I say consequences of the Black Death included a series of religious, social, and economic upheavals, which had profound effects on the course ofEuropean history. The Black Death was one of the most devastatingpandemics in human history, peaking in Europe between 1347 and 1350 with 30% to 65% of the population killed. It reduced world population from an estimated 450 million to between 350 and 375 million. It took 80 and in some areas more than 150 years for Europe's population to recover.f<span>rom the perspective of many of the survivors, however, the impact was much more benign, for their labor was in higher demand.

<span>An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. </span>

Explanation:
- Coral reefs are found in the oceans formed by the accumulation of the skeletal remains of the invertebrates. They are found under water.
- Cold seeps refers to those area where the gases such as methane, hydrogen sulfide comes out through the vent, under water.
- Hydrothermal vents are the places where the hot intruding magma reacts with the sea water producing a vent.
- Rocky intertidal zone refers to the zone between a high and a low tidal mark.
Thus under the ocean, the structures such as coral reefs, cold seeps and hydrothermal vents forms where the tide is not so high and not so low.
Kelp forest is the odd one, that refers to those brown colored seaweeds, having high nutrients in salt water.
