Explanation:

A keystone species is an organism that helps define an entire ecosystem. By keeping populations of mussels and barnacles in check, this sea star helps ensure healthy populations of seaweeds and the communities that feed on them—sea urchins, sea snails, limpets, and bivalves.

Bacteria in the phylum ________ occur as elementary or reticulate bodies depending on their life cycle stage, are obligate intra
HACTEHA [7]

Answer:

This question lacks options, options are:

Chlamydiae

Planctomycetes

Rickettsia

Bacteroidetes

The correct answer is Chlamydiae.

Explanation:

Chlamydiae together with mycoplasmas, constitute the bacterial species with the smallest genomes, possibly because they are obligate small intracellular parasites for a long time, which has allowed them to lose certain metabolic pathways, however, they contain DNA, RNA and ribosomes therefore synthesize their own proteins and nucleic acids. Chlamydiae have a unique biphasic life cycle: the elemental body, which is the infectious form, and the reticular body, which is the replicative and metabolically active form that possesses a fragile membrane that lacks the extensive disulfide bonds characteristic of elemental bodies. The characteristics of its biological cycle do not facilitate the possibility of exchange and acquisition of exogenous genetic material.

Wild salmon can be taken as one of the chief sources of food that provides energy. This form of energy may lead to renewable energy because it is endless, as the reproduction rate of wild salmon is fast with  large clutch size.  

Therefore, the wild salmon has the capability of reproducing quickly, which makes wild salmon a renewable resource.

What is the starfish experiment?​
vitfil [10]

Answer:

When starfish were removed from their environment, the species richness of that area went down. This was because the starfish ate the mussels, and when the starfish were removed, the mussels became abundant and preyed on many of the other species.

This experiment showed that the starfish were a keystone species. A keystone species is a species that has a low biomass but a large impact on the community they are living in.
