Why would we expect the primary consumers herbivores to be more plentiful than top carnivores?
Because we lose energy each time we move up a trophic level, we have more producers than consumers, more herbivores than carnivores, more primary consumers than secondary consumers. See this Socratic answer for more detail.
Why population of top consumer are always smaller than the population of herbivores?
Propose an explanation for why populations of top carnivores, such as hawks, are always smaller than the population of herbivores, such as caterpillars. Animals at the top have less energy because they only get 10% of the energy of the organism it gets it from.
What is the best explanation for why food chains usually do not exceed three to four levels?
The different feeding positions in a food chain or web are called trophic levels. Generally, there are no more than four trophic levels because energy and biomass decrease from lower to higher levels.
Why are there more producers than herbivores?
There is always more biomass in lower trophic levels than in higher ones. Because biomass decreases with each trophic level, there are always more autotrophs than herbivores in a healthy food web.
What is the three types of consumers?
Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow.
What are consumers State two examples?
Consumers have to feed on producers or other consumers to survive. Deer are herbivores, which means that they only eat plants (Producers). Bears are another example of consumers. Black bears are omnivores and scavengers, like skunks and raccoons, which means that they will eat just about anything.
Which organism is a tertiary consumer?
The larger fishes like tuna, barracuda, jellyfish, dolphins, seals, sea lions, turtles, sharks, and whales are tertiary consumers. They feed on the primary producers like phytoplankton and zooplankton, as well as secondary consumers like fish, jellyfish, as well as crustaceans.
