Writeacher, am I allowed to guess options too, or would that be cheating? I'm not very sure....
Thx @Noddles ;) You're 100%
I am fr, Ms. Sue has died from brain cancer on November 8, 2019... R.I.P., Ms.Sue, I miss her.
_-_
She is a retired teacher, she and writeacher, and bobpursly, they are all retired. please don't be mean to a dead person. that's straight sins.
I'm not a bot
I spent hours of my time here copying and pasting.
I hope you do it too, to spread the knowledge
1. The correct answer to this question is D. Cutting down trees in rain forests to build more houses has a negative impact on biodiversity. To arrive at this answer, we need to understand what biodiversity means. Biodiversity refers to the variety of life forms, including plants, animals, and microorganisms, and the ecological roles they play in a particular ecosystem. Cutting down trees in rain forests destroys the natural habitat of many species and disrupts the delicate balance of the ecosystem, thereby negatively impacting biodiversity.
2. The correct answer to this question is B. The koala population would decrease significantly if their habitats are destroyed to build houses. To determine this, we need to understand the habitat requirements and diet of koalas. Koalas primarily depend on eucalyptus trees for their food and shelter. If their habitats are destroyed, they would lose their source of food and shelter, leading to a decrease in their population.
3. The correct answer to this question is B. Rain forests are the most diverse ecosystem because they have a favorable climate. To understand this, we need to consider the factors that contribute to the high diversity of species in rain forests. Rain forests have a combination of high temperature, humidity, and rainfall, which create a favorable environment for a wide range of plants and animals to thrive. The combination of these factors leads to the high biodiversity observed in rain forests.
4. The correct answer to this question is C. Biodiversity is ecologically valuable because it establishes the foundation for food chains and food webs. To arrive at this answer, we need to understand the ecological importance of biodiversity in maintaining the functioning of ecosystems. Biodiversity ensures the availability of different species, which in turn contribute to the stability and resilience of ecosystems. Each species in an ecosystem plays a specific role, such as being a predator, prey, or decomposer, and these roles form intricate food chains and food webs that sustain the ecosystem.
5. The correct answer to this question is A. Preservation of biodiversity prevents the extinction of species. To understand this, we need to consider the importance of preserving biodiversity in maintaining the balance of ecosystems and ensuring the long-term survival of species. Biodiversity provides a variety of species, each with their unique traits and adaptations. If species become extinct, it can disrupt the delicate balance of ecosystems and lead to negative cascading effects. By preserving biodiversity, we can protect species from extinction and maintain the functionality and resilience of ecosystems.
