Please hurry Need the answer John and Marianna are expecting their first baby. John has a widow's peak (dominant allele) hairline
while Marianna has a straight hairline (recessive allele). If they have a daughter, she will have a
widow's peak, not a hairline that is indeterminate or a mix between a widow's peak and a straight
line. Why is this so?

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
