#7 A cuckoo bird lays its eggs in a warbler bird's nest. Once hatched, the cuckoo chicks displace the warbler chicks, tricking the parent warbler into caring for them over their own young. What type of ecological interaction does the cuckoo have with the warbler? a. Commensalism

b. Competition

c. Mutualism

d. Parasitism

Parasitism

Explanation:

Parasitism is a kind of interaction between organisms in which only one organism gains from the interaction. Usually one organism gains at the expense of the other organism.

In this case, the cuckoo bird gains at the expense of the warbler bird. The cuckoo bird lays its eggs in the warbler bird nest and also tricks the warbler bird to care for its young at the expense of the warbler bird's young.

This is parasitism.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
