The reason that coniferous forests mainly comprise of evergreen coniferous trees is:
Correct answer: D. Short summer season
- A. Low altitude
- B. Heavy rainfall
- C. Highly fertile soil
- D. Short summer season
Explanation
The correct answer is that coniferous forests mainly comprise evergreen coniferous trees due to the short summer season. In the regions where these forests are found, summers are brief and winters are long and harsh. By keeping their leaves year-round, these trees can take advantage of the limited growing season to photosynthesize whenever conditions are favorable. The other options are not correct: coniferous forests are not typically associated with low altitudes, heavy rainfall, or highly fertile soils. Instead, they thrive in higher altitudes/latitudes, moderate to low rainfall, and poor, acidic soils.

About Ecosystems
An ecosystem consists of organisms interacting with one another and with abiotic factors such as light, water, soil and temperature. The topic covers populations and communities, food chains and webs, trophic levels, ecological pyramids, energy flow, nutrient cycles and ecological succession.
