The highest trophic level would have the lowest number of organisms.
What trophic level would have the smallest population?
Because there are losses in energy between levels, the population between levels also diminishes. With less energy, there are less creatures that can be supported by it, so the level with the least amount of creatures would be the tertiary consumers, while the level with the most organisms would the producers.
Which trophic level is most likely to contain the largest population of organisms within an ecosystem?
The first trophic level contains the greatest number of organisms and is comprised mainly of plants. The organisms in this layer are called primary producers because they get their energy from an abiotic source. Most primary producers get their energy directly from the sun.
What is the lowest trophic level in an ecosystem?
The lowest trophic level is primary producers, such as algae and phytoplankton, which generate their own energy from the sun via photosynthesis. Primary consumers, such as herbivorous zooplankton, must eat primary producers as their source of energy.
Which trophic level would have the least amount of available energy?
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.
Which organisms have the smallest population?
With a population of fewer than 300 individuals, the vaquita porpoise (Phocoena sinusis) is the world’s smallest and most endangered cetacean, a group of marine mammals that includes whales, dolphins and porpoises.
Which organism has less biomass?
The level with the least biomass are the highest predators in the food chain, such as foxes and eagles. In a temperate grassland, grasses and other plants are the primary producers at the bottom of the pyramid.
Which trophic level contains autotrophic organisms?
Because autotrophs do not consume other organisms, they are the first trophic level. Autotrophs are eaten by herbivores, organisms that consume plants. Herbivores are the second trophic level.
Which trophic level has the greatest biomass?
Explanation: In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers. These include things like grass, trees, and flowers.
Which trophic level contains photosynthetic organisms?
The trophic level that contains photosynthetic organisms is the first level. Photosynthetic organisms are the producers, or autotrophs in an…
What is the highest trophic level?
The highest trophic level is the apex predators. Primary consumers are carnivores that survive on secondary consumers (herbivores).
What is secondary trophic level?
The second trophic level is made up of primary consumers or herbivores, third of secondary consumers or carnivores, fourth of tertiary consumers such as animals that feed on other carnivores.
Which occupies the highest trophic level?
Omnivores (plant and meat eaters) occupy the highest trophic level. Carnivores that consume other carnivores are also placed at this level. These are called tertiary consumers. Every ecosystem must include another class of consumers called detritivores or decomposers.
Which trophic level has the smallest biomass?
The trophic level that has the least biomass is usually the tertiary consumers.
Why populations of top consumer are always smaller than the populations of herbivores?
Propose an explanation for why populations of top carnivores, such as hawks, are always smaller than the populations of herbivores, such as caterpillars. Because only ~10% of the energy gets transferred up the pyramid, it takes a lot of the previous level to sustain the next higher level.
Which level has the least energy in an energy pyramid?
The top level of an energy pyramid has the fewest organisms because it has the least amount of energy.
