The correct answer is C. A decrease in the population of sea ducks
Explanation:
Food webs are diagrams that represent the relationship of organisms in an ecosystem by showing feeding or predatory relationships. This means food webs show which organisms eats another organism. In the case of the food web presented, this shows bald eagles fed on sea ducks and large piscivorous fish, this implies for survival bald eagles need from these two organisms. In this context, a decrease in the population of sea ducks (option C) would cause a decrease in the population of eagles because fewer sea ducks imply less food for eagles, and therefore fewer resources to survive.
Answer:
Gene flow
Explanation:
Evolution is the changes seen in the growth, development, features of a certain group of species during the cause of time. Evolution causes changes in the gene frequency of species from one generation to the next generation.
There are 5 important mechanisms of evolution and they are: Gene flow, mutation, genetic drift, natural selection and non random mating.
Gene flow as a mechanism of evolution is the exchange or transfer of genes between a group of species as they move from one place to another. Gene flow can either increase the rate of evolution or decrease it.
The difference between butterflies and moths is a lot like the difference between frogs and toads. There are some rules of thumb you can follow to tell them apart, but there are also exceptions to those rules. Next, we'll look at exactly what makes a butterfly different from the moth and what clubs and feathers have to do with it.
