Summarize the three main reasons why energy is wasted at each trophic level. (use your own words)
Answers
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.

Which two structures produce energy that cells can
use?
O A and B
OB and C
O Cand D
O D and A
Answers
Answer:
According to the plant cell scheme, the two structures that produce energy that cells can use are D, which corresponds to mitochondria, and A, which is a chloroplast, so the answer is D and A (fourth option).
Explanation:
In the plant cell —unlike the animal cell— there are organelles called chloroplasts, responsible for converting light energy from the sun into chemical energy. In addition, there are mitochondria, which also provide useful energy to the cell.
In the chloroplast, photosynthesis takes place, a process that during the light phase produces ATP and NADPH⁺ from solar energy. In the mitochondria, energy in the form of ATP is obtained from glucose, due to oxidative phosphorylation and the electron transport chain.The organelles indicated in the diagram are mitochondria (A) and chloroplast (D), both responsible for producing energy for the plant cell.

Why are Acacia Trees dependent on Giraffes?
Answers
Answer:
One study found the growth of acacia trees depended on herbivores. When the trees were protected from herbivores, including the giraffe, they produced less nectar. It turns out they this nectar provided food for ants who defended them from pests like wood-boring beetles. Also Giraffe's eat the tree seeds and when they defecate the seeds fall into new places, growing more trees.

If a plant with chlorosis is unable to perform photosynthesis, what products (include
BOTH) are not being made?
Answers
Answer:
Glucose and oxygen
Explanation:
Photosynthesis is the process by which the cells of green plants synthesize their own food in the presence of sunlight. Although photosynthesis consists of various steps, it generally combines carbon dioxide (CO2) and water (H2O) to produce glucose (sugar) and oxygen gas (O2). The equation is as follows:
6CO2 (g) + 6H20 (l) → C6H12O6 (aq) + 6O2(g)
In a plant that possess chlorosis (a condition characterized by yellowing of leaves due to lack of chlorophyll), photosynthesis will not occur. This ultimately means that the photosynthetic products such as GLUCOSE AND OXYGEN WILL NOT BE MADE.

Why is DNA in the world?
Answers
Answer: Nine years ago I jumped at an opportunity to join the international team that was identifying the sequence of DNA bases, or “letters,” in the genome of the common chimpanzee (Pan troglodytes). As a biostatistician with a long-standing interest in human origins, I was eager to line up the human DNA sequence next to that of our closest living relative and take stock. A humbling truth emerged: our DNA blueprints are nearly 99 percent identical to theirs. That is, of the three billion letters that make up the human genome, only 15 million of them—less than 1 percent—have changed in the six million years or so since the human and chimp lineages diverged.
Evolutionary theory holds that the vast majority of these changes had little or no effect on our biology. But somewhere among those roughly 15 million bases lay the differences that made us human. I was determined to find them. Since then, I and others have made tantalizing progress in identifying a number of DNA sequences that set us apart from chimps.

Which of the following best explains why aerobic respiration is more energy efficient than anaerobic respiration?
Answers
With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
How can a shortage of nutrients harm organisms in an ecosystem? How can an excess of nutrients harm organisms in an ecosystem? Give an example of each scenario to support your answers.
Answers
Answer:
Explanation:
Shortage of nutrients in an ecosstem can harm an organism because when nutrients are scarse or very limited for organism and did not meet up with the organism requirements, there will be reduced metabolism and this can cause malfunction. Shortage of nutrients can lead to decline in growth and can lead to spring up of some diseases in the organism because enough nutrients us not available for good metabolic processes and fight diseases.
For example when an organism is deficient in vitamins and carbohydrates, the organism will not have energy to power metabolic processes and for it's activities and vitamins deficient will make the organism not to have the ability to fight against disease.
Too much of nutrients also affect organisms negatively. When there is much build up of nutrients, it can be harmful to the organisms and restrict metabolic processes.
For example too much of nutriwnts like too much of fat can block blood artieries and veins and thus can lead to inability of blood to flow .
