Bill Nye Video Quiz-biodiversity

The correct answer is Rocks, sand, and seawater. These are all nonliving parts of an environment because they do not possess the characteristics of living organisms. Rocks and sand are inorganic substances, while seawater is a mixture of water and various minerals. They do not have cells, do not grow or reproduce, and do not have the ability to respond to stimuli. Therefore, they are considered nonliving components of the environment.

Biodiversity refers to the variety of different types of plants and animals that exist within a particular ecosystem. It encompasses the range of species, genetic diversity, and ecosystems found in a given area. Biodiversity is important for maintaining the balance of ecosystems, as each species plays a unique role in the functioning of the ecosystem. It also provides various ecosystem services, such as pollination, nutrient cycling, and pest control, which are essential for human well-being.

Extinction is the term used to describe the complete disappearance of a species. When a species becomes extinct, there are no individuals of that species left alive. This can occur due to various factors such as habitat loss, overhunting, pollution, or natural disasters. Extinction is a serious concern as it disrupts the balance of ecosystems and can have cascading effects on other species and the environment. Efforts are made to prevent extinction through conservation and protection measures.

The correct answer is Oceans. Oceans cover about 71% of the Earth's surface and are home to a wide variety of plants, animals, and microorganisms. They play a crucial role in regulating the Earth's climate, providing oxygen, and supporting a diverse range of ecosystems. Oceans are also a major source of food and resources for human populations.

Using a lot of fertilizer and insecticide on our lawns is not a way to promote biodiversity because these chemicals can harm and kill beneficial insects, birds, and other wildlife. Biodiversity is important for maintaining a healthy ecosystem, and using excessive chemicals can disrupt the balance of the ecosystem and harm the diversity of species.
