on the field mice. An oak tree supports lots of bird life; the birds are hunted by foxes. What is the difference between a pyramid of numbers and a pyramid of biomass? Match the description with the pyramid of numbers

  2. What is a producer? To calculate biomass: Number of dry mass organisms x of one organism at trophic at that trophic level level Draw a pyramid of biomass for this food chain: Grass > zebra > lion 1 000 000 100 4 0.1 kg 300 kg 250 kg (one square = 1000 kg) What are pollution indicators? What are the best conditions for decay? B1 Environment and Evolution Name the sources of energy for: a) A plant b) a herbivore c) a carnivore What is a detritivore? What is a decomposer? Draw arrows to show how energy is lost and gained from this rabbit

  3. Fill in the Gaps The Carbon Cycle What is combustion? What are fossil fuels? What are extremophiles? Fill in the gaps: How is a camel adapted to where it lives? Light energy from the sun
