How Do Human Activities Cause Imbalance

1. Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and kill fish. biogeochemical cycles are the pathway that chemicals cycle within the ecosystems involving both living and non-living things. Human activities have a direct impact and can cause an imbalance of these chemicals. A few examples of this would be mining and burning fossil fuels, this would increase the amount of chemical elements removed from the reservoirs and cycling within the ecosystems. The excess chemical in the ecosystem would alter the species composition and diversity of the biotic community. Human activities can also alter the transfer rate. For example if humans mine phosphate ores and use
Compare and contrast the traits and growth patterns of opportunistic verse equilibrium population. Provide one example for each. Opportunistic species tend to exhibit exponential growth. They are small in size, mature early, have short life span, and provide limited parental care even though having a great number of off-spring. Density-independent factors tend to regulate the population size,which is large enough to survive an event threatens to eliminate it. These populations typically have a high dispersal captivity. Two examples of opportunistic are insects and weeds. On the other hand
Equilibrium species exhibit logistic growth, with the population size remaining small. Resources are scarce, and individuals compete for them. Those with phenotypes best suited to the environment survive and tend to have the most offspring. They nurture their off spring and are an active part of their survival and development. Therefore they are fairly large, are slow to mature, and have a fairly long life span. The growth of equilibrium species are regulated by density-dependent factors. Birds and mammals are good examples of equilibrium species. As you can see Opportunistic species and Equilibrium species are very different the only thing they have in common is that both life history patterns can lead to
