In a specific food web, rabbits and turtles both feed off of grass. Come what trophic level do the rabbits belong?


Explanation:

Producers are constantly the lowest level the a trophic hierarchy, and consist the the autotrophs in the system. Organisms the feed off of producers are thought about primary consumers.

You are watching: What is an explanation of why producers are always found at the lowest trophic level?

In this example, the grasses room the producers. Both the rabbits and the turtles will certainly be primary consumers.

An organism that feeds on main consumers is thought about a second consumer.


Explanation:

Autotrophs are organisms that are capable of generating organic energy from not natural sources, together as sunshine in the situation of photoautotrophs. Cyanobacteria room thought to it is in the prokaryotic precursor to chloroplasts through the endosymbiotic theory since they space able to perform photosynthesis. Cyanobacteria are, thus, photoautotrophs. Eco-friendly algae space another kind of photoautotroph.

Heterotrophs use organic materials from the environment to general energy. Pets are heterotrophs, including cows.

Saprotrophs, many of which space fungi, obtain nutrients indigenous decaying necessary material. Mushrooms space saprotrophs.

Example question #3 : Identifying levels


Which of the following specifies a neighborhood in ecology?


Possible Answers:

Group the different types that are found in the same location and interact v each other.


All the living things and also nonliving points that share a typical location and rely top top each other for survival.


Are every the components of planet planet that are able to assistance life.


Organisms that are component of the exact same species, share a geography location and can reproduce v each other.


Correct answer:

Group that different varieties that are found in the same location and also interact v each other.


Explanation:

Ecology is basically the examine of every the living things on the planet and also their relationships v each other. Ecology can be organized into levels: population, community, ecosystem, and biosphere. A population is a team of organisms that belong to the exact same species, share an area, and can reproduce with each other. A community is written of the different types that have the right to be uncovered in a geography location. One ecosystem includes all abiotic and also biotic components in one area. The biosphere describes those components of the planet that space able come support and also sustain life.

Example question #4 : Identifying level


Which the the complying with is an instance of a decomposer?


Possible Answers:

Mushroom


Flower


Caterpillar


Lion


Correct answer:

Mushroom


Explanation:

Within ecosystems, over there is always a carry of energy, usually from one organism to another. There is additionally energy transfer in between abiotic and also biotic factors. The caterpillar and lion are examples of consumers because they are unable to make their own food and must rely on other living organisms for energy. Consumers space subdivided into herbivores, omnivores, and also carnivores. Producers room those living things in the ecosystem that generally develop energy using photosynthesis or light. Biology that failure dead or decaying issue for energy are called decomposers. These space most most likely bacteria, fungi (such as mushrooms), and also some worms.

Example concern #5 : Identifying levels


Which the the complying with is a correct representation the a possible food chain?

 


Possible Answers:

Frog -> Flower -> Caterpillar -> Snake


Caterpillar -> Flower -> Frog -> Snake


Snake -> Caterpillar -> Flower -> Frog


Flower -> Caterpillar -> Frog -> Snake


Correct answer:

Flower -> Caterpillar -> Frog -> Snake


Explanation:

A flower in this example is a producer, which method it will make that is own power through photosynthesis. Together a result, the flower must be the an initial element of ours chain; food chain will always start with a producer. The caterpillar, frog, and snake room consumers, definition they will need other organisms because that energy.

Frog


Fungus


Worm


Green algae


Bear


Correct answer:

Green algae


Explanation:

A producer is an organism that renders its own food from the power of the sun via photosynthesis. Environment-friendly algae is a producer; it has actually chlorophyll pigments and also can make glucose via photosynthesis. A frog is a consumer; a worm is a decomposer; a fungus is a saprophyte; a be affected by each other is a consumer.

A specific insect eats plants. If the plants are producers, what is the insect share as?


Possible Answers:

Predator


Autotroph


Primary consumer


Secondary consumer

Correct answer:

Primary consumer


Explanation:

Organisms the eat producers are recognized as main consumers. Organisms the eat primary consumers are second consumers, and also organisms that eat an additional consumers space tertiary consumers and also so on. Autotrophs space able to settle their own carbon native the air, converting it into food e.g., glucose, and need no eat various other organisms. Predators are animals that eat prey animals, therefore they space a kind of an additional (or higher) consumer.

Example question #9 : Identifying level


The increase in concentration of a pollutant as it moves through an ecosystem is known as __________. 


Possible Answers:

productivity 


biodegradability 


resistance 


biomagnification


Correct answer:

biomagnification


Explanation:

Biomagnification is defined as the concentration of a pollutant boosting as that moves with the tropic level of an ecosystem. Because that example, if a pollutant has a low concentration in a plant, the concentration will be much higher in the pet that eats the plant. This occurs due to the fact that organisms perform not have actually enzymes the can failure these chemicals. This process does not occur through minerals.

Carnivore


Correct answer:
