Question

since 2013, the population of sea stars along north americas pacific coast has been dramatically reduced. microbiologist ian hewson believes a type of virus known as sea star associated densovirus (ssadv) is responsible. due to the disease, sea stars eventually decompose into a white sludge. surprisingly, though, hundreds of sea star babies appeared in the spring of 2016 along the oregon coast. researchers think that the massive reduction in adult sea stars has contributed to the baby boom. fewer hungry adult sea stars means more food for hungry babies. in turn, more food has led to a greater survival rate for the youngsters. match causes with their effects. sea stars are getting ssadv. more food is available. cause effect sea stars are disintegrating into white goo. more sea star babies are surviving.

Explanation:

The virus SSAaDV causes sea stars to decompose into white sludge. The reduction in adult sea stars due to the virus leads to more food available for baby sea stars, resulting in more baby sea stars surviving.

Answer:

Cause: Sea stars are getting SSAaDV. Effect: Sea stars are disintegrating into white goo.
Cause: More food is available. Effect: More sea star babies are surviving.
