Climate change is causing the average annual temperature to increase. birds that have adapted to temperatures in their environment must find a way to adapt. if temperatures warm up due to human activities, which adaptation are the birds most likely to make? a) lay fewer eggs. b) stop eating seeds. c) build smaller nests. d) move to cooler places.

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
