In a food chain, trophic levels are defined as the number of steps that are followed by one another in the process of energy flow and are also dependent on each other for food.
What is trophic level class 10th? Answer: Trophic Levels : The various steps in a food chain at which the transfer of food (or energy) takes place are called trophic levels. Example : A food chain operating in a grassland is given below : Grass → Insects → Frog → Birds. In this food chain.
Similarly, What trophic level is Brainly 10? ➝ The various steps in a food chain at which the transfer of food or energy take place is called trophic level. In other words trophic level means feeding of the organism.
What are decomposers class 10th?
Hint: Decomposers are the organisms that decompose the dead organisms and break down the complex compounds of dead organisms into simple nutrients. They play a very important role as they decompose the complex compounds (dead organisms) into simple components.
What is an ecosystem Class 10?
Ecosystem refers to a system that includes all living organisms ( Biotic factors) such as plants, animals, microorganisms etc in a habitat as well as its physical environment ( Abiotic factors) such as weather, soil, earth, sun, climate, rocks minerals etc, functioning together as a unit.
How many trophic levels are there?
All food chains and webs have at least two or three trophic levels. Generally, there are a maximum of four trophic levels. Many consumers feed at more than one trophic level. Humans, for example, are primary consumers when they eat plants such as vegetables.
What is trophic level answer in one word? A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain.
What is a trophic level for 1 mark? The number of steps an organism is from the start of the chain is a measure of its trophic level. Food chains start at trophic level 1 with primary producers such as plants, move to herbivores at level 2, predators at level 3 and typically finish with carnivores or apex predators at level 4 or 5.
What are trophic level give an example of food chain and state the different trophic level in it Brainly in?
Textbook solution
The trophic level is defined as the functional level that is occupied by an organism in the food chain. For instance, the primary trophic level is occupied by the producers or the autotrophs; the second level includes the herbivores, whereas the successive levels are occupied by the carnivores.
Why there is no waste in forest? It is considered waste when plants and animals die in the forest. When they die, microbes in the soil assist in the conversion of waste into humus or nutrients for the soil, that are then utilised by plants. As a result, there are no waste materials in the forest.
What are decomposers short answer?
Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi.
Why are green plants called producers? The organisms that are capable of preparing their own food from simple inorganic substances like carbon dioxide and water by using sunlight energy in the presence of chlorophyll are called producers. The green plants synthesize their own food through the process of photosynthesis and thus are called the producers.
What is biome Class 9?
Define a biome. Ans. A very large ecosystem on land having distinct types of vegetation and animal life is known as a biome.
What is biodiversity class 11?
In simple terms, biodiversity is the number and variety of organisms found within a specified geographic region. It refers to the varieties of plants, animals and micro-organisms, the genes they contain and the ecosystems they form.
What is 10% law of energy? Ten percent law
According to this law, during the transfer of organic food energy from one trophic level to the next higher level, only about ten percent of the transferred energy is stored as flesh.
What trophic level are decomposers?
They are the “last trophic level” in some hierarchies because they feed on everything (National Geographic). However, according to the strict trophic level definition they would be primary consumers.
How do you know what trophic level you are?
Trophic Index and Efficiency
Trophic level is defined as the position of an organism in the food chain and ranges from a value of 1 for primary producers to 5 for marine mammals and humans. The method to determine the trophic level of a consumer is to add one level to the mean trophic level of its prey.
What trophic level are humans? The World’s Food Chain
Next come the omnivores that eat a mixture of plants and herbivores. That’s where humans rank, with a trophic level of 2.2.
What is a trophic level quizlet?
Trophic Level. A set of species occupying one level of the ecological food chain. Primary Producers. Lowest organisms on food chain which can create their own energy from energy like sunlight and molecules like carbon dioxide.
What is the 4th trophic level called? Trophic Levels
| Trophic Level | Where It Gets Food |
|---|---|
| 1st Trophic Level: Producer | Makes its own food |
| 2nd Trophic Level: Primary Consumer | Consumes producers |
| 3rd Trophic Level: Secondary Consumer | Consumes primary consumers |
| 4th Trophic Level: Tertiary Consumer | Consumes secondary consumers |

Why is it dark inside a forest?
It is dark inside a forest because the canopy leaves intercept the sunlight available to the forest. As a result, less than 50% of total sunlight falling on the top of the forests manage to pass through the canopy and go down to the plants in the forest.
What happens if an animal dies in a forest? When the animals die, they are decomposed by the microorganisms present in the soil. The microbes break the dead organisms into simpler organic forms and mix with soil to increase soil fertility. The plants are dependent upon the fertility of soil for their growth.
Why forests are called green lungs?
Plants release oxygen through the process of photosynthesis which helps the animals for respiration. They also maintain the balance of oxygen and carbon dioxide in the atmosphere. That is why the forests are called green lungs.
