What are the differences between the source of energy of producers and consumer
Answer:
Producers are capable of photosynthesis, a process by which they covert light energy into chemical energy, while consumers use respiration. Producers generate complex organic molecules, while consumers break them down into simpler ones (say, sugars to carbon dioxide, etc.).

What could create the need for a secondary succession?
i need the answer
Answer:
Particularly common types of secondary succession include responses to natural disturbances such as fire, flood, and severe winds, and to human-caused disturbances such as logging and agriculture. In secondary succession, the soils and organisms need to be left unharmed so there is a way for the new material to rebuild.

Which behavior is both territorial and used for courtship?
1.) baring teeth as a sign of aggression 2.) sparring or wrestling using antlers or horns
3.) dance rituals with potential partners
4.)defending a nest from predators
Answer:
2.) sparring or wrestling using antlers or horns
Explanation:
Territorial behavior is defined as the animal behavior in which animals protect their territory from other species.
Courtship behavior is defined as the animal behavior that is involved in mating and eventual reproduction.
Sparring or wrestling using antlers or horns is both territorial and used for courtship. Many animals or males uses their antlers or horns for wrestling or to fight with other animals to protect their territory while some males are involved in ritualized mating behaviors that include antler wrestling (sparring). The loud vocalizations during antler wrestling show the dominance of males that females and leads to mating.
Hence, the correct answer is "2.) sparring or wrestling using antlers or horns".

While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nucleic acid with a ladder structure and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, what conclusion can the scientist draw regarding this nucleic acid?
Answer:
Based on the information , the scientist concluded that the regarding nucleic acid is DNA (Deoxyribonucleic Acid) .The structure of DNA is attached below -:
Explanation:
PROPERTIES OF DNA -
In humans and almost all other species, DNA, or deoxyribonucleic acid, is an inherited substance. Almost every cell in the body of an individual has the same DNA. The DNA information is stored as a code consisting of four chemical bases: adenine (A), cytosine ( C), guanine ( G) and thymine ( T). In order to form units called base pairs, DNA bases pair up with each other, A with T and C with G. A sugar molecule and a phosphate molecule are both affixed to each base. Together, a nucleotide is called a base, sugar , and phosphate. Two long strands are arranged with nucleotides that form a spiral called a double helix. The double helix structure is much like a ladder, with the base pairs forming the rungs of the ladder and the molecules of sugar and phosphate forming the vertical sidepieces of the ladder.An significant DNA property is that it can duplicate itself or create copies of it. In the double helix, each strand of DNA will serve as a template for duplicating the sequence of bases. As each new cell requires to have an exact copy of the DNA present in the old cell, this is important as cells divide.Hence, the structure identified and conclude by the scientist is DNA (deoxyribonucleic acid). Thus, the structure of DNA is attached below.
Answer:
✓ The nucleic acid is DNA and would be found in the cell's nucleus

Give the symbols for the element that makes up each of the following:
______Carbohydrates.______ Lipids. _____DNA. _____Proteins.
Answer:
The correct answer is :
1. CHO
2. CHO
3. CHONP
4. CHON
Explanation:
Carbohydrates are composed of the carbon, hydrogen, oxygen in the ration of 1:2:1 which means hydrogen atoms are double than oxygen and carbon atoms. Carbohydrates are also known as sugars or polymer of sugars.
Lipids are composed of long chains of fatty acids made up of carbon, hydrogen, and oxygen molecules that are insoluble however ade up of organic molecules.
DNA or deoxyribose nucleic acid is the basic unit of cell and known as genetic material. It is made up of ribose sugar, a nitrogenous base, and phosphate backbone so elements that make these nutrients are Carbon, hydrogen, and oxygen with nitrogen and phosphorus.
Proteins are made up of amino acids that have carbon, hydrogen, oxygen, and nitrogen element in them.
The 4 macromolecules are namely Carbohydrates, Proteins, Nucleic acids, and Lipids. The composition of each macromolecule is defined by the elements present.
The symbols for the element that makes up each macromolecule are listed below:
Carbohydrates-H, C, and O(Hydrogen, Carbon, and Oxygen) Lipids-H, C, and O(Hydrogen, Carbon, and Oxygen) DNA-O, H, N, C, and P(Oxygen, Hydrogen, Nitrogen, Carbon, and Phosphorus) Proteins-O, H, C, and N(Oxygen, Hydrogen, Carbon, and Nitrogen)Thus, the symbols of the element that make up Carbohydrates, Proteins, Nucleic acids, and Lipids are defined.
