Wetlands are often drained in many regions to facilitate human use of the land. This happens a lot within the Pairie Provinces of Canada, where wetlands are drained to make way for agriculture. Wetlands are also often drained so as to use the land for building houses. Humans have also altered the flow of rivers through constructing dams and over-abstracting water. In many regions, depressions that would have been flooded in the past to form wetlands are no longer saturated. Wetlands also act as a 'sink' for many pollutants, and much of the pollution released into upstream rivers by humans may settle into the relatively stagnant waters of wetlands, to be absorbed into the sediments, where often it acts as a chronic pollutant, negatively effecting the aquatic ecosystem and water quality downstream.

Answer:
Virškinimas yra didelių netirpių maisto molekulių suskaidymas į mažas vandenyje tirpias maisto molekules, kad jas būtų galima absorbuoti į vandeningą kraujo plazmą. Tam tikruose organizmuose šios mažesnės medžiagos absorbuojamos per plonąją žarną į kraują.
Explanation:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Answer;
3. the two organisms belong to the same kingdom
Explanation;
-The classification of living things includes 7 levels, from the highest to lowest rank: kingdom, phylum, classes, order, families, genus, and species . The most basic classification of living things is kingdoms.
-The broadest classifications are by domain and kingdom; the most specific classification is by genus and species.
Therefore; if two organisms are in the same phylum, then it means they both belong to the same kingdom, because kingdom is the rank of classification higher than phylum.
