Conservation and Biodiversity Concepts

The video explores the concept of biodiversity, its importance, and the threats it faces, such as habitat loss, fragmentation, degradation, invasive species, and acid rain. It discusses the impact of climate change on ecosystems and the importance of conservation and restoration ecology in maintaining biodiversity and ecological balance.

What is biodiversity and why is it crucial for ecosystems?

• It is the genetic variation within a species and is crucial for evolution.

• It is the number of species in a zoo and is important for tourism.

• It is the number of plants in a forest and is important for oxygen production.

• It refers to the variety of life in an area and is essential for ecosystem balance.

Which of the following is a primary cause of habitat loss?

• Natural disasters

• Decreased sunlight

• Increased rainfall

• Land conversion for development

How does habitat fragmentation affect ecosystems?

• It increases biodiversity by creating more habitats.

• It isolates species, reducing genetic diversity.

• It has no significant impact on ecosystems.

• It improves ecosystem services by diversifying resources.

What is an invasive species?

• A native species that thrives in its environment

• A non-native species that causes harm to its new environment

• A species that is beneficial to agriculture

• A species that is endangered

What is a consequence of acid rain on forests?

• It enhances tree growth by providing nutrients.

• It dissolves essential nutrients in the soil, harming trees.

• It has no effect on forest ecosystems.

• It increases the biodiversity of forest species.

How does climate change impact biodiversity?

• It disrupts ecosystems by altering species distributions and interactions.

• It stabilizes ecosystems by maintaining current species distributions.

• It has no effect on biodiversity.

• It increases biodiversity by creating new habitats.

What is the focus of climate change ecology?

• Studying the effects of natural climate variations on ecosystems

• Understanding the impact of human-induced climate change on ecosystems

• Analyzing the benefits of climate change on agriculture

• Exploring the role of climate change in geological formations

What is in-situ conservation?

• Conservation of species in zoos and botanical gardens

• Conservation of species in their natural habitats

• Conservation of species in laboratories

• Conservation of species in artificial environments

Why is restoration ecology important?

• It focuses on the economic benefits of ecosystems.

• It is only important for urban development.

• It supports the renewal of degraded ecosystems.

• It helps in creating new ecosystems from scratch.

What is a key goal of conservation efforts?

• To increase the number of zoos worldwide

• To preserve biodiversity and restore natural habitats

• To eliminate all non-native species

• To focus solely on endangered species
