How do corals act as environmental indicators?
Coral reefs protect coastlines from ocean storms and floods. Coral reefs are environmental indicators of water quality because they can only tolerate narrow ranges of temperature, salinity, water clarity, and other water conditions.
How is climate change most significantly affecting coral reefs and sea life?
How is global warming most significantly affecting coral reefs and sea life? Increased concentrations of carbon dioxide are being absorbed by the oceans. This acidifies the oceans. … Methane traps more heat than carbon dioxide.
How has climate change affect biodiversity on the Great Barrier reef?
As water temperatures rise, many marine species are being forced to move south to cooler habitats. This shift creates increased competition for food and shelter in cooler waters, threatening the entire ecosystem.
How can we protect our coral reefs from climate change?
These emissions contribute to ocean acidification and increased ocean temperature. More acidic ocean waters impede coral growth and warmer waters cause coral bleaching. Reduce stormwater runoff. Reducing stormwater runoff can help prevent water pollution, reduce flooding, and protect our water resources.
What is an indicator species in an ecosystem?
indicator species, organism—often a microorganism or a plant—that serves as a measure of the environmental conditions that exist in a given locale. For example, greasewood indicates saline soil; mosses often indicate acid soil. Tubifex worms indicate oxygen-poor and stagnant water unfit to drink.
