If the top level consumers, the apex predators, are poisoned and their population decreases dramatically, then their prey animals have no population control. The prey then has a population boom. In turn, the prey animals decimate their food source, harmng the ecosystem as a whole.
Consumers use in the ecosystem the energy resource at their level of energy as food.The consumers in the plant kingdom at the trophic level are autotrophs and use solar energy while at the next level the consumers are herbivores and the next level the omnivores and finally the decomposers who feed on decayed organism in the ecosystem.
why are there relatively few third-level consumers in an ecosystem?why are there fewer 3rd level consumers in an ecosystem?
yes!
Occupied by producers, not consumers.
Primary level consumers
consumers are organisms that eat other organisms. Depends on what level consumer it is ;).
The secondary consumers (herbivores) occupie s the first trophies level of an ecosystem
I think they are 1st level consumers When i was at school we had to do a poster on an ecosystem and everthing we put into the poster we had to name what level consumer it was and i think coral polyp are 1st level consumers
The group of organisms that occupy the second trophic level of an ecosystem is the herbivores. The herbivores eat the plants in the first trophic level and are then called primary consumers. -Gallo :)
Third level consumers are consumers that feed on second level consumers. A hawk eating a rattlesnake would be an example of a third level consumer. In a forest ecosystem, snakes are third level consumers. Herons and large fish are also third level consumers.
- The organisms have to fit into the energy pyramid- The largest number of organism in any ecosystem needs to be the producers- The smallest number of organism need to be the highest level of consumers in that ecosystem
The second level consumers would have nothing to feed off, and therefore would commence eating themselves. Eventually the ecosystem would die out.
