Local economies receive billions of dollars from visitors to reefs through diving tours, recreational fishing trips, hotels, restaurants, and other businesses based near reef ecosystems. Coral reef structures also buffer shorelines against 97 percent of the energy from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion.

It describes how energy flows from producers to herbivores (primary consumers) and then to carnivores (secondary and tertiary consumers) in food chains and webs. The text highlights the inefficiency of energy transfer, averaging around 10%, leading to a decrease in energy and biomass at higher trophic levels. This creates pyramids illustrating the balance in ecosystems.

It covers key topics like biodiversity, population dynamics, ecosystem processes (energy flow, nutrient cycling), food chains, biomes, and biogeochemical cycles. Additionally, it addresses pollution and species interactions, including symbiosis and pest control methods.
