Ecology and Genetic Engineering Concepts

The video tutorial by Mr. Stano covers ecological niches, comparing fundamental and realized niches, and the differences between generalist and specialist species. It explains resource partitioning as a strategy to avoid competition and discusses evolutionary divergence leading to speciation. The video also highlights mass extinctions, human impact on the environment, and the role of genetic engineering, touching on ethical debates surrounding these topics.

What is the difference between a fundamental niche and a realized niche?

• A fundamental niche is the actual role an organism plays, while a realized niche is its potential role.

• A fundamental niche is the potential role an organism could play, while a realized niche is the actual role it plays.

• A fundamental niche is the role an organism plays in competition, while a realized niche is its role in adaptation.

• A fundamental niche is the role an organism plays in adaptation, while a realized niche is its role in competition.

Which type of species is more likely to survive environmental changes?

• Generalist species

• Specialist species

• Endangered species

• Extinct species

What is resource partitioning?

• The division of resources among species to avoid competition

• The creation of new resources to avoid competition

• The sharing of resources among species to increase competition

• The elimination of resources to reduce competition

What is adaptive radiation?

• The process by which species compete for the same resources

• The process by which species migrate to new environments

• The process by which species evolve to exploit different resources

• The process by which species become extinct

How does geographic isolation lead to speciation?

• By causing species to become extinct

• By isolating populations and leading to genetic differences

• By preventing species from adapting to new environments

• By increasing competition among species

What is a major concern regarding current extinction trends?

• The potential for a new mass extinction due to human activities

• The extinction of only large mammals

• The extinction of species that are not affected by climate change

• The extinction of species that are not important to ecosystems

What is the role of genetic engineering in evolution?

• To artificially alter genetic characteristics of organisms

• To prevent any changes in genetic makeup

• To eliminate all genetic diversity

• To create new species through natural selection

What is recombinant DNA technology used for?

• To prevent species from evolving

• To eliminate genetic mutations

• To transfer genes from one species to another

• To create new species naturally

What is a potential benefit of genetic engineering?

• It can eliminate the need for natural resources

• It can prevent all environmental changes

• It can improve human conditions by enhancing food production

• It can lead to the extinction of unwanted species

What ethical concerns are associated with genetic engineering?

• It may increase the natural selection process

• It may lead to the creation of new species

• It may cause unpredictable results and ethical dilemmas

• It may prevent species from becoming extinct
