I’m trying to do a lab report and answer the following questions • Why do you see increase and decrease in the invasive species population? • What are the implications associated with these alterations to the ecosystem as a whole? I have filled in the data but need help with answering a Plagiarism free answering questions using the following: Purpose – Introduction: Hypothesis/Predicted Outcome Methods Results/Outcome Discussion/Analysis Years Zebra and Quagga Mussel (density/m2) Phytoplankton (µg/ml) Zooplankton (µg/ml) Cladophora Biomass (g/m2) Foraging Fish (kilotons) Lake Trout (kilotons) 0 100 3 2 10 150 15 4 1000 2.5 1 100 100 10 7 2500 2 .5 200 80 8 10 7500 1.5 .25 600 50 5 13 15000 1 .1 700 25 2.5 16 7500 1.5 .2 243 40 4 20 5000 1.75 .4 136 60 6Explanation / Answer
Introduction:-An increase and decrease is always seen in invasive species population because due to increasing threat to the species the population decreases(such as due to hunting,pollution,other hazards like tsunami,volcanoes etc)and at the same due to migration and other activities of species,an increase in species population is seen.
Analysis:-The population of certain species is taken and examined.
In case of Zebra and Quagga Mussel,the species rate decreased and now a days zebra is also being treated as a rare species which must be protected.
In case of Phytoplankton,the decrease in species rate is due to the fishes. These phytoplanktons mainly grow under water and the fishes living there mainly feed on these phytoplanktons.
In case of zooplanktons,these are also similar to phytoplanktons and their rate of growth is similar to phytoplanktons.
In case of Cladophora biomass,there is an increase in this type due to the production of electricity using biomass. Electricity prepared from biomass is pure and there is an increase in this type.
Foraging fishes breed and an increase is observed due to the process of feeding and breeding in order to produce new species but sometimes these are being eaten by other big fishes under the sea.
Lake trout as in case of other small organisms are found in river and lake areas and are being eaten by fishes living in those areas.
