- The _______________ signifies that species richness is greater where two communities meet than at the center of either community. (a) edge effect (b) fundamental niche (c) character displacement (d) realized niche (e) limiting resourceA niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.The Law of 10 determines all the following characteristics except one. Which one characteristic does the Law of 10 NOT determine? Group of answer choices The abundance of individuals at various trophic levels The amount of energy stored in the combined biomass of various trophic levels The combined mass of individuals at various trophic levels The length of food chains The number of species at various trophic levels
- 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.A 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. True FalseA(n) ______ niche is all the conditions that species could survive in, whereas a(n) _____ niche is a species’ actual occupied niche for which it is best adapted.
- A niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem. Northern Pacific TreeFrog California Red Legged FrogWhich of the following situations show a biotic factor operating within an ecosystem? the rate of water flow in a body of water the kind of climate in a given region the concentration of hydrogen gas in the air carnivores that eat other animalsWhich of the following attributes of a community would tend to lead to higher species richness? High specialization of species A broad resource spectrum High population size in each species Both a and b Both b and c
- Which one of the following statements is FALSE? Beta diversity is low when two ecosystems share the similar species and respective abundance. An intelligent meander records date, time, location and a list of species. Beta diversity or differentiation diversity compares alpha diversity among several communities. Species richness is the total species abundance in an ecosystem. Inventory diversity can be defined by alpha diversity, which is the number of species in a local forest stand.Which of the following statements about biotic potential is TRUE? Biotic potential of an organism is determined by how they interact with the environment. Increase in food supply increases the biotic potential of an organism. If an organism has higher rate of reproduction, it has higher biotic potential. Small organisms have low biotic potential because of their size.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.…
