Question

Organisms of a higher trophic level that feed on several types of organisms belonging to a lower trophic level constitute the

• A. Food web
• B. Ecological pyramid
• C. Ecosystem
• D. Food chain

Answer 1

The correct option is A

Food web

The correct option is A.

Explanation of the correct option:

1. All of the food chains in an ecosystem make it into a food web.
2. Each organism in an ecosystem resides at a certain trophic level, position, or web of relationships with other organisms.
3. It forms many feeding links among different creatures in a community by interconnecting at various trophic levels.
4. A food web is similar to a food chain, with the exception that it is much larger.
5. Food can be obtained in a variety of ways.
6. For instance, squirrels and grasshoppers both eat vegetation.
7. The lizard consumes the grasshopper before being consumed by the fox.
8. A fox or a golden eagle may eat a squirrel.

Explanation of the incorrect option:

Option B:

1. An ecological pyramid is a diagram that shows the biomass or bio productivity at each trophic level in a specific environment.
2. A sample space of a few numbers or a few species will end up generating a huge degree of errors, therefore all calculations for the development of these kinds of ecological pyramids must account for all the animals at a certain trophic level.

Option C:

1. An ecosystem is a region where various plant, animal, and animal-related species interact with the topography and weather to form a living bubble.
2. Ecosystems support the "Biosphere" and keep the planet's natural balance.
3. Take the ecological interaction between sheep and lions, where the lion consumes the sheep to ensure its life.
4. Additionally, each of these relationships has an impact on the nearby animals and plants.

Option D:

1. A food chain is a set of interconnected links in a food web that begins with producers and ends with apex predators, detritivores, or decomposer species.
2. The food chain is a succession of living things that transmit nutrients and energy from one organism to the next.
3. When one organism ingests another, this happens.

Final answer: Organisms of a higher trophic level that feed on several types of organisms belonging to a lower trophic level constitute the food web.
