Question

the rise of wild hybrids
video reflection questions
what is one of the risks associated with wild hybrids, according to the video?
a) they may not be able to reproduce
b) they can disrupt the balance of ecosystems
c) they always become dominant species
d) they never survive in the wild
how does the video suggest wild hybrids impact biodiversity?
a) they help increase genetic diversity
b) they often result in the extinction of pure species
c) they do not affect biodiversity in any way
d) they only affect plant biodiversity, not animal biodiversity
what role does human activity play in the rise of wild hybrids?
a) humans are breeding wild hybrids for conservation purposes
b) human activity is accelerating hybridization due to habitat encroachment
c) humans are trying to eliminate hybrids from the wild
d) humans have no role in hybridization at all

Explanation:

1. For the first question: Wild hybrids can outcompete native species, alter food webs, and break down established ecosystem balances. Option A is a common hybrid trait but not the primary ecosystem risk here, C is incorrect as they do not always become dominant, D is false as wild hybrids do survive in the wild.
2. For the second question: While hybrids can introduce new genetic combinations, a major documented impact is that they can breed with pure species, diluting their gene pools and driving pure species to extinction over time. A is a minor positive, C and D are factually incorrect.
3. For the third question: Human habitat destruction and encroachment forces different species into shared, smaller habitats, increasing the likelihood of interspecies mating and hybridization. A, C, and D do not align with standard ecological observations of human impacts on wild hybridization.

Answer:

1. B) They can disrupt the balance of ecosystems
2. B) They often result in the extinction of pure species
3. B) Human activity is accelerating hybridization due to habitat encroachment
