What would happen if algae, cyanobacteria, and plants were wiped out?

The algae, plants and cyanobacteria are the examples of producers.

The producers are the organisms, which makes food from the sunlight. In case, these producers are absent, the conversion of the light energy would not happen and the consumer would not be able to acquire energy. As a result, all the consumers and other organism would also be wiped out after some time.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

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.
