Question 1

Sharks and dolphins live in similar habitats and have similar morphologies.This represents an example of

Accepted Answer

Ecological equivalence is when different species evolve similar adaptations in response to similar ecological pressures. In this case, sharks and dolphins both live in similar habitats and have similar morphologies because they both evolved similar adaptations for living in the same environment. This is an example of ecological equivalence, not competitive exclusion, resource partitioning, biological magnification or occupying a specialized niche.

Question 2

The term ecology literally means the study of the ________.

Accepted Answer

The term "ecology" comes from the Greek words "oikos," meaning house, and "logos," meaning study. Therefore, it literally means the study of the "house" or environment.

Question 3

Two closely related plant species live in the same community.One has a shallow fibrous root system whereas the other has a deep tap root system.This represents an example of which of the following?

Accepted Answer

The two species with different root systems are partitioning or dividing up the resource of soil depth, allowing them to coexist in the same community without fully competing with each other. This is resource partitioning.

Question 4

Flying squirrels eat mushrooms that decompose the remains of fir trees - the dominant plants in the forest.Spotted owls eat the flying squirrels.In turn,crows eat the eggs of spotted owls.The crows are which of the following?

Accepted Answer

Crows are tertiary consumers because they eat the eggs of spotted owls, which are secondary consumers (feeding on flying squirrels, which are primary consumers).

Question 5

In the energy dynamics of an ecosystem,the energy is captured by consumers in the which of the following processes?

Accepted Answer

Cellular respiration is the process by which consumers capture energy from food.

Question 6

Which of the following is not a correct association?

Accepted Answer

The answer of Which of the following is not a...

Question 7

Flying squirrels eat mushrooms that decompose the remains of fir trees - the dominant plants in the forest.Spotted owls eat the flying squirrels.In turn,crows eat the eggs of spotted owls.The flying squirrels are which of the following?

Accepted Answer

Flying squirrels are primary consumers because they directly consume mushrooms, which are primary producers (fungi decomposing organic matter). They do not eat other consumers, placing them at the second trophic level, just above producers.

Question 8

Grasses,herbs,herbivores,carnivores,deep organic soils,rapid nitrogen cycling.Found in a typical grassland,collectively these represent a(n)________.

Accepted Answer

The combination of grasses, herbs, herbivores, carnivores, deep organic soils, and rapid nitrogen cycling in a typical grassland represents an ecosystem, which is defined as a community of living organisms interacting with each other and with their physical environment. While these components make up a community of organisms, they also require specific environmental factors and interactions to function as an ecosystem. A population refers to a group of individuals of the same species living in a specific area, while the biosphere refers to the entire global ecosystem, including all living organisms and their physical surroundings.

Question 9

More humans could be fed if they ate more ________.

Accepted Answer

Primary producers refer to plants, which are the base of the food chain. Eating more plants, such as fruits and vegetables, would provide more food for humans than if they were to consume primary, secondary, or tertiary consumers.

Question 10

Tuber gibbosum is a mycorrhizal,truffle-producing fungus that is food for rodents in Pacific Northwest forests.What is T.gibbosum's niche?

Accepted Answer

The answer of Tuber gibbosum is a mycorrhizal,truffle-producing fungus that...

Question 11

Firs trees,spotted owls,rodents,slugs,and various fungal species living in a Pacific Northwest forest constitute a(n)________.

Accepted Answer

A community consists of all the different species living together in a particular area, interacting with each other. The organisms listed are different species living in the same forest, making them a community.

Question 12

Starlings are called the rats of the bird world.They live in a wide variety of environments throughout North America.This represents an example of which of the following?

Accepted Answer

Starlings are able to live in a wide variety of environments, indicating that they occupy a generalized niche. This means they are not limited to a specific set of resources or conditions, but can thrive in many different situations.

Question 13

Turner decided to not mow his lawn for one year and see what happened.After one year,he had a yard full of dandelions.This represents an example of which of the following.

Accepted Answer

Turner's decision to not mow his lawn allowed for the dandelions, an invasive species, to outcompete other plant species and occupy the entire space, demonstrating competitive exclusion.

Question 14

The biomass of tertiary consumers is terrestrial ecosystem is typically less than that of which of the following?

Accepted Answer

The biomass of tertiary consumers is typically less than that of primary producers, primary consumers, secondary consumers, and decomposers due to energy loss at each trophic level in accordance with the principle of energy flow in ecosystems.

Question 15

When a horse eats an apple about 10% of the energy from the apple is available to do cellular work.This is a representation of which of the following?

Accepted Answer

This represents the Second Law of Thermodynamics, which states that energy is always lost in the form of heat when it is transferred or transformed, resulting in less energy being available to do work. In this case, only 10% of the energy from the apple is available to do cellular work, with the rest being lost as heat during digestion and metabolism.

Question 16

Which of the following statements is not correct?

Accepted Answer

Dandelions, coyotes, and humans are not examples of specialists; they are generalists that can adapt to a variety of niches and environments.

Question 17

Which of the following statements is not correct?

Accepted Answer

The statement that renewable resources will never be able to sustain a burgeoning human population is not correct. While some renewable resources have limitations, there are many that can be used sustainably to support human populations. It is important to consider the carrying capacity of our planet and manage resources in a way that promotes sustainability and protects the environment.

Question 18

Flying squirrels eat mushrooms that decompose the remains of fir trees - the dominant plants in the forest.Spotted owls eat the flying squirrels.In turn,crows eat the eggs of spotted owls.The fir trees are which of the following?

Accepted Answer

The fir trees are the dominant plants in the forest, meaning they are the primary producers.

Question 19

Flying squirrels eat mushrooms that decompose the remains of fir trees - the dominant plants in the forest.Spotted owls eat the flying squirrels.In turn,crows eat the eggs of spotted owls.The mushrooms are which of the following?

Accepted Answer

Mushrooms are decomposers, not consumers. They break down dead organic material, such as the remains of fir trees, and recycle nutrients back into the ecosystem. They do not fit into the primary, secondary, or tertiary consumer categories, which are part of the food chain that involves consuming other organisms for energy.

Question 20

Acacia tortillis is the dominant tree of the Serengeti.Collectively the Serengeti A.tortillis represent a(n)________.

Accepted Answer

Acacia tortilis in the Serengeti represents a population because it refers to all the individuals of a single species (Acacia tortilis) living in a specific area.
