a.

Broadleaf plantains (Plantago major):

  • are low-growing perennial rosettes
  • require light for photosynthesis
  • absorb water and mineral ions through fibrous roots from soil
  • can tolerate high soil compaction but are eaten by invertebrate herbivores like slugs.

Give two abiotic factors and two biotic factors that could affect the population size of broadleaf plantains.

b.

Students investigated the population of broadleaf plantains in two different areas of a public park:

  • Area A: a heavily trampled dirt footpath
  • Area B: a nearby untrampled lawn area

Plan an investigation using a 0.5 m×0.5 m0.5 \text{ m} \times 0.5 \text{ m}0.5 m×0.5 m quadrat to compare the mean number of broadleaf plantains per m2\text{m}^2m2 in Area A and Area B.
