Students know energy entering ecosystems as sunlight is transferred Commercial kelp harvesting is potentially the greatest threat to long-term kelp stability. Describe how changes in the abundance of one species can affect other species in a food web. habitats, (b) to generate an idealized giant kelp forest food web for the region, and (c) to determine changes in the diversity and complexity of this food web due to localized deforestation. A wide range of marine mammals inhabit kelp forests for protection and food. From the extractions of kelp during World War I for potash to the modern use of kelp for food additives and pharmaceutical products, kelp has proven to be a dynamic and highly demanded product.
