What is the term used to describe the functional role of a species within an ecosystem?

  1. Ecological Niche

  2. Habitat

  3. Trophic Level

  4. Carrying Capacity


Correct Option: A
Explanation:

The ecological niche of a species encompasses its role, interactions, and requirements within an ecosystem, including its habitat, diet, and relationships with other organisms.

Which type of species interaction involves one species benefiting while the other is unaffected?

  1. Mutualism

  2. Commensalism

  3. Parasitism

  4. Competition


Correct Option: B
Explanation:

In commensalism, one species benefits from the presence or activities of another without causing harm or benefit to the latter.

What is the term used to describe the maximum population size that an environment can sustain?

  1. Ecological Niche

  2. Carrying Capacity

  3. Trophic Level

  4. Habitat


Correct Option: B
Explanation:

Carrying capacity refers to the maximum population size of a species that can be supported by the available resources in an environment.

Which type of species interaction involves both species benefiting from each other?

  1. Mutualism

  2. Commensalism

  3. Parasitism

  4. Competition


Correct Option: A
Explanation:

Mutualism is a symbiotic relationship where both species involved benefit from each other's presence or activities.

What is the term used to describe the process by which a non-native species becomes established and spreads in a new environment?

  1. Invasive Species

  2. Endemic Species

  3. Native Species

  4. Range Expansion


Correct Option: A
Explanation:

Invasive species are non-native species that have become established and spread in a new environment, often causing ecological and economic harm.

Which of the following is NOT a potential impact of invasive species on ecosystems?

  1. Competition with native species

  2. Habitat modification

  3. Increased biodiversity

  4. Spread of diseases


Correct Option: C
Explanation:

While invasive species can sometimes increase local biodiversity, they often have negative impacts on ecosystems, including competition with native species, habitat modification, and the spread of diseases.

What is the term used to describe the process by which native species adapt to the presence of invasive species?

  1. Coevolution

  2. Adaptation

  3. Competition

  4. Mutualism


Correct Option: B
Explanation:

Adaptation refers to the process by which native species change their traits or behaviors in response to the presence of invasive species.

Which type of invasive species is known for its ability to rapidly reproduce and spread, often forming dense populations?

  1. Weeds

  2. Insects

  3. Mammals

  4. Birds


Correct Option: A
Explanation:

Weeds are a type of invasive plant species that are known for their ability to reproduce and spread quickly, often forming dense populations that can outcompete native plants.

What is the term used to describe the process by which invasive species are intentionally or accidentally introduced to new environments?

  1. Invasive Species Introduction

  2. Biological Invasion

  3. Species Translocation

  4. Habitat Modification


Correct Option: A
Explanation:

Invasive species introduction refers to the process by which non-native species are brought into new environments, either intentionally (e.g., for agriculture or horticulture) or accidentally (e.g., through shipping or travel).

Which of the following is NOT a potential management strategy for controlling invasive species?

  1. Biological Control

  2. Chemical Control

  3. Physical Control

  4. Habitat Restoration


Correct Option: D
Explanation:

Habitat restoration is not a direct management strategy for controlling invasive species, although it can be used to improve the resilience of ecosystems and reduce the impacts of invasive species.

What is the term used to describe the process by which invasive species spread from one area to another?

  1. Dispersal

  2. Migration

  3. Range Expansion

  4. Invasive Spread


Correct Option: D
Explanation:

Invasive spread refers to the process by which invasive species move from one area to another, often through natural dispersal mechanisms or human activities.

Which type of invasive species is known for its ability to prey on native species, often leading to population declines?

  1. Predators

  2. Herbivores

  3. Parasites

  4. Pathogens


Correct Option: A
Explanation:

Invasive predators are a type of invasive species that prey on native species, often leading to population declines and disruptions in ecosystems.

What is the term used to describe the process by which invasive species modify the physical or chemical characteristics of their environment?

  1. Habitat Modification

  2. Ecological Engineering

  3. Environmental Change

  4. Ecosystem Transformation


Correct Option: A
Explanation:

Habitat modification refers to the process by which invasive species alter the physical or chemical characteristics of their environment, often leading to changes in ecosystem structure and function.

Which of the following is NOT a potential impact of invasive species on human health?

  1. Spread of diseases

  2. Allergic reactions

  3. Increased biodiversity

  4. Economic losses


Correct Option: C
Explanation:

While invasive species can sometimes have positive impacts on human health, such as providing new sources of food or medicine, they can also have negative impacts, including the spread of diseases, allergic reactions, and economic losses.

What is the term used to describe the process by which invasive species are managed or controlled to reduce their impacts on ecosystems and human health?

  1. Invasive Species Management

  2. Biological Control

  3. Chemical Control

  4. Habitat Restoration


Correct Option: A
Explanation:

Invasive species management refers to the process of implementing strategies to control or eradicate invasive species and reduce their impacts on ecosystems and human health.
