Which of the following is at the highest trophic level?
Notes: Omnivores constitute the highest trophic level in an ecosystem. Omnivores are tertiary consumers and feed on both plants and animals. Decomposers feed on all the trophic levels.
What does highest trophic level mean?
The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5.
What occupies have the lowest trophic levels?
The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
Which of the following trophic levels contain animals that eat herbivores quizlet?
Examples of tertiary consumers include hawks and owls that eat rodents that have eaten grasshoppers. Most primary consumers are herbivores because they consume plants, whereas secondary and tertiary consumers are carnivores because they eat animals.
Which species occupy is the highest trophic level and why?
In general, the highest trophic level is occupied by adult animals with no predators of their own.
What is the highest trophic level of the ecological pyramid?
Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.
Which species occupies the highest trophic level and why quizlet?
In general, the highest trophic level is occupied by adult animals with no predators of their own.
Which species occupies the highest trophic level and why?
The highest trophic level is the apex predators. Primary consumers are carnivores that survive on secondary consumers (herbivores).
What is organism trophic level?
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.
Which trophic level contains the most energy and largest populations?
Since the source of energy is the sun, the trophic level representing producers (plants) contains the most energy.
What is true about organism at the highest trophic level?
The higher the organism is on the trophic pyramid, the lower the amount of available energy.
What trophic level do autotrophs occupy?
first trophic level Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level). Producers make up the first trophic level. Producers, also known as autotrophs, make their own food and do not depend on any other organism for nutrition.
What are the 5 trophic levels in order?
In a system with five trophic levels, organisms are classified on their pattern of subsistence. The five levels include: primary producers (plants), primary consumers (herbivores), secondary consumers, tertiary consumers, and detritivores (decomposers).
Which trophic level has the highest energy in an ecosystem?
producers According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis.
Which trophic level has the highest source of energy?
Since the source of energy is the sun, the trophic level representing producers (plants) contains the most energy.
At which trophic levels number of organisms is the lowest and the highest?
Solution : In a food chain, maximum number of organisms are at first trophic level (at producers level) and minimum number of organisms are at fourth trophic level (higher carnivores). Step by step video solution for (object Object) by Biology experts to help you in doubts & scoring excellent marks in Class 10 exams.
Which organism would be at the top of the trophic pyramid?
apex predators Consumers at the highest trophic level are called apex predators.
What are the 7 trophic levels?

What organism has the highest energy level?
autotrophs According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis.
Which trophic level has the highest energy which has the lowest energy Why?
The higher the organism is on the trophic pyramid, the lower the amount of available energy. For example, plants and other autotrophs (primary producers) convert only a fraction of the enormous amount of solar energy they have access to into food energy.
Which trophic level has highest number of organisms and why?
Solution : In a food chain, maximum number of organisms are at first trophic level (at producers level) and minimum number of organisms are at fourth trophic level (higher carnivores).
Who is at the top of the food chain?
apex predators Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow. At the top of the system are the apex predators: animals who have no predators other than humans. Help your class explore food chains and webs with these resources.
Which is the highest trophic level class 10?
> The trophic level of an organism is the number of steps it is from the start of the chain. > A food web starts at trophic level 1 with primary producers such as plants, then to herbivores(primary consumers) at level 2, carnivores(secondary consumers) at level 3 or higher, and apex predators at level 4 or 5.
At which trophic level of ecosystem highest level of energy is obtained?
According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis.
Which among the organisms in the given food chain receives the highest amount of energy from the producer?
autotrophs According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis.
What type of organism is found at the top of the food pyramid?
shark Organisms on the first trophic level, such as plants and algae, are consumed by organisms on the second trophic level, such as conchs and blue tangs. At the top of the food web is an apex predator, a shark.
Which trophic level has maximum organisms and why?
Solution : In a food chain, maximum number of organisms are at first trophic level (at producers level) and minimum number of organisms are at fourth trophic level (higher carnivores).
Which organism receives the highest amount of energy?
According to the pyramid of energy the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis.
Who is on top of the food chain?
species at the top of the food chain, with no predators of its own. Also called an alpha predator or apex predator. one of three positions on the food chain: autotrophs (first), herbivores (second), and carnivores and omnivores (third).
What type of organism is at the first trophic level?
Producers make up the first trophic level. Producers, also known as autotrophs, make their own food and do not depend on any other organism for nutrition. Most autotrophs use a process called photosynthesis to create food (a nutrient called glucose) from sunlight, carbon dioxide, and water.
