how can human activities, such as deforestation and habitat destruction, impact the population dynamics of wildlife species?
they can lead to a decrease in available habitats and resources, which can negatively affect wildlife populations.
human activities always benefit wildlife populations.
human activities have no impact on wildlife populations.
they only affect domesticated animals, not wildlife.

Explanation:

• Question 7: Biodiversity is about the variety of life. The first option is about human population (not biodiversity), the third is about a single species (not variety), the fourth is about trees (too narrow). The second option correctly defines biodiversity as the variety of life on Earth including different species.
• Question 8: There are more than three main types of biomes (e.g., aquatic, forest, grassland, desert, tundra etc.). So the statement "There are three main types of biomes" is false.
• Question 9: Deforestation and habitat destruction reduce habitats and resources. Human activities don't always benefit (so second option is wrong), they do have an impact (so third option is wrong), and they affect wildlife (not just domesticated animals, so fourth option is wrong). The first option correctly states that they can lead to a decrease in available habitats and resources, which can negatively affect wildlife populations.

Answer:

1. B. The variety of life on Earth, including different species of plants, animals, and microorganisms.
2. B. False
3. A. They can lead to a decrease in available habitats and resources, which can negatively affect wildlife populations.
