Why is biodiversity important for ecosystems?

• Biodiversity has no impact on ecosystems

• Biodiversity only benefits certain species in ecosystems

• Biodiversity actually harms ecosystems

• Biodiversity is important for ecosystems because it ensures the stability and resilience of the ecosystem, enhances ecosystem productivity, provides essential ecosystem services, and supports the overall health of the planet.

• tundra, taiga, temperate deciduous forest, tropical rainforest, grassland, desert, and aquatic

• tundra, taiga, temperate deciduous forest, tropical rainforest, grassland, desert, and aquatic

• tundra, taiga, temperate deciduous forest, tropical rainforest, grassland, desert

• tundra, taiga, temperate deciduous forest, tropical rainforest, grassland, aquatic

What factors determine the type of biome in a particular area?

• Geological activity, ocean currents, and wildlife diversity.

• Climate, precipitation, temperature, soil type, and topography.

• Population density, land use, and pollution levels.

• Altitude, wind patterns, and vegetation.

What is a keystone species?

• A keystone species is a species that has a negative impact on its environment relative to its abundance.

• A keystone species is a species that has a small impact on its environment relative to its abundance.

• A keystone species is a species that has a disproportionately large impact on its environment relative to its abundance.

• A keystone species is a species that has no impact on its environment.

How does a keystone species impact its ecosystem?

• A keystone species helps maintain the balance and diversity of its ecosystem.

• A keystone species disrupts the balance and diversity of its ecosystem.

• A keystone species has no impact on its ecosystem.

• A keystone species only impacts a small portion of its ecosystem.

How can we protect and conserve biodiversity?

• Promoting the use of pesticides and chemicals in agriculture

• Encouraging overfishing and unsustainable fishing practices

• Implementing measures such as deforestation and habitat destruction

• Implement measures such as creating protected areas, promoting sustainable land and water management practices, reducing pollution and waste, implementing conservation programs and policies, and raising awareness about the importance of biodiversity.

Explain the concept of ecosystem services and how it relates to biodiversity.

• Ecosystem services are the benefits humans obtain from ecosystems, and they are closely related to biodiversity.

• Ecosystem services are the benefits humans obtain from the economy, and they are closely related to biodiversity.

• Ecosystem services are the benefits animals obtain from ecosystems, and they are closely related to biodiversity.

• Ecosystem services are the negative impacts humans have on ecosystems, and they are closely related to biodiversity.
