nonliving and biotic

Explanation:

A decaying tree is the one that is undergoing decomposition by microbes. Since the decaying tree does not exhibit any of the life processes (respiration, nutrition, metabolism, reproduction etc.), it is non-living thing. The decaying organic matter is the part of biotic components of ecosystem. Abiotic factors of an ecosystem include physical and climatic factors only.

b. nonliving and biotic

Explanation:

for anyone on edge. 2020

you click your profile picture in the top right corner and it says edit profile.

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.
