AQA Science Exam Question and Answer
Question:
Discuss the characteristics and components of terrestrial ecosystems. Explain the interactions between biotic and abiotic factors within terrestrial environments and their influence on ecosystem dynamics. Provide an example of a specific terrestrial ecosystem and describe how its unique features contribute to the diversity of life found within it.
Answer:
Terrestrial ecosystems are land-based habitats that support a wide array of plant and animal life. They encompass various environments, including forests, grasslands, deserts, and tundras. Terrestrial ecosystems are characterised by their unique components, such as soil, air, water, and living organisms.
The interactions between biotic (living) and abiotic (non-living) factors are essential for sustaining terrestrial ecosystems. Biotic factors, including plants, animals, and microorganisms, interact with abiotic factors like temperature, precipitation, and soil composition. These interactions influence nutrient cycles, energy flow, and the overall balance of the ecosystem.
A specific example is the tropical rainforest, a highly diverse terrestrial ecosystem. The rainforest's abundant rainfall, consistent temperature, and nutrient-rich soils support a complex web of life. Biotic interactions range from predator-prey relationships to symbiotic partnerships, like those between certain tree species and ants that provide protection.
The rainforest's immense biodiversity is a direct result of its unique features and intricate interactions. The dense vegetation provides various niches for animals and plants to thrive. Moreover, the complex relationships between species contribute to the ecosystem's resilience and stability.
