Biodiversity

Why is low biodiversity a concern for an ecosystem?

• It increases the resilience of the ecosystem.

• It can lead to instability in the ecosystem, causing food web collapse.

• It enhances the genetic diversity of species.

• It promotes the growth of invasive species.

What is the significance of species interactions in a community?

• They are irrelevant to community dynamics.

• They only affect individual species, not the community as a whole.

• Species interactions, such as predation, competition, and symbiosis, are crucial for maintaining the balance and health of a community.

• They only occur during specific seasons.

What is biodiversity and why is it important in an ecosystem?

• Biodiversity refers to the number of species in a habitat, and it is important because it increases competition among species.

• Biodiversity refers to the variety of life in a particular habitat or ecosystem, and it is important because high biodiversity allows ecosystems to withstand disturbances and maintain functionality.

• Biodiversity is the total number of organisms in an ecosystem, and it is important because it ensures that all species have enough resources to survive.

• Biodiversity is the genetic variation within a species, and it is important because it helps species adapt to changing environments.

Why is genetic diversity important within species?

• It increases the likelihood of inbreeding.

• It enhances a population's ability to adapt to environmental changes and resist diseases, ensuring long-term survival.

• It reduces competition for resources among individuals.

• It leads to a higher rate of mutation in the population.

What role do producers play in an ecosystem?

• Producers convert sunlight into energy through photosynthesis, forming the base of the food web and providing energy for herbivores.

• Producers are organisms that consume other organisms for energy and nutrients.

• Producers are responsible for decomposing organic matter in the ecosystem.

• Producers compete with herbivores for sunlight and nutrients.

How can conservation efforts help maintain biodiversity?

• By promoting urban development and industrial growth.

• By preserving ecosystems and the species that inhabit them.

• By increasing pollution and habitat destruction.

• By encouraging overfishing and hunting of endangered species.

How does biodiversity contribute to ecosystem resilience?

• By providing a wider range of species that can adapt to changes and disturbances, ensuring the ecosystem can recover.

• By reducing the number of species in an ecosystem, which simplifies interactions.

• By increasing competition among species, leading to resource depletion.

• By creating more habitats that are less stable and more prone to collapse.

What is the relationship between biodiversity and ecosystem services?

• Biodiversity has no impact on ecosystem services.

• Biodiversity is directly linked to ecosystem services, as diverse ecosystems provide essential services such as pollination, water purification, and climate regulation.

• Ecosystem services are only dependent on climate change, not biodiversity.

• Biodiversity decreases the efficiency of ecosystem services.

What factors can threaten biodiversity in an ecosystem?

• Habitat destruction

• Overpopulation of species

• Increased agricultural practices

• Natural disasters

What is an example of a keystone species and its impact on biodiversity?

• Sea otter, which helps maintain ecosystem structure and biodiversity

• Dolphin, which is known for its intelligence

• Shark, which is a top predator but not a keystone species

• Goldfish, which is commonly kept in aquariums
