Question

How does sunlight help tropical ecosystems develop relatively more vibrant flora and fauna?

• A. Most animals are diurnal and thus, found in regions with more sunlight
• B. Sunlight generates heat, which is needed for plants and animals to grow
• C. Sunlight is the primary source of energy from which all biomass is created on Earth
• D. None of the above

Answer 1

The correct option is C

Sunlight is the primary source of energy from which all biomass is created on Earth

Sunlight is the primary source of energy for all life forms on earth. Since the tropical region is exposed to more sunlight than any other region, the area receives an abundance of solar energy, which promotes the growth of plants. As the flora of a region expands in number, the fauna also expands, as an abundance of vegetation apparently, makes it a favourable habitat to live in.
