Using Figure 7, identify a producer - AQA - GCSE Geography - Question 2 - 2023 - Paper 1

A food chain is a linear representation showing how energy flows through different organisms, where each level represents a step in the energy transfer. In contrast, a food web is a more complex network of interconnected food chains that illustrates the various feeding relationships in an ecosystem.

If disease killed most of the trout, one effect on the food web would be an increase in the population of the organisms that trout typically prey on, leading to potential imbalances in the ecosystem.

In a small-scale ecosystem, producers such as plants convert sunlight into energy, forming the base of the food web. Consumers, like herbivores that feed on these plants, derive their energy from them. This interaction portrays a direct link where energy is transferred from producers to consumers, sustaining the ecosystem.

Tropical rainforests are predominantly located near the equator, characterized by high levels of rainfall and warm temperatures. They exhibit a diverse array of flora and fauna, showcasing a dense canopy and rich biodiversity.

The correct percentage stored in the roots, as illustrated in Figure 9, is B 12.5%.

Nutrient cycling is very rapid in tropical rainforests due to the high temperatures and moisture levels, which accelerate decomposition and facilitate quick nutrient uptake by plants.

I agree that tropical rainforest deforestation has significant economic and environmental impacts. Economically, deforestation can lead to short-term gains through logging and land conversion; however, it often results in long-term losses as biodiversity is lost, and environmental services are degraded. Environmental impacts include loss of habitat, reduction in carbon storage, and disruption of water cycles, all of which are critical for maintaining ecological balance.

In a hot desert environment, economic opportunities include tourism, solar energy, and mining. A case study of the Nevada desert shows significant investment in solar power due to the abundant sunlight, which can provide clean energy and jobs. Additionally, tourism thrives by capitalizing on unique landscapes and activities, promoting local economies while also raising awareness about environmental conservation.
