Worked Solution & Example Answer:Using Figure 7, identify a producer - AQA - GCSE Geography - Question 2 - 2023 - Paper 1
Step 1
Step 2
What is the difference between a food chain and a food web?
Answer
A food chain represents a linear sequence of energy transfer within an ecosystem, showing how one organism eats another. In contrast, a food web illustrates a more complex network of interconnected food chains, depicting how multiple organisms interact and rely on one another within a habitat.
Step 3
Using Figure 7, state one effect on the food web if disease killed most of the trout.
Answer
If disease killed most of the trout, one effect on the food web would be an increase in the population of organisms that trout typically prey upon, potentially leading to an imbalance in the ecosystem.
Step 4
For a small-scale ecosystem that you have studied, outline the link between producers and consumers.
Answer
In a small-scale ecosystem, such as a garden, producers like vegetables provide energy and nutrients through photosynthesis. Consumers, such as insects and herbivores, depend on these producers for sustenance, illustrating the vital link in energy transfer between these two groups.
Step 5
Using Figure 8, describe the distribution of tropical rainforests.
Answer
Tropical rainforests are predominantly found near the equator, characterized by high humidity and abundant rainfall. Their distribution typically follows latitudinal lines, with significant coverage in regions such as the Amazon Basin, Congo Basin, and Southeast Asia.
Step 6
Step 7
Outline one reason why nutrient cycling is very rapid in tropical rainforests.
Answer
Nutrient cycling is very rapid in tropical rainforests due to the high rate of decomposition facilitated by warm temperatures and abundant moisture, which accelerates the breakdown of organic matter and recycling of nutrients.
Step 8
'Tropical rainforest deforestation has major economic and environmental impacts.' Do you agree? Use Figure 10 and your own understanding to explain your answer.
Answer
Yes, I agree. Deforestation leads to loss of biodiversity, disrupting ecosystems and threatening species survival. Economically, it can create short-term gains through logging or agriculture, but long-term consequences include soil degradation and loss of ecosystem services, such as carbon storage and water regulation.
Step 9
Choose either a hot desert environment or a cold environment. Discuss the opportunities for economic development in your chosen environment. Use a case study and your own understanding.
Answer
In a hot desert environment, economic opportunities include solar energy production due to high sunlight exposure. For instance, the Mojave Desert in California has become a hotspot for solar farms, capitalizing on the region's climate to produce renewable energy, creating jobs, and fostering technological advancements in sustainable practices.
