Answer: It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them.
Where is the lowest trophic level?
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.
What is a trophic level who is the lowest trophic level the highest?
Predators and members of the “top of the food chain” occupy higher trophic levels, while energy producers occupy the lower levels. The correct order from lowest to highest should be the maple tree, caterpillar, cardinal, king snake, and then the fox.
Where is most energy lost in trophic levels?
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
What is trophic level in an ecosystem?
In ecology, the trophic level is the position that an organism occupies in a food chain – what it eats, and what eats it. Wildlife biologists look at a natural “economy of energy” that ultimately rests upon solar energy. … Next are carnivores (secondary consumers) that eat the rabbit, such as a bobcat.
What is the highest trophic level in an ecosystem?
The highest trophic level is the apex predators. Primary consumers are carnivores that survive on secondary consumers (herbivores).
Which marine organism is likely to be at the lowest trophic level?
Primary producers — including bacteria, phytoplankton, and algae — form the lowest trophic level, the base of the aquatic food web. Primary producers synthesize their own energy without needing to eat.
Why each trophic level has less energy than the trophic level below it?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
How is energy lost in an ecosystem?
Energy transfer in ecosystems
About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.
Why there is less energy available at each trophic level going from the first to the third trophic level?
The Organisms must get enough energy to sustain life and reproduce. 90% of the energy an organism gets from the lower level is used up in life processes. … Each tropic level has only 10% of the energy in the level below it that supports that tropic level in the food chain.
What are the three main trophic levels?
Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers.
What are decomposers trophic level?
Decomposers occupy the last trophic level or the top of the ecological pyramid. The most common decomposers are fungi. They are the first instigators of decomposition. They have the enzymes and other compounds to break down the biomolecules of the deceased organism.
