An increase in the number of brown bears in an alaskan river ecosystem causes the ecosystem's carrying capacity for salmon to decrease. which two terms describe the brown bear in this scenario? a. parasite b. biotic factor c. limiting factor d. primary consumer

B and C, biotic factor and limiting factor

Explanation:

The carrying capacity of an ecosystem is the maximum number of organisms that an ecosystem can support based on the resources it contains.

The more the resources an ecosystem has, the more the number of organisms it can sustain and the higher the carrying capacity. On the other hand, the lower the resources an ecosystem has, the lower the number of organisms it can sustain and the lower the carrying capacity. These resources are often refers to as limiting factors.

Properly defined, limiting factors are those variables that act on a population and prevent it from increasing indefinitely. These variables can be density dependent or density independent.

Biotic factors are the living factors of the environment or an ecosystem that tend to interact with individuals living in such environment/ecosystem.

Hence, in this case, the brown bears can be viewed as a limiting factor since their increase in the river ecosystem decreased the ecosystem's carrying capacity for salmon. At the same time, they are part of the living components of the salmon's environment and can therefore be considered as a biotic factor.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
