Test: Ecosystem Characteristics - Year 11 MCQ

The Tropical rainforest biome is primarily located between 15 degrees north and 15 degrees south of the equator. This positioning is crucial for the unique climate conditions that support the diverse flora and fauna found in these regions. The equatorial climate provides the necessary warmth, sunlight, and rainfall that contribute to the incredible biodiversity of the tropical rainforests.

The Tropical rainforest biome occupies just 6% of the Earth's surface. Despite covering a relatively small area, these rainforests are home to a significant portion of the world's plant and animal species. The biodiversity found in tropical rainforests is unparalleled, making them vital for the health of our planet and the well-being of countless species.Response:

Plant growth in hot deserts is primarily restricted by the lack of organic matter and water scarcity. The extreme temperatures and arid conditions make it challenging for plants to thrive in these regions. Due to the limited availability of water and nutrients, plants in hot deserts have evolved unique adaptations to survive, such as deep root systems and water-storing tissues. This adaptation allows them to endure the harsh conditions prevalent in hot desert environments.

The soils in hot deserts are typically sandy, coarse, and low in nutrients due to the lack of organic matter. This lack of organic material contributes to the poor fertility of desert soils. As a result, the nutrient content in hot desert soils is limited, making it challenging for plants to obtain essential nutrients for growth and development. Despite these limitations, plant species in hot deserts have evolved mechanisms to thrive in such nutrient-poor conditions.
