Chpt 7.2: What Role Do Humans Play in Loss of Species?

What is habitat destruction and how does it contribute to the loss of species?

• Habitat destruction reduces the available space and resources for species to survive and thrive.

• Habitat destruction increases the available space and resources for species

• Habitat destruction has no impact on species loss

• Habitat destruction only affects a few species, not the overall biodiversity

Explain the concept of habitat fragmentation and its impact on species loss.

• Habitat fragmentation has no impact on species loss

• Habitat fragmentation increases species diversity

• Habitat fragmentation only affects non-native species

• Habitat fragmentation can lead to loss of biodiversity and species decline.

How does overhunting lead to the decline of species populations?

• By promoting the balance of the ecosystem

• By reducing the number of individuals in a population, disrupting the balance of the ecosystem, and causing the loss of genetic diversity.

• By causing an increase in genetic diversity

• By increasing the number of individuals in a population

What are the consequences of overhunting on the ecosystem?

• Overhunting can lead to the decline or extinction of certain species, disrupt the food chain, and alter the balance of the ecosystem.

• Overhunting has no impact on the ecosystem as it is a natural process.

• Overhunting leads to an increase in the population of certain species, creating a more balanced ecosystem.

• Overhunting can improve the biodiversity of the ecosystem by introducing new species.

What are invasive species and how do they affect native species and ecosystems?

• Invasive species are non-native organisms that cause harm to the environment, economy, or human health. They can outcompete native species for resources, disrupt ecosystems, and reduce biodiversity.

• Invasive species have no impact on native species and ecosystems.

• Invasive species are native organisms that benefit the environment and increase biodiversity.

• Invasive species are only harmful to the economy and human health, not the environment.

Describe the process of introduction of invasive species and its impact on biodiversity.

• Invasive species only impact a small portion of the ecosystem and do not disrupt the balance

• Invasive species have a positive impact on biodiversity by increasing species diversity

• Invasive species are introduced through human activities such as trade, travel, and agriculture, and they can negatively impact biodiversity by outcompeting native species and disrupting ecosystems.

• Invasive species are naturally occurring and do not require human introduction

What are the different types of pollution that can harm species and their habitats?

• Food pollution, clothing pollution, technology pollution, space pollution, land pollution

• Air pollution, water pollution, soil pollution, noise pollution, light pollution

Explain the concept of biomagnification and its role in species loss due to pollution.

• Biomagnification is the process of decreasing concentration of a substance as it moves up the food chain, leading to lower levels of toxins in top predators and potential species loss.

• Biomagnification is the process by which the concentration of a substance increases as it moves up the food chain, leading to higher levels of toxins in top predators and potential species loss.

• Biomagnification has no role in species loss due to pollution.

• Biomagnification only affects the lower levels of the food chain and has no impact on top predators or species loss.

How does deforestation contribute to the loss of species and biodiversity?

• Deforestation only affects non-essential species

• Deforestation has no impact on species and biodiversity

• Deforestation destroys habitats and disrupts ecosystems, leading to the displacement and extinction of many species.

• Deforestation helps to increase the population of species

Discuss the impact of deforestation on the habitat and survival of species.

• Deforestation has no impact on species habitat and survival

• Deforestation increases the available habitat for species

• Deforestation only affects a few species, not the majority

• Deforestation reduces the available habitat for species, leading to displacement and extinction.
