Summary Introduction
Introduction: The ecosystem present in a water body is known as aquatic ecosystem. It is of two types, namely marine ecosystem, and fresh water ecosystems. There are three main ecological categories of organisms present in both fresh water and marine ecosystems. These are plankton, nekton, and benthos.

With respect to planktonic communities in the ocean, which ONE of the following statements is correct?
a.
Population numbers of plankton species vary over time, but in particular places are consistent
b.
Population numbers of plankton species are consistent over time, but vary from place to place
c.
The diversity of planktonic communities is constantly changing, and dominance by any one group is always correlated with one or more environmental factors
d.

Thinking Analytically
Considering the fact that we have already found more than 20,000 deep-sea marine species and we have only explored a few percent of the deep ocean, how many total species do you think there may be in the deep sea?

- The resource page discusses an increasing threat of nuisance flooding in North Carolina. To understand what nuisance flooding is, you have to have a basic understanding of tides. How are tides generated and propagated around ocean basins? Explain how the factors that control tides change over the course of one month and tie that back to the problems with nuisance flooding. Please be sure to reference your article (include information about it) in your answer and define any scientific terms your audience may not know.arrow_forwardThe next couple of lectures will deal with organisms that live on the sea floor.

- 85. An ecologist collects three related beetle species – one from a tropical rain forest, another from a desert and the third from the tundra. Back in the lab, she places all the beetles in a warm, dry environmental chamber and measures water loss across the cuticle. From highest to lowest rate of water loss, how would you expect the three species to rank?a. tropical rain forest > desert > tundrab. desert > tundra > tropical rain forestc. tundra > desert > tropical rain forestd. desert > tropical rain forest > tundrae. tropical rain forest > tundra > desertarrow_forwardYou have two identical bags and fill them with the same amount and type of leaves. You put the identical bags in two different areas of a river. After several weeks, one set of leaves has almost disappeared and the bag is full of organisms. The other set of leaves is still mostly whole and the bag has few organisms in it. Questions: What are some ways the two different areas of the river could be different? How might these differences explain why the leaf packs in one area have more organisms than the leaf packs in another area?arrow_forwardLionfish are native to the Indo-Pacific, which includes some of the most biodiverse marine areas on Earth. In the video about lionfish in the Atlantic, however, you learned that lionfish have devastating effects on the biodiversity found on coral reefs in the Atlantic.

How do insects in the a) tropics, b) cold regions of the world and c) desert cope with the climatic condition? Elaborate and give examplesarrow_forwardThe pelagic zone of the ocean is the area of the ocean that is neither close to the bottom nor close to land. There are a wide variety of organisms that inhabit the pelagic zone. Phytoplankton float along the surface, using photosynthesis to produce food. Zooplankton are tiny organisms that float in the surface waters and feed on the abundant phytoplankton. Krill, small crustaceans, also feed on phytoplankton. They display vertical migration in which they swim at deeper depths during the day and then come up to the surface waters at night to eat. What is the relationship between zooplankton and krill? a) Symbiosis b) Competition c) Parasitism d) Commensalism e) Mutualismarrow_forwardThe concept of surface area to volume ratio can be applied to multicellular organisms.
