Question

1. How aquatic and terrestrial life similar/different? What unique challenges exist in both? Discuss how either existence could be considered ecologically “better” or “worse”? Using real examples from lecture and the textbook support and illustrate your points.

Answer 1

ANS:DIFFERENCE:-

In Terrestrial life mainly found only on landforms,have low availability of water as compare to the aquatic ,greater temperature fluctuations, availability of light is greater and atmosphere is more transparent in land, availability of gases , have larger biodiversity but the main thing is that organism respire with the help of lungs.

In aquatic life mainly exists in water ,it is the largest ecosystem, have largest biodiversity low temperature variations as compare to the land different , it is more stable than terrestrial environments and organisms respire mainly through gills.

SIMLIARITY:-

In both kind of habitat organisms respire , perform the process of photosynthesis ,both of have large biodiversity, food chain existence in both habitat.

as we know that both life is the part of the ecosystem and here all the living or non living components interact with each other but the both cannot exist independent in better way because both life have their own but exchange of gases or energy depend upon on each other in terrestrial and aquatic life like terrestrial habit consists of particular kind of mixture of gases and have their own food chain and in same way organism live in aquatic have their own system .So that the nutrients, organism, water, air, and any other part of ecosystems can move in and out of ecosystem. Flow of materials into and out of ecosystems cross boundaries between ecosystems and connect them together. So we can say that existence of either life or ecosystem not establish properly it is not develop better way.

example :-

The interaction or dependence of both life have been in various ecosystems. The land -sea interface or coastal ecotone is a major ecosystem where a transition area between the body of water and the shoreline is found .It show how factors in two ecosystem interact and affect each other.

different atmospheric cycle like water, soil cycle depend on each other and maintain the balance of the environment.
