If a predator organism was removed from an ecosystem, it would allow the prey population to increase which could lead to not having enough food for these organisms to eat. For example, if wolves were eliminated from the taiga biome than there would be a dramatic increase in the population of moose. This would result in the moose not having enough jack pine and could lead to starvation. The wolves would then have to eat more rabbits, elk, and voles which would decrease their population and starve the organisms that rely on these animals. Yes, an organism can be a secondary and a tertiary consumer in the same ecosystem. For example, a fox can eat a moose which makes it a secondary consumer but then it can eat a rabbit which makes it a tertiary …show more content…
There should always be more producers to feed the consumers or else the organisms would starve or become extinct. If there is not enough food for the primary heterotroph than it would become very difficult for the secondary heterotroph and the tertiary heterotrophs to eat. This would disrupt a food chain which would lead to a dramatic change in a food web. If all the primary heterotrophs became extinct, there would currently be no more herbivores. The population of producers would increase since primary heterotrophs are most likely going to be herbivores. This would then affect carnivores population by decreasing since they don't have any herbivore to feed on or hunt. The population of omnivores would also decrease because they have a lower variety of organisms to feed on. This would then lead to the population of decomposers to increase since many organisms are dying out. If a non native beetle began to kill most of the autotrophs than the number of organisms would decrease. The herbivores would die out and that would lead to the omnivores and the carnivores having to rely on meat, which means many will starve and die out especially if an organism only eats one
Explain why the biomass of the primary consumers is less than the biomass of the producers in most communities. .......................................................................................................................................................
them into the autotrophs and secure their position at the bottom of the food chain,
This in turn would lead to more consumption at the top of the food chain, eliminating the predators to creatures at the lower end
The effects of their endangerment, and possible extinction, could potentially lead to our populations decreasing at alarming rates. The Earth would lose
The topography of the island is also of note. The west end of the island features a closed-canopy forest with more hardwood trees. The east end of the island is better characterized as a “boreal forest,” a term used to describe regions that are mostly covered by coniferous forests. It is good to note that the balsam fir is found on both ends of the island, but that samples used in the study from the west end of the island were, on average, older, but shorter, than those samples found on the east side of the island.
Say a frog eats a caterpillar, then a snake eats the frog, then finally a owl eats the snake. This is just a simple food chain but something called biodiversity, which means that’s there is a variety of things a that one animal can eat. An owl cant only eat a snake it could eat the frog or something smaller like a worm. This keeps form one species dying out completely, which would cause multiple species to die out. When someone releases a pet into the wild they are causing a disturbance into the wild habitat. When a python is released into a place full of crocodiles these two will start competing for food which would cause all of the lower species to start lowing in numbers faster until they become extinct which would then make the snakes and the crocodile die off too. If this keeps on happening the eventually every animal would die off!
-Reintroduction of a top predator lowered the number of over grazing herbivores, leaving a more stable amount of food for many species of herbivores.
Chapter 1: In chapter one, Moose introduces himself and his sister and the people who live around him. He also describes where he lives and describes notorious gangsters like, Al Capone, Machine Gun Kelly and many other criminals who live near him. Moose Flanagan also was getting suspicious of who put the note that said “Done.” He was thinking of Al Capone because he sent a letter to Al Capone asking if he could help his sister Natalie get into the Esther P. Marinoff School, since she has already been rejected twice.
If an organism is extinct, it will affect the whole food web. Even if the organism was just endangered or populations declined, it will still affect the food web. For example: The grey wolf is a predator that had been missing from the Yellowstone ecosystem for decades. Although they weren’t extinct, there was no control on elk’s population. The increasing population started eating and consumed most of the willow.
In the ecosystem organisms rely on each other for food and protection. The Food chain is like a pyramid you have the producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers. It’s an almost perfect balance and if any level were to just stop existing then the food chain would be destroyed. An example of organisms relying on others is an issue of isle royale were the wolves and moose population are in jeopardy. This relationship is important because without the other animal the population would die.
The exact scenario changes in each example, but the central idea remains that through a chain of interactions, a non-abundant species has an outsized impact on ecosystem functions.
Moose isn't much of a sleeper. He tends to stay up at night, thinking and dreaming about what if's and should of been's. He is rarely even able to go to sleep with such thoughts, but when he does, he's usually woken up by a quiet noise, or his brother. His brother, who actually decides to go by Max, is an eighteen year old boy that has a very annoying personality. Him and Moose are completely different people, yet share many qualities. For instance, both have brown hair and aren't very tall, but they do have sparkling caramel colored eyes and perfect teeth.
Isle Royale is an interesting island, where people can find wolves and moose interacting with little human influence. However, the wolves are inbred and are few in numbers. So, what is going to happen? The wolves might die out. That is the plan of action that humans should take. Human influence shall not happen because this issue was not caused by human influence, the moose already have a population control, and it could hold interesting results.
Obviously the decline in pollinator species is a much more noticeable difference because with the loss of these, humans are going to be affected. First world nations consume resources at an absolutely extreme rate. For example, humans on average eat three to four pounds of food per day. Not all the foods we eat are also the diet for animals. Even still, if you take that three or four pounds per person and calculate it with a population the size of the US, or even worse, China, the amount will add
Loss of Biodiversity will affect the life cycle of several species which depend on each other for survival. This dependence determines the survival of species and the change of our environment. Exploiting the biodiverse species to extinction will result in desertification, rise in carbon dioxide in the atmosphere, increased pollution, increased droughts, increase in loss of items that we derive from nature for our own survival such as honey, fruits, vegetables, medicines etc. The greed to exploit will result in our ultimate extinction If a sustainable solution isn’t provided to prevent loss of biodiversity. If we continue the path we are on without taking steps to balance the equation the planet will
