Label each organism in the food web as a producer, consumer, or decomposer. Hope u can help.
Hi, The center image is a decomposer because it decomposes the dead organisms. The grass is a producer since it produces its own energy through photosynthesis. The rest are consumers because they consume other organisms to get energy. Hope that helped!
The grass is the producer, the grasshopper, rabbit, two birds, and the wolf are the consumers, and the fungus in the middle is the decomposer, as it decomposes everything after death.
What is the significance of the producer and the consumer in the food web?In the food web, there are producers, like the green grass that is depicted here, that produce foods with the help of photosynthesis, which are later taken by consumers like the rabbit and the grasshopper. After the consumer and producer have died, all of these are decomposed by the fungi that are centrally present in order to maintain the nutrient cycle.
Hence, the grass is the producer, the grasshopper, rabbit, two birds, and the wolf are the consumers, and the fungus in the middle is the decomposer, as it decomposes everything after death.

Answer:
B) Random fluctuations in the gene frequencies within a population
Explanation:
Genetic drift is one of the evolutionary process that deviated the population from Hardy–Weinberg equilibrium. Genetic drift refers to the change in the allele frequency of population due to chance event alone. It does not include natural selection or gene transfer. It brings out random change in allele frequency in the population. Genetic drift is more effective in a small breeding population.

The two waves in the diagram are occupying the same place at the same time
Answer: by adding the amplitude of the two waves
Explanation:
The question pertains to wave superposition in Physics, demonstrating constructive interference and standing waves when two identical waves intersect in opposite directions, leading to an increase in amplitude and fixed points of no motion (nodes) and maximum motion (antinodes).
The question deals with the concept of wave superposition in Physics, specifically the phenomena known as constructive interference and standing waves, which occur when two waves occupy the same place at the same time.
When two identical waves traveling in opposite directions intersect, they can add up at the same points in space, leading to an increase in amplitude. This process is called constructive interference, resulting in wave patterns called standing waves, characterized by their nodes—points where the amplitude is always zero—and antinodes—points of maximum amplitude. The figures mentioned in the question demonstrate these phenomena. For example, Figure 16.33 illustrates pure constructive interference where the amplitude of the resulting wave is twice that of the individual waves due to their perfect alignment in phase, whereas Figures like 12.1.1 and 5.6.5 show standing wave patterns resulting from the superposition.

Match each role within an atom to its correct subatomic particle
Answer:
1 = identity of the atom
2 = acts as a buffer
3 = chemical behavior of atom
Explanation:
The atomic number seen on the periodic table is because of the number of protons. Electrons are lost and gained in chemical reactions. Neutrons are neutral, but do add mass to the nucleus/atom.
Answer:
1. Identity of the atom, matchs with Proton.
2. Chemical behaviour of atom, matchs with Electron.
3. Acts as buffer between protons in nucleus to help stabilize nucleus and add mass to atom, matchs with Neutron
Explanation:
Protons are subatomic particles located in the nucleus, that has a possitive charge and that never change (number of protons remains always the same for a particular element). Because of this property are considered the identity of an atom and defines a constant variable called atomic number.
Electrons are another kind of subatomic particles that are located outside the nucleus and does not contribute with significan amount of mass to the atom. This kind of particles, freely moves around the nucleus and are responsibles for the interaction and formation of bonds between elements (it means of their chemical behaviour).
Neutrons are also located in the nucleus and signifficantly contributes to the total mass of an atom. The sum of neutrons and protons constitute the mass number of an atom.

A single pair of goldfish in a aquarium produced a large number of offspring.
These offspring showed variations in body shape and coloration.
The most likely explanation for these variations is what?
(A.) Offspring were adapting to different environments.
(B.) Parent fish had not been exposed to mutagenic agents.
(C.) Offspring were produced from different combinations of genes.
Answer:
C. Offspring were produced from different combinations of genes.
Explanation:
The offspring would not be adapting to different environments as they all live in the same aquarium. There is no mention of mutagenic agents present in the aquarium and that would have had more of an effect on the parents and not the offspring. The parents may have had different sets of alleles which could produce a variety of phenotypes of their offspring.

happy to help again :)
Answer:
The correct answer is option B (negative gravitropism) and option C (positive phototropism).
Explanation:
Plant seedlings shows downward growth of roots and upward growth of stems due to response of plants to external environmental stimulus via a phenomemon known as tropism.
Plant tropisms are the result of differential growth as cells in area of stem or root grows more quickly than cells in opposite area.this growth determines the directional growth of the entire plants. The directional growth of an organism in response to light is known as Phototropism while directional growth of an organism in response to gravity is known as gravitropism.
Shoot growth in plants shows negative geotropism because they grow away from that force or in opposite direction of the gravity. Also, plants shows positive phototropism as they respond in direction of light.
Thus, option B (negative gravitropism) and option C (positive phototropism) are the right answer.

After photons strike the light absorbing pigment chlorophyll, which of the following occurs
first?
O
Electrons in water get released during photolysis
O
Electrons are transported into the electron transport ch
O
ATP is transformed into glucose.
Electrons in chlorophyll become excited.
:)))
Answer:
Electrons become excited
Explanation:
After photons strike the light-absorbing pigment chlorophyll, electrons within the chlorophyll become increasingly excited. Only after this initial excitation do the electrons begin getting transported into the electron transport chain. Electrons in water molecules get released during photolysis, but only after they first become excited. ATP isn’t transformed into glucose until the light-independent stages of photosynthesis.
After photons strike the light absorbing pigment chlorophyll, the electron in that molecule becomes excited. The correct option is D.
What is chlorophyll?Chlorophyll is the term coined to the green pigment used by plants to produce food throughout the photosynthesis process.
Chloroplasts are plant cell organelles that use photosynthetic energy to revert light energy into fairly stable chemical energy.
They endure life on Earth while doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the metabolism of fats and membrane lipids.
Chlorophyll is excited and emits electrons when it absorbs light. These chlorophylls are discovered in photosynthetic units known as Photosystems I and II.
Each unit has a distinct reaction center containing pigment molecules. These molecules absorb different wavelengths of light and emit electrons.
Thus, the correct option is D.

What happens to the energy stored in the biomass of an organism when it dies?
Answer:
The energy is recycled
Explanation:
This energy is taken by decomposers such as bacteria and fungi and scavengers such as vultures. The biomass is converted to other biomolecules/biomass by these organisms. However, the process is not 100% efficient. Some of the energy is lost as heat.
Is a waste product that uses the most energy to produce
A waste product is a product that is made but isn’t necessarily needed eg. A lightbulb will make light energy but it also makes a waste product heat.
Waste products are nitrogenous wastes excreted from the metabolic processes. Uric acid is a waste product that uses maximum energy to produce. Thus, option B is correct.
What are nitrogenous wastes?Nitrogenous wastes are nitrogen-based products eliminated from the body in various forms like ammonia, urea, and uric acid. Ammonia has one nitrogen and is very toxic.
Urea has two nitrogen and is less toxic. On the other hand, uric acid has four nitrogens and complex molecules although is non-toxic but requires the maximum amount of energy to eliminate four nitrogen.
Therefore, uric acid needs maximum energy.
