Why is there constant competition for limited resources in each generation?

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
