Without the primary consumers there would be no source of energy for carnivores or secondary consumers so no secondary consumers would exist in that ecosystem. … The producers would be the only organisms in the ecosystem, besides decomposers. The producers would likely over reproduce.
Is it possible to have an ecosystem without producers and or carnivores explain your answer?
Explain. There could not be a food chain without herbivores and carnivores because there would no one left toe at each other event to eat the producers.
Could there be an ecosystem without herbivores and carnivores?
So, in answer to our question, although there would be drastic changes in biodiversity of an ecosystem, the food chain would survive without herbivores and carnivores. … Without producers, there would be no food chain.
Can an ecosystem survive without carnivores?
An ecosystem is a community of interacting organisms, together with their abiotic environment, through which energy flows and within which nutrients cycle. If you are referring to vertebrate carnivores, then, yes, it is certainly possible for an ecosystem to exist and thrive without carnivores.
Can an ecosystem exist without predators?
Without any predators to limit population growth, herbivorous prey species reproduce without check, and all of them are hungry. More herbivores eat more plants, and without anything to control them, they can quickly degrade their habitat.
Can an ecosystem survive with only producers?
The path of food and energy from producer to consumer to decomposer is a food chain. … However, although an ecosystem can exist without consumers, no ecosystem can survive without producers and decomposers. The simplest food chain is producer —>• decomposer.
Can there be an ecosystem only has carnivores?
In an ecosystem, can there be more carnivores than herbivores? … No, because there only could be more herbivores because they only eat plants and don’t rely on other animals as their source. There needs to be more primary producers (plants) then Primary consumers (herbivores) then secondary consumers (carnivores).
What would happen if there were no more producers in an ecosystem?
Producers are the autotrophs or plants which act as a source of food and energy for the consumers by making their own food and consumers eat them as their food for energy. … So, if there were no producers, the food chain would not initiate and all the living species on earth would die.
What would happen if there were no carnivores?
Answer: The carnivores keep the populations of other carnivores and herbivores in check. If there were no carnivores, the herbivore populations would explode and they will rapidly consume large amounts of plants and fungi, growing until there is not enough food to sustain them.
What would happen if there were no carnivores on earth?
Herbivore populations would rise if there were no carnivores and they would swiftly consume vast amounts of plants and fungus, growing until there was no more food to sustain them. The herbivores would eventually starve, leaving only the plants that they disliked or were poisonous to them.
What happens if there is no food chain?
Answer: When any organism is removed from a food chain, the rest of the food chain is disrupted. … When those animals die out due to lack of food, the secondary consumers who feed on the primary consumers will have no food source, and so on.
Why are carnivores important to the food chain?
Carnivores play an important role in many ecosystems, and by preying on herbivores, they ensure that plants and vegetation aren’t grazed into extinction. A diverse and balanced food chain is key to a healthy ecosystem, but in general carnivores are declining worldwide.
What would happen to animals if there were no plants?
When green plants make food, they give off oxygen. This is a gas that all animals must breathe in order to stay alive. Without plants, animals would have no oxygen to breathe and would die. … All animals eat either plants or plant-eating animals.
What are keystone species and why are they important?
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. Keystone species have low functional redundancy.
What do you think an ecosystem looks like without its top predator being present?
When a top predator is no longer present, populations of their herbivorous prey begin to boom. Without a top predator to regulate their numbers, these animals put a great deal of pressure on the existing vegetation that they require for food and can destroy large amounts of plant life, such as grasses and trees.
Why carnivores would go extinct without the sun?
Why would carnivores go extinct without the Sun? Carnivores do not produce their own food or eat green plants, but the organisms that they do eat get their energy from green plants, which get their energy from the Sun. … They will need to find another food source or they will not survive.
