degradation thresholds shape tropical biodiversity Biology Diagrams Deforestation: Disrupting Terrestrial Trophic Levels. Deforestation, the widespread clearing of forests for various purposes, is one of the most significant threats to terrestrial ecosystems. This practice disrupts trophic levels by destroying habitats and reducing the availability of primary producers, which are essential for the survival of 6. Explain the role of decomposers in ecosystems. Answer: Decomposers, including fungi, bacteria, and certain invertebrates, break down dead organisms and organic waste, recycling nutrients back into the soil. They occupy the final trophic level and play an essential role in nutrient cycling. By decomposing dead material, they return vital nutrients like nitrogen, carbon, and phosphorus to the
With deforestation, the source of primary production shifts from primarily kelps to ephemeral microalgae, macroalgae, and phytoplankton. (1991)], although there has been little attempt to study species-level trophic interactions beyond simple two-species predator-prey linkages [for example, see Schmitt (1982) and Sala and Graham (2002 The pace of deforestation in tropical forests has achieved unprecedented rates, requiring effective and achievable conservation mitigations that are also easily understood by society and policy makers. may worsen and impact different trophic levels - causing an ecological meltdown and collapse in ecosystem functionality.

Deforestation is a complex and pressing issue that requires urgent and comprehensive action. While the causes of deforestation are deeply rooted in economic, political, and social factors, the consequences are far-reaching and impact not just the environment but also communities and economies worldwide. MCQs on "Trophic Levels in
Saikh, H., Varadachari, C. & Ghosh, K. Changes in carbon, nitrogen and phosphorus levels due to deforestation and cultivation: a case study in Simlipal National Park, India. Plant Soil 198 , 137 Human activities are, however, causing secondary extinctions at greater levels than expected from random species losses (Dunne et al. 2002). Networks are less robust to the loss of highly connected species because the more trophic links that a species has to other species in a food web, the more potential it has to affect community structure.
