Biodiversity and Ecosystems

What is biodiversity?

• The process of evolution

• Variety of life forms

• The study of celestial bodies

• Different types of rocks

Name three different types of ecosystems.

• Desert ecosystems, mountain ecosystems, and city ecosystems

• Aquatic ecosystems, forest ecosystems, and grassland ecosystems

• Tundra ecosystems, beach ecosystems, and cave ecosystems

• Jungle ecosystems, desert ecosystems, and ocean ecosystems

What is the importance of biodiversity in ecosystems?

• Ecosystems function better with fewer species

• Biodiversity is important in ecosystems because it contributes to the stability of the ecosystem and provides a variety of resources for human use. It also plays a crucial role in maintaining the balance of the food chain and helps in the adaptation of species to changing environmental conditions.

• Human activities have no effect on biodiversity

• Biodiversity has no impact on ecosystems

What are the main threats to biodiversity?

• Habitat destruction, climate change, pollution, overexploitation, and invasive species are the main threats to biodiversity.

• Hunting, fishing, and agriculture are the main threats to biodiversity.

• Urbanization, deforestation, and overpopulation are the main threats to biodiversity.

• Disease, natural disasters, and genetic mutations are the main threats to biodiversity.

Define the term 'ecosystem'.

• A community of living organisms in conjunction with the nonliving components of their environment interacting as a system.

• The process of converting waste materials into reusable materials.

• The study of rocks and minerals.

• A group of people living in a specific area.

What is the role of keystone species in an ecosystem?

• Keystone species only benefit themselves and do not contribute to the health of the ecosystem

• Keystone species are harmful to the ecosystem and disrupt the balance

• Keystone species have no significant role in maintaining the balance and diversity of an ecosystem

• Keystone species help to maintain the balance and diversity of an ecosystem by regulating the population of other species and maintaining the health of the ecosystem.

What is ecological resilience?

• The ability of an ecosystem to withstand and recover from disturbances or changes while maintaining its essential structure, function, and feedbacks.

• The ability of an ecosystem to resist any form of disturbance or change.

• The ability of an ecosystem to recover from disturbances or changes without any impact on its structure or function.

• The ability of an ecosystem to adapt to changes in its environment.

How does climate change affect biodiversity?

• Climate change only affects a few species of animals.

• Climate change has no impact on biodiversity.

• Climate change affects biodiversity by altering ecosystems and habitats, causing species to migrate or go extinct, disrupting food chains, and changing the timing of natural events like flowering and migration.

• Climate change actually increases biodiversity.

What are some ways to promote biodiversity conservation?

• Building more factories and industries

• Clearing forests for urban development

• Using pesticides and herbicides in agriculture

• Creating protected areas, implementing sustainable land and water management practices, promoting sustainable agriculture and forestry, reducing pollution and waste, raising awareness and education about biodiversity, and supporting research and monitoring efforts.

Explain the concept of ecological succession.

• Ecological succession is a man-made process that can be controlled and reversed.

• Ecological succession only occurs in aquatic ecosystems.

• Ecological succession is the process of gradual change in an ecosystem over time, involving the replacement of one community by another.

• Ecological succession is the process of sudden change in an ecosystem, involving the replacement of one community by another.
