Chapter 44, Problem 2TY
Summary Introduction
Introduction:
The number of dissimilar species characterized in a landscape, ecological community or region is called as species richness. If you have many species, more species will be prosperous so there will be a stable ecosystem. The increase in biodiversity is contributed by the species richness, which is a significant aspect of biodiversity conservation.
'Equilibrium Model of Island Biogeography’ was presented by the two American ecologists, Robert McArthur and E.O. Wilson in 1960. This model is rated by the balance between 2 factors: the migration rate and the extinction rate.

A group of ecologists want to test if an industrial effluent affects the diversity of aquatic invertebrates in a river. To do this, they compare the community of aquatic invertebrates between two sites: one upstream of the effluent and one downstream of the effluent. Which variable should they calculate to compare the diversity of the two communities of invertebrates?
The carrying capacity of the river
The net reproductive rate
The Shannon Index
The gross primary productivity of the river
The instantaneous rate of growth
Which of the following statements about the concept of ecological niche is correct?
A species' realized niche, may or may not be the same as its fundamental niche
The fundamental niche of a species includes biotic and abiotic factors while the realized niche only includes biotic factors

- What is the relationship between the biodiversity of an ecosystem and the productivity of an ecosystem? equal inversely proportional directly proportional There is no relationship.arrow_forwardThe competitive exclusion principle is best defined as Multiple Choice the competition among individuals of the same species in the same location. the principle that two species that occupy the same niche cannot coexist indefinitely. an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual. the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.arrow_forwardCommunity - Competition. Competition between species on the same trophic tier leads to four potential outcomes, 3 are deterministic (zero sum games where one species goes extinct and the other maximizes their growth to balance at the carrying capacity) and one where both competitors survive, but neither does well. This dynamic suggests that extirpation (local extinction) of populations is a far more likely outcome than co-existence. How, in your opinion, does this affect management policies aimed at increasing biodiversity and proliferation of inter and intra population and interspecies variation. Reason your point of view. Endangered species are defined by low growth rates (r ) and low K (reflecting high demand for resources). What are the implications of both these factors on the outcome of competition scenarios, especially the most common scenario of alternate stable states?arrow_forward
- In some marine habitats in New England, the population density of lobsters has been depleted due to heavy fishing. When this happens, it often follows that the diversity of species in the biological communities is reduced. Based on this observation, how would you characterize lobsters? a keystone organism a decomposer a crustacean a superior predator a producer The composition of a community refers to the nutrients available in the soil. type of succession that occurs locally. sunlight available to drive the energy needed for metabolism. extent vegetation covers the ground--a desert has low composition. types of species adapted to living there. Small fish sometimes swim very close to large predatory fishes such as sharks. There is no risk since the shark does not feed on these smaller fish. The small fish are able to eat the remains of prey such as seals that the shark rips apart when eating.…arrow_forwardWhich of the following is a conclusion drawn by the authors from the results of this study? Temperate marine invertebrate species are outcompeting endemic species which will soon become extinct in the surveyed areas. Tropical marine invertebrate species did replace temperate species from 1982 to 2021 in the surveyed areas. Tropical marine invertebrate species did not replace temperate species from 1982 to 2021 in the surveyed areas. The temperate marine invertebrate species density and richness will recover with sufficient monitoring and resources.

Wellsarrow_forwardAccording to the competitive exclusion principle, two species cannot exist together if they occupy the same niche. Either they diverge their niches so they can coexist or one species will die out.All of the following are consistent with the principle of competitive exclusion EXCEPT Select one: a. Birds and bats both consume flying insects, but birds are active in the day and bats are active at night. b. Two species that share the same niche will exclude other competing species. c. Different bird species forage for insects in different parts of the same tree. d. When two species of Paramecium are grown in the same medium, one strain will eventually eliminate its competitor.arrow_forward
- Two species of bird live in the same tree. Seeds only grow at the tops of the tree and insects only live at the bottom of the tree. Bird species A lives in the tops of the trees and eats both insects and seeds. Bird species B lives in the bottom of the tree and only eats insects. Which of the following describes why these two species live together in the same community? Group of answer choices Species A and Species B have the same fundamental niche. Species A and Species B have the same realized niche. Species A and Species B have a different fundamental niche. Species A and Species B have a different realized niche.arrow_forwardTrue or False: Among the three types of ecological pyramids, the most useful is the pyramid of biomass because it shows how much kilocalories are available at each trophic level.arrow_forwardA realized niche describes the conditions of the environment in which a species is actually found, while a fundamental niche describes the potential environmental conditions tolerated by a species.

They have introduced a number of the species that constitutes 25 percent of the population that the island is capable of supporting. If the growth rate of the species is 11 percent, find what percentage of the maximum the particular species population will be on the island in three years.arrow_forwardThe smallest population of a species that is likely to be able to survive in the long term is called the_________ . When suitable habitat for a given species is split up into areas that are too small to support a large enough population, this is called_______ .
