Sample NECO SSCE Biology 2010 questions

1. Why is less energy usually available at each successive trophic level in a food chain?
  1. Producers consume all energy before herbivores feed
  2. Energy is recycled completely between organisms
  3. Organisms use much energy in respiration and lose some as heat
  4. Decomposers prevent energy from entering food chains

Answer: C. Organisms use much energy in respiration and lose some as heat

Respiration, movement, and other life processes dissipate much of the energy as heat at each trophic level.

2. In the food chain grass -> grasshopper -> frog -> hawk, which organisms are secondary consumers?
  1. Frogs
  2. Grasshoppers
  3. Grass
  4. Hawks

Answer: A. Frogs

Frogs feed on the primary consumers, the grasshoppers, so frogs are secondary consumers.

3. Which organism commonly fixes atmospheric nitrogen in the root nodules of leguminous plants?
  1. Nitrosomonas
  2. Pseudomonas
  3. Penicillium
  4. Rhizobium

Answer: D. Rhizobium

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

4. What is an important role of decomposers in an ecosystem?
  1. They convert sunlight directly into animal biomass
  2. They break down dead matter and release mineral nutrients
  3. They remove all carbon from the atmosphere
  4. They prevent nutrients from returning to the soil

Answer: B. They break down dead matter and release mineral nutrients

Decomposers break down dead organisms and wastes, returning mineral nutrients to the environment.

5. Which factor is most likely to limit plant growth in a very dry desert?
  1. Availability of water
  2. Availability of oxygen in the air
  3. Length of the day in every season
  4. Presence of gravity

Answer: A. Availability of water

In a desert, limited water restricts photosynthesis, cell expansion, and other processes needed for plant growth.
