Show answer & explanation

Answer

The correct chronological sequence begins with the protagonist receiving an ambiguous omen during an annual festival, followed by the eruption of conflict with traditional elders over a breached taboo, leading to the protagonist's irreversible act of desperation, and concluding with the community restoring order while the protagonist suffers banishment.
Narrative structure follows a logical plot sequence: exposition (receiving the foreshadowing omen), rising action (conflict with traditional elders following a taboo breach), climax (committing an irreversible act of desperation), and resolution (restoration of communal order alongside the protagonist's banishment). Placing these events in this order accurately reflects narrative plot progression.

Step-by-Step Solution

The reception of the ambiguous omen during the annual festival acts as the earliest narrative event.
Expositional events set up foreshadowing prior to the main dramatic complications.
2
Determine the complication that constitutes the rising action.
The breach of ancestral taboo and subsequent conflict with elders escalates tension.
Rising action develops the central conflict stemming from the initial premise.
3
Pinpoint the climax or turning point of the plot.
The protagonist's irreversible act of desperation marks the highest point of dramatic intensity.
The climax represents the decisive turning point beyond which the protagonist cannot return.
4
Identify the resolution and denouement of the narrative.
The restoration of communal order and the protagonist's banishment conclude the narrative arc.
Resolution resolves the aftermath of the climax and brings closure to the plot.

Arrange the following organisms in order of DECREASING available energy in a terrestrial food chain, starting with the organism that contains the highest amount of available energy:

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order from highest to lowest available energy is Grass (Producer) → Grasshopper (Primary Consumer) → Toad (Secondary Consumer) → Hawk (Tertiary Consumer).
The correct sequence begins with the primary producer (Grass), which traps radiant sunlight into chemical energy. Energy is lost as heat at each metabolic transfer step, so primary consumers (Grasshopper) receive less energy than producers, secondary consumers (Toad) receive less than primary consumers, and tertiary consumers (Hawk) receive the least energy.

Step-by-Step Solution

1
Identify the trophic role of each organism
Grass is the primary producer, grasshopper is the herbivore (primary consumer), toad is a carnivore (secondary consumer), and hawk is a apex/tertiary consumer.
Energy flows sequentially from producers through consumers in a food chain.
2
Apply the principles of energy transfer efficiency (10% law)
Energy decreases progressive at each higher trophic level due to metabolic heat loss, respiration, and non-consumed biomass.
Only approximately 10% of energy stored in biomass at one level is transferred to the next level.
3
Sequence the organisms from highest energy to lowest energy
Grass > Grasshopper > Toad > Hawk.
Producers hold the maximum energy, while top predators receive the minimum available energy.

Question 57Question →

In a tropical mangrove estuarine ecosystem, solar energy fixed during primary productivity flows through a sequential food chain. Consider the following four organisms inhabiting this ecosystem:

Arrange these organisms in order from HIGHEST to LOWEST available energy (kJ⋅m−2⋅yr−1kJ \cdot m^{-2} \cdot yr^{-1}) present at their respective trophic levels.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

Red mangrove tree (*Rhizophora mangle*) → Mangrove tree crab (*Aratus pisonii*) → Mangrove snapper (*Lutjanus griseus*) → Osprey (*Pandion haliaetus*)
Energy flow through an ecosystem is unidirectional and non-cyclic. According to the Second Law of Thermodynamics and the 10% energy transfer rule, metabolic respiration, excretion, and heat dissipation result in inevitable energy losses at each step. Consequently, the total available energy per unit area per year strictly decreases from primary producers at the base (Red mangrove tree) to primary consumers (Mangrove tree crab), secondary consumers (Mangrove snapper), and tertiary consumers (Osprey).

Step-by-Step Solution

1
Identify the trophic level and ecological role of each listed organism.
Red mangrove is a primary producer (T1), Mangrove tree crab is a primary consumer (T2), Mangrove snapper is a secondary consumer (T3), and Osprey is a tertiary consumer (T4).
Determining trophic position is essential for establishing the sequence of energy transfer.
2
Apply the principles of ecological energy flow and thermodynamic laws across trophic levels.
Energy flow is strictly unidirectional, with roughly 80% to 90% of available energy lost as heat and metabolic work at each transfer step.
The Second Law of Thermodynamics dictates that energy transformation is inefficient, causing available energy to decrease progressively from lower to higher trophic levels.
3
Sequence the organisms from highest available energy (T1) to lowest available energy (T4).
The correct order from highest to lowest available energy is Red mangrove tree → Mangrove tree crab → Mangrove snapper → Osprey.
Primary producers hold the highest energy budget, while apex predators at the top of the food chain receive the least.

Marine ecosystems display distinct vertical zonation based on environmental gradients such as light penetration, temperature, and pressure. Arrange the following marine depth zones in order from the water surface down to the ocean floor.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from the surface to the ocean bed is Euphotic (Epipelagic) zone, Mesopelagic zone, Bathypelagic zone, and Abyssal zone.
Aquatic marine biomes are vertically stratified according to light availability and depth. Starting from the surface, sunlight fuels the Euphotic zone (0−200 m0 - 200\text{ m}), followed by the dim Mesopelagic zone (200−1000 m200 - 1000\text{ m}), the completely dark Bathypelagic zone (1000−4000 m1000 - 4000\text{ m}), and finally the deep abyssal plain of the Abyssal zone (4000−6000 m4000 - 6000\text{ m}).

Step-by-Step Solution

1
Identify the surface photic layer.
The Euphotic zone is at the top (0−200 m0 - 200\text{ m}).
Sunlight penetrates most strongly at the water surface, driving primary productivity.
2
Locate the intermediate twilight layer.
The Mesopelagic zone lies directly below the photic zone (200−1000 m200 - 1000\text{ m}).
Sunlight rapidly attenuates with depth, creating dim twilight conditions.
3
Determine the upper aphotic layer.
The Bathypelagic zone extends from 1000−4000 m1000 - 4000\text{ m}.
Sunlight is completely absent below 1000 m1000\text{ m} in open ocean waters.
4
Identify the deepest benthic and pelagic abyssal region.
The Abyssal zone sits at the deepest section along the ocean floor (4000−6000 m4000 - 6000\text{ m}).
This zone represents the abyss above ocean trenches.
