Sample NECO SSCE Biology 2004 questions

1. In most terrestrial plants, through which structures does most water vapour leave the leaves?
  1. Stomata
  2. Lenticels
  3. Root hairs
  4. Xylem vessels

Answer: A. Stomata

Most transpiration occurs by diffusion of water vapour through open stomata.

2. Why is less energy available to organisms at each successive trophic level in a food chain?
  1. Energy is created by decomposers
  2. Organisms use energy in metabolism and lose much of it as heat
  3. Producers absorb all energy from consumers
  4. Energy is recycled completely as mineral salts

Answer: B. Organisms use energy in metabolism and lose much of it as heat

Respiration, movement and other life processes transfer much of the energy to the surroundings as heat.

3. A lichen consists of a fungus and an alga living together, with both partners benefiting; this is an example of
  1. parasitism
  2. competition
  3. mutualism
  4. predation

Answer: C. mutualism

  1. Nitrosomonas
  2. Penicillium
  3. Lactobacillus
  4. Rhizobium

Answer: D. Rhizobium

Rhizobium bacteria in legume root nodules convert atmospheric nitrogen into nitrogen compounds usable by the plant.

5. What is assimilation in human nutrition?
  1. The incorporation and use of absorbed nutrients by body cells
  2. The mechanical breakdown of food in the mouth
