use evidence from the simulation to support the claim that a decrease in light levels at latitudes greater than 30° will lead to a decrease in coral diversity, and explain why this will lead to a decrease in biodiversity of the other species in the coral reef ecosystem. enter your answer in the box provided.
Answer
Brief Explanations:
Corals rely on photosynthesis - symbiotic algae in corals need light. At latitudes greater than 30°, less light means less photosynthesis, harming coral health and diversity. Corals are foundation species in reef ecosystems. A decline in coral diversity reduces habitat complexity and food sources for other species, thus decreasing overall biodiversity in the reef ecosystem. Evidence from the simulation could include data on coral species numbers and light - level changes at these latitudes, showing a negative correlation.
Answer:
A decrease in light levels at latitudes greater than 30° reduces coral diversity as corals depend on light for the photosynthesis of their symbiotic algae. Since corals are key species in reef ecosystems, a decline in their diversity leads to a decrease in the biodiversity of other species by reducing habitat and food availability. Evidence from the simulation may show a negative relationship between light levels and coral species numbers at these latitudes.
