The image shows an energy pyramid. Vulture Coyote Prairie dog Grass Which statement about how energy flows through this ecosystem is supported by this ecological pyramid? OA. The highest trophic level has the most available energy because vultures are a tertiary consumer. B. The organisms of the second trophic level obtain their energy from the coyotes located in the third trophic level. C. The grasses' trophic level has the most energy, but only some of that energy moves to the second trophic level. D. The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.

Answers

The third trophic level is made up of prairie dogs that get their matter and energy from the grasses (option d).

The energy pyramid depicted in the image illustrates the flow of energy through an ecosystem. In an energy pyramid, each level represents a trophic level, indicating the position of organisms in a food chain. The pyramid narrows as it ascends, indicating the decrease in available energy at higher trophic levels.

In this specific pyramid, the lowest trophic level is occupied by the grass. This makes sense because grass is a producer that captures energy from the sun through photosynthesis. As a result, it possesses the most energy within the ecosystem.

Moving up the pyramid, the second trophic level is occupied by the prairie dogs. They are herbivores that primarily consume grass for their energy needs. This demonstrates that the prairie dogs acquire their matter and energy from the grasses, supporting option D.

The third trophic level contains the coyotes, which are tertiary consumers. Tertiary consumers feed on other consumers, not producers. Therefore, option A is incorrect since vultures, not coyotes, are tertiary consumers in this ecosystem.

Option B is also incorrect because the coyotes do not obtain their energy from other coyotes located in the third trophic level. They acquire their energy indirectly from the grasses through the prairie dogs.

Finally, option C is incorrect as it states that the grasses' trophic level has the most energy. While the grasses are indeed the primary producers and possess the most energy, not all of that energy moves to the second trophic level.

Thus, the correct statement supported by the ecological pyramid is option D: The third trophic level is made up of prairie dogs that get their matter and energy from the grasses.

c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over

Answers

Answer:

The correct answer would be -

1- YR, Yr, yR and yr.

2. Yr, yR

3. YR, yr

4. YR, Yr, yR & yr

Explanation:

A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.

The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.

1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.

2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.

3).  if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.

4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.

Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration until membrane is achieved.

What is osmosis?Osmosis is the naturally occurring net movement or diffusion of solvent molecules across a selectively permeable membrane from a region of high water potential to a region of low water potential in a manner that tends to balance the solute concentrations on the two sides.The spontaneous movement of water or other solvents through a semipermeable membrane is known as osmosis.Transport of solute molecules over a semipermeable membrane from a lower concentration of solution to a higher concentration.Osmosis lets an animal cell absorb water from the intestines into the blood. Here are some further instances of osmosis. Osmosis is responsible for the soil's ability to absorb water. In contrast to the soil, the concentration is higher in the plant roots.Water enters the roots as a result.Osmosis is the movement of a solvent toward a more concentrated solute across a semipermeable membrane.

describe the effect on chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light?

Answers

When chlorophyll-containing photosystems absorb photons of light, the energy from the light is transferred to the chlorophyll molecules. This energy excites the electrons in the chlorophyll, causing them to move to a higher energy level.

This process is called photoexcitation. The excited electrons are then passed through a series of electron transport chains or photosynthetic pigments, eventually leading to the production of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are used as energy carriers in the process of photosynthesis.

What is the Chlorophyll  about?

The overall effect of the above process is the conversion of light energy into chemical energy, which is then used by plants to produce glucose (a sugar) from carbon dioxide and water. This process is known as the light-dependent reactions of photosynthesis.

Therefore, Chlorophyll also plays another role in photosynthesis, it helps to protect the plant from excess light. When the light is too intense, the chlorophyll molecules can become over-excited, which can lead to the formation of reactive oxygen species (ROS) that can damage the plant cells.
