Question

kelp forest ecosystems off the coast of northern california declined drastically from 2013 to 2019. this occurred due to a number of factors, including a marine heat wave, an el niño event, and the emergence of sea star wasting disease, which decimated the population of sunflower stars, a major predator of sea urchins. many scientists and conservationists are working to restore kelp forest ecosystems in order to preserve the biodiversity and ecosystem services they provide. which strategies might help to restore kelp forest ecosystems in deforested areas? select all that apply. breeding healthy sunflower stars in captivity and releasing them in deforested areas developing more heat - tolerant varieties of kelp to plant in deforested areas removing sea urchins from deforested areas

Explanation:

Sunflower stars predate sea urchins which harm kelp. Re - introducing healthy sunflower stars can control sea urchin populations. Developing heat - tolerant kelp helps it survive in warmer conditions. Removing sea urchins directly reduces the threat to kelp.

Answer:

breeding healthy sunflower stars in captivity and releasing them in deforested areas, developing more heat - tolerant varieties of kelp to plant in deforested areas, removing sea urchins from deforested areas
