In early spring, many wildflowers begin to grow, produce flowers, and release seeds. The leaves of the wildflowers make food before the leaves of the trees in the area begin to develop. The early growth pattern of the wildflowers would likely result in decreased competition for sunlight between the trees and the wildflowers (1). There is a good reason why the wildflowers grow so much earlier than the trees. If they start growing at the same time in spring, then the tree leaves will block out the sun for the wildflowers.
The - Crossopterygians - are ancestral to amphibians.
B. Reducing the amount of carbon dioxide in the atmosphere, as it exchanges with the ocean and is making it more acidic. Non-native species could become invasive, algae is generally not reabsorbed by the corals after bleaching, and calcium carbonate, although necessary for corals, would not reduce bleaching and could potentially contribute to it.
