In a food web, each ____________ depends on the trophic level below it for energyA) Consumer
B) Decomposer
C) Detritivore
D) Producer

Answers

Answer:

The correct answer would be A) consumers.

Consumers are the organisms which depend on other organisms for their energy needs.

In a food chain, the consumer consumes other organisms present on lower trophic level.

For example, cow, deer, et cetera (herbivore) are the primary consumers which consume autotrophs or green plants which are present on lowest trophic level.

Similarly, lion, tiger, et cetera are the highest consumers which feed on organisms present on lower trophic levels such as cow, deer, giraffe et cetera.
A) Consumer

The consumer relies on the trophic level below it for energy to survive.

The five-kingdom system of classification reflects the idea that all organisms can be separated into two main groups: prokaryotes and eukaryotes. The new six-kingdom system recognizes three broader groups that include six kingdoms. How do the three basic groups of the six-kingdom system differ from those of the 5-kingdom system? A) The six-kingdom system has three domains in order to includes a new kingdom for viruses. B) The six-kingdom recognizes the vast differences in protists and divides them into two kingdoms. C) The six-kingdom system has three domains: two domains separate all prokaryotic organisms into two new groups. D) The six-kingdom system adds a broader classification of domain to divide all living things into three groups: microorganisms, plants, and animals.

Answers

Answer;

C. The six-kingdom system has three domains: two domains separate all prokaryotic organisms into two new groups.

Explanation;

  • The six-kingdom system has three domains: two domains separate all prokaryotic organisms into two new groups.
  • Organisms are classified into three Domains and into one of six Kingdoms of life. The three-domain system has Archaea, Bacteria, and Eukarya, while the Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.
  • All eukaryotic organisms are in the domain Eukarya. Prokaryotes are divided into two kingdoms and two domains, Archaea and Bacteria.
i believe the answer is c because there are 3 domains: Archaea, Bacteria, and eukraya. 

Explain what has to happen to join two monosaccharide units into a disaccharide.

Answers

Dehydration synthesis is the process by which two monosaccharide are joined to form a disaccharide.

Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.

Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose  (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.

Why is heritability important for both natural and artificial selection?

Answers

heritability is the relationship between nature and nurture, so essentially it is how the animal adapts to it's environment. It is important because if an animal was not able to adapt to it's environment it would end up becoming less common. Hope this helped.
