Studies of two species of blackbirds showed that red-winged blackbirds establish nests mostly on the edges of marshes, but also extend throughout the marsh if yellow-headed blackbirds are absent. Yellow-headed blackbirds can nest only in the middle of marshes, regardless of the presence of red-winged blackbirds, because they require wetter habitat. Based on this, which of the following statements are true? Select all that apply. The realized niches of the two species differ. OThe fundamental niche of red-winged blackbirds is larger than its realized niche. The fundamental niche of red-winged blackbirds is larger than the fundamental niche of yellow-headed blackbirds. The fundamental and the realized niches of red-winged blackbirds are the same. The fundamental and the realized niches of yellow-headed blackbirds are the same.

What is the principle that teaches us that two species cannot coexist in the exact same niche in the same habitat.This is because species with same niches have comparable requirements, which implies they would fight for the same resources.
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 A species' fundamental niche is always smaller than its realized niche A niche is the same as a habitat
When populations of ocean perch and herring are reduced, which other species in this ecosystem are directly affected? Identify at least two species that directly lose their food source.
A 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.
According 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.
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 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
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 False
For various reasons, some species prefer to live on the edge of a habitat patch while others fare better if they stay near the middle of a patch. In areas with a mosaic of grassland and woodland, warbler fledglings are more likely to survive when their parents nest in the core rather than the ecotone, because the ecotone is also habitat for brown-headed cowbirds. What is the name for the behavior of cowbirds that poses a risk to warblers? Give typing answer with explanation and conclusion
If you had to monitor an ecosystem for evidence of pollution, what are one or two indicator species you would want to pay particularly close attention to? You may discuss specific species of organisms, or can discuss organisms that occupy a specific trophic level in an ecosystem’s food web. Explain why you would select these species or this trophic level.
How is fire ants current range likely to change as a result of climate change? Things that you don't want to miss in your answer to get a high score: Define any terms such as range, niche. Do they prefer or are they limited by weather? What happens to their spread as weather changes The evidence for their limitation by cold weather is in the reading, and you should know that some species, particularly invasives, may spread as the climate warms.
Two species of aquatic snails live in a nearby creek. Species A is a very strong competitor of Species B, who is a weak competitor. What do you expect will happen to the realized niche of Species B if both species share the same fundamental niche?a. increaseb. decreasec. stay the same
