45. In western Sweden, coastal marine ecosystems have been exposed to discharge of
nutrients over several decades. As a result, algal blooms are more common.Algal mats on the
sea bottom limit sunlight and alter the amount of dissolved oxygen in the water. Additionally,
some algae produce toxic compounds that can enter shellfish. Furthermore, the decomposing
algae produces a strong odor. Which statements below correctly match the outcomes to their
effects on value of the ecosystem? Check all that apply.

of high discharge. These ecosystems can be very rich in both quantity and diversity of
organisms and can contain up to 1,000 times more species than a river. Many floodplains have
been compromised by the construction of levees, pollution, and the draining of wetlands and
marshes. A restoration project that focuses its efforts on the removal of levees and the

to correlate health and breeding success to levels of 13C in their blood (a chemical signature
indicating the source of their diet). Birds with lower levels of 13C in their blood return to their
spring breeding ground sooner, weigh more and produce more offspring. Based on this, what
