The Pattern Of Population Density In Species C's Exponential Growth?

Since organisms living in communities form interdependent relationships, a change in the abundance of one species will not only affect the physical and more direct interactions, but could indirectly affect the number of other species within the community as a consequence (Wootton 1993). These indirect affects rise because the interactions between pairs of species are not independent of other species, such as increasing the density of vegetation may increase the survival rate of the prey, reducing the intensity of the interaction between the predator and prey (Wootton 1993, 1994). An

The local animals population is decreasing because the Python snakes are eating them. According to the text, “With no natural predators, these eating machines appear to be wiping out huge numbers of opossums, raccoons, and bobcats, as well as many bird species." This supports that the local animal population is decreasing because the snakes are eating the animals since the python snake population is growing then the other animals population is decreasing. The more snakes

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.

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

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.

b) Species A is the predator and species B is the prey. When species B’s population increases, it allows for the increase in population for the predator species.

In this situation, not only did one species’ population decline, but a study showed that almost one third of the current species of birds are endangered. There reason for declining has more to do with the changing environment around them rather than the changing humans around them. Granted, the environment is changing substantially due to humans, so they are technically similar in the sense that in both problems, humans contribute to the downfall of species. There was also some good news in the article, stating that certain other species did rise in population, similar to how the wolves’ population has gotten bigger up until

For instance, gray wolves, according to the authors of “Using Small Populations of Wolves for Ecosystem Restoration and Stewardship”, “...influence the abundance of ungulates, which in turn affects the structure and composition of plant communities”(Licht et al. 2). Wolves prey on herbivores such as deer and elk, keeping their population under control and thus allowing more plant species that the prey feed on to grow and reproduce. If wolves were to go extinct the prey populations would soar. There would be no predators to hunt the animals, so they would spend less time worrying about predators and more time feeding. This would drastically reduce the population of plant species that the prey animals feed on until there is not enough food to sustain the ever growing prey species. The prey species population would begin to die of starvation and the few animals left would develop a variety of diseases due to malnutrition and genes that were passed through generations of animals. The genes would have not passed through the animals if the wolves had not gone extinct. This is due to the fact that wolves would have eaten the weak prey animals, therefore reducing the chance of weak and sickly offspring and improving the health of future generations of prey animals. Additionally, with the plant

One example is what humans did to the siberian tiger population. If humans hadn’t been killing it for fur, wine, and all of that other junk that they don’t need, there would be more than 4,000 of them today. The siberian tigers are also a main predator in the biome,

Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses.  Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species.  Invasive species

Over the past years, there has been an exceptionally large national increase which has caused several population issues. These issues include: homelessness, deforestation and more fields being used to make space for shops and houses disrupting the biodiversity growth. Problems like this are caused when there is an abnormal increase in the birth rate where more babies are born; this is also known as a ‘baby boom’. This can occur when nations have more children as a whole and events like this normally takes place after an achievement – an example being when we won the World War Two. The country was relieved that the fighting was over so their instantly celebrated which is why more children were born. In the last 50 years alone, the population has doubled showing just how fast the population is actually growing and even though it may seem fortunate that there are less recorded deaths, this makes the Economical

Issue: The environmental issue that I have chosen is the impact that invasive species have on the environment. The impact that invasive species have on the environment is vast, yet little is done about it. This issue is extremely important and will impact the world for generations to come. In this paper, I hope to learn about the effect they have on environment and what we can do about it.

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!

Have you ever wondered how the earth's processes have changes populations of organisms? Well, they can either drastically decrease or increase depending on what's happening in that area or environment.There are many people that would not waste time paying attention to things like these, but they should because you never know if it can affect you too. There are many ways the earth can bring up populations or destroy them such as specific resources, weather or climate, finding preserved remains, or even when DNA strands change.
