  • Statement 1: "Different plant species grow together" refers to a diverse range of plant species growing in the same area, which is characteristic of equatorial moist evergreen forests. These forests have a high level of biodiversity.
  • Statement 2: "Light cannot penetrate into the lower strata full of undergrowth" suggests that the canopy of trees is dense and thick, preventing light from reaching the forest floor. This is a feature of equatorial moist evergreen forests, where the canopy is typically dense, and the understory is shaded and full of undergrowth.

In equatorial moist evergreen forests, such as those in the Amazon or Congo basins, the combination of diverse plant species and a dense canopy that blocks light from reaching the forest floor fits the description provided in the question.

The other options do not fully match these characteristics:

  • (B) Tropical deciduous: These forests shed leaves during dry seasons, unlike evergreen forests, and usually have more sunlight reaching the ground during the dry season.
  • (C) Mediterranean: Characterized by hot, dry summers and mild, wet winters, typically with shrubs and small trees, not dense canopies or constant undergrowth.
  • (D) Warm temperate broad-leaved deciduous: These forests have seasonal leaf shedding, and while they may have some shading, they do not have the same level of dense undergrowth or biodiversity as equatorial forests.

Thus, the correct answer is (A) Equatorial moist evergreen.
