d. competitive exclusion

Ok oh my god i’ve been searching similar spieces that are found together for the past 4 hours!! At first I did lions and tigers but lions live in africa and tigers live in asia therefore they are not often found together. I need two species that usially compete for food and if possible in the same “family”. Like pigeons and sparrows are from the “bird family” Ok plzz help with these questions:
Choose two similar species that are often found together (like pigeons and sparrows).
Find three locations where both species live.
Hypothesize how the features of each location affect the population of each species.
Is there evidence of competitive exclusion or niche differences? Explain.
Thanks

. A population of foxes experiences an exponential growth. After this period of growth, the birth rate within the population slows down. What has happened within the population? The population has gone through ecological succession. The environment of the population has most likely reached its carrying capacity.
The population has experienced competitive exclusion. The habitat of the population has experienced population dispersion.
14. Which type of population dispersion is shown below?
even random
clumped sparse
15. Which of the following factors is an example of interspecies competition? a population of zebras and a population of wildebeests grazing in the same region a population of wild horses that share a watering hole
a pack of wolves that hunt deer and moose a population of penguins that feed on fish
16. Lily and her classmates decide to plant a garden at a local park. Lily decides that it would be a good idea to investigate the local plant life of the region before the class plants the garden. Why does Lily investigate local plant life before her class decides what vegetation to plant? Lily wants to make sure that the class does not plant exotic or nonnative plants in the garden. Introduced species can be harmful to local habitats. Lily wants to make sure that the class plants only nonnative vegetation, so that the plants will not have to compete for resources within the environment.
Lily wants to make sure that the plants will be able to survive in the local environment. Lily wants to make sure that the native plants will not interfere with the growth of the class’s garden.
17. The fungus on the ear of corn in the image below is called corn smut. If an ear of corn is infected with the fungus, it has to be destroyed, or it could spread and cause harm to the entire population. The fungus found on the ear of corn is an example of _____.
natural selection genetic drift
a limiting factor gene flow
18. Which of the following populations is the most likely to have reached its carrying capacity? a population of birds that inhabit a large forest where resources are abundant and competition is low a population of birds that inhabit a small, wooded area where resources are scarce and competition is high
a population of birds that inhabit a small, wooded area where resources are abundant and competition is high a population of birds that inhabit a large forest where resources are limited and competition is low
19. Which of the following is the most likely outcome for a community that has multiple species with high population density? The species within the community will experience genetic drift because of the limited habitat space. The species within the community will undergo mutation to better adapt to the limited habitat space.
The species within the community will share niches to better adapt to the limited habitat space. The species within the community will experience high levels of interspecies competition over habitat space that could lead to competitive exclusion.
20. Why do populations that have clumped population dispersion compete and rely on each other more than organisms that live in populations with even and random dispersion? The organisms in even or random populations generally do not require the same resources. The organisms that live in clumped populations generally do not require the same resources.
The organisms that live in clumped populations share a more compact habitat space. Organisms that live in even or random populations experience greater interspecific competition.
21. Why does the presence of mimicry reflect how interactions shape community structure? Mimicry limits the ability of predators to find food. Mimicry exists only in communities that experience high competition.
Mimicry increases prey survival, increasing the food supply for predators. Mimicry only develops as a result of the interactions that exist between predators and prey in a community.
22. Mycorrhizae are a type of fungi that grow on the roots of plants. In order to survive, the fungus must attach itself to a host. In turn, the fungus produces high amounts of nitrogen that is released into the soil and helps the host plant grow and complete life functions. Which type of relationship best describes this interaction? mutualism parasitism
commensalism predation
23. The polar bear population is found naturally only in the extremely cold climate of the Arctic Circle. As a result, the polar bear has adapted in several ways to make it better suited to living in these climates. Which of the following is an adaptation that is a result of the polar bear’s cold climate?
its massive size, which helps it overpower prey the long hair found between the pads of its feet, which helps it walk on icy surfaces
the stiff hairs found on its hind legs and broad paws, which help it swim

1. _____ is the number of organisms within the same species that inhabit a specific area. Population density Exponential growth
Population dispersion A limiting factor
2. What is a community? a group of different species that inhabit the same environment a group of organisms that are of the same species and share a habitat
the species, abiotic factors, and biotic factors that inhabit the same environment the abiotic factors of a habitat
3. When one organism hunts another organism, what type of relationship exists? symbiotic predation
mutualism commensalism
4. _____ are organisms moved from their native environment to a new, nonnative habitat. Niches Parasites
Introduced species Communities
5. Even, random, and clumped all describe types of _____? exponential growth population density
population dispersion limiting factors
6. Which of the following is NOT an example of a limiting factor? habitat space availability of food
outbreak of disease migration
7. What causes interspecies competition within a community? when two or more species compete for resources when a single species dominates the food supply
when two species have different dietary requirements when a single species requires a variety of food sources
8. If there has been a competitive exclusion within a community, what has occurred? A species that had previously competed for food has been eliminated from the community by a more efficient species. Limiting factors have decreased competition within the community.
The carrying capacity of the habitat has been reached. Two species that previously competed for food have begun to share the resources equally.
9. In which of the following relationships do both of the organisms involved benefit from one another? predation mutualism
commensalism parasitism
10. Which of the following factors influence the global distribution of ecosystems?
I. atmospheric circulation
II. oceanic circulation
III. land formations
IV. local environmental conditions
I and II I and III
I, II, and IV I, II, III, and IV
11. Before the 20th century, the growth of the human population was relatively _____. rapid slow
unstable exponential
12. No two species in a single community occupy the same _____. population ecosystem
niche habitat

The dissapearance of a population in a given niche as a result of direct competiton with another species for a resource is called….
A. Competitive exclusion
B. Predation
C. Parasitism
D. Commensalism
-thanks for the help!!

I understand competitive exclusion but wouldn’t the same logic extend to the animals of the same species if we’re going to take competitive exclusion to this extreme?
