Which of the following is an r-selected species in the ocean and why? a. algae are an r-selected species because they have a very slow growth phase. b. algae are an r-selected species because they have a very rapid growth phase. c. birds are an r-selected species because they have long life spans. d. birds are an r-selected species because they have short life spans. will give brainliesttt

B. Algae are an r-selected species because they have a very rapid growth phase.

Reasoning: r-selected species are those that emphasize high growth rates.

The correct answer is option B, that is, algae are an r-selected species because they have a very rapid growth phase.

The species that show high growth rates, usually exploit less-crowded ecological niches and generate many offspring, each of which exhibiting a comparatively low possibility of surviving to adulthood are known as r-selected species.  

One of the illustrating features of r-selected species is the production of numerous small offspring succeeded by exponential population growth. They mature quickly and require short gestation periods, and exhibits short life spans.  

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

the temperature of the gas, in k, not celsius.
